Weather in Portugal: Region-by-Region Guide (2026)

Introduction

If there is one question expats ask more than any other before moving to Portugal, it is "what is the weather really like?" The short answer is that Portugal has more climatic variety than almost any other country in Western Europe, and the wrong answer costs real money: pick the wrong region and you will either melt in summer, freeze in a damp winter, or spend six months wishing the rain would stop. The right answer depends entirely on what kind of climate you want to live in — and which trade-offs you can tolerate.

Portugal is roughly 600 km from top to bottom on the mainland, plus two Atlantic archipelagos. That is enough latitude, longitude, and altitude variation to produce at least seven distinct climate zones: the rainy north, the moderate Atlantic centre, the dry interior, the hot and dry south, the cool Atlantic coast, the subtropical Madeira, and the oceanic Azores. Within each zone, microclimates matter: the north side of a mountain can get twice the rainfall of the south side, and a city 30 km inland from the coast can be 5°C warmer in summer and 5°C colder in winter than the coast itself.

This guide walks through each major region with month-by-month temperatures, rainfall, and sunshine hours. The data is drawn from IPMA (Instituto Português do Mar e da Atmosfera), the official Portuguese weather service, with 30-year averages updated through 2024. Use it to compare the regions and pick the one that matches the climate you actually want, not the one you saw in a travel brochure.

The Big Picture: Portugal's Three Climate Zones

Portugal sits at the western edge of the Iberian Peninsula, with its entire mainland and island territories exposed to Atlantic weather systems. Three broad climate zones matter for expats:

1. The North Atlantic Zone. Minho, Douro, and Trás-os-Montes. Cool summers (22–27°C highs), mild winters (5–14°C), and significant rainfall (1,200–2,000 mm per year). Porto, Braga, and Guimarães are in this zone. The climate is green, lush, and similar to coastal Galicia, Ireland, or the UK southwest — but milder in winter and warmer in summer.

2. The Central Atlantic Zone. From Coimbra down through Lisbon and the Silver Coast to the western Algarve. Mild summers (25–28°C coastal highs, hotter inland), mild winters (8–15°C), moderate rainfall (700–1,000 mm per year). The climate is the Mediterranean-style one most people picture when they think of Portugal — sunny, dry summers and wet, mild winters.

3. The South and Interior Zone. The eastern Algarve, the Alentejo, and the Beira Interior. Hot, dry summers (often 35–42°C), cool winters (3–14°C with occasional frost), low rainfall (300–600 mm per year). The climate is closer to southern Spain or inland Andalusia than to coastal Portugal.

The islands add two more zones: subtropical Madeira (mild year-round, 17–26°C, low rainfall on the south coast) and oceanic Azores (cool, wet, four-season, similar to the UK or Ireland but milder).

Lisbon and the Tagus Valley

Lisbon has the climate that most expats are imagining when they decide to move to Portugal: mild winters, warm dry summers, around 2,800 sunshine hours per year, and a moderate Atlantic influence that prevents the worst extremes.

Lisbon's climate is the closest thing to "perfect" in mainland Portugal, but it has two important caveats. First, summer nights are warm but not unbearable — typical July low of 18°C means you will want a fan, occasionally AC. Second, winter mornings can be damp and cold-feeling even at 8–10°C, because of the humidity. The city is also exposed to Atlantic storms in November and December, which can bring heavy rain and wind for 1–3 days at a time. For the detailed neighborhood guide, see our Lisbon neighborhoods article.

Inland, the Tagus Valley (Santarém, Lezíria) is significantly hotter in summer — 35–40°C days are common in July and August, with 10°C warmer nights than Lisbon. Winters are colder too, with occasional frost. The Setúbal Peninsula south of Lisbon has a similar climate to the city, slightly warmer and drier.

Porto and the North

Porto is greener, rainier, and cooler than Lisbon. It is the climate that surprises expats the most — particularly those arriving from the Mediterranean, the UK, or the US Northeast, who expect something drier or warmer.

Porto gets about 1,450 mm of rain per year — roughly double Lisbon's total. The rain is concentrated between October and April, often as long periods of light drizzle (the famous Porto "molha" — light drizzle that soaks you through in 20 minutes). The Atlantic influence keeps summer temperatures in a comfortable 24–27°C range, with sea breezes that make the city livable. Winters are mild for the latitude (rarely below freezing), but the dampness makes 8°C feel colder than 4°C in dry continental climates. Snow is rare, occurring once every 3–5 years and melting within hours. For the detailed Porto guide, see our Porto neighborhoods article.

North of Porto, the Minho (where Braga sits) is even greener and slightly cooler in summer, with more annual rainfall. The Douro Valley is more extreme: cold winters with frost in the higher vineyards, very hot summers (often 38–42°C in July and August), and the lowest rainfall in northern Portugal thanks to the rain shadow of the Marão mountains. Trás-os-Montes (Bragança, Mirandela, the northeast) is continental — long cold winters with snow, hot dry summers, and the most extreme temperature swings in the country.

The Algarve

The Algarve is the climate most travel guides describe when they sell Portugal. It is the sunniest, driest, and most consistently warm region in mainland Portugal — but it has its own surprises, particularly the difference between the western coast (cooler, windier, Atlantic-facing) and the eastern Algarve (warmer, drier, more Mediterranean).

The eastern Algarve (Tavira, Vila Real de Santo António, Castro Marim) is the driest and sunniest part of Portugal, with annual rainfall below 500 mm and over 3,000 sunshine hours. The central Algarve (Faro, Albufeira, Loulé) is similar. The western Algarve (Lagos, Sagres, Aljezur) is significantly cooler and windier, with more Atlantic influence and lower summer temperatures (often 25°C vs 30°C in the east). The west coast is also more exposed to Atlantic storms in winter. For the full region deep dive, see our Algarve living guide.

The Silver Coast and the Central Coast

The Silver Coast (Costa de Prata) — from Figueira da Foz up through Nazaré, São Martinho do Porto, Caldas da Rainha, and Foz do Arelho — has a climate that is the closest thing to the "real" Atlantic Portugal that most expats picture: warm dry summers, mild rainy winters, and ocean influence year-round. It is cheaper than the Algarve and has fewer tourists, but the weather is more variable.

The Silver Coast is roughly 2–3°C cooler than Lisbon in summer and similar in winter, with more wind and more rain. It is the climate that delivers the most "real" Portuguese weather for the price. The area is popular with British, German, and French expats who want the lifestyle of the Algarve without the prices or the summer crowds. For the deep dive, see our Silver Coast living guide.

Coimbra and Aveiro are slightly cooler and wetter than the Silver Coast, with more fog in winter and late autumn. The interior Beira (Viseu, Guarda) is the coldest part of central Portugal, with regular winter snow and cool summers.

The Interior: Alentejo, Beira, and Trás-os-Montes

The Portuguese interior is the climate that no travel brochure prepares you for. It is also the most extreme, with the largest temperature swings between summer and winter, the lowest rainfall, and some of the hottest summers in Europe.

Alentejo (Évora, Beja, Portalegre, Moura): Hot, dry, continental. Summer highs of 35–42°C are normal from late June through early September, with occasional peaks above 44°C. Winters are cool (3–13°C) with light frost. Annual rainfall is 400–600 mm, concentrated between October and April. The landscape is the rolling golden plains of cork oaks and olive groves that you see in photos. The Alentejo coast (around Sines and Vila Nova de Milfontes) is significantly cooler and breezier, more like the Silver Coast.

Beira Interior (Guarda, Castelo Branco): The coldest inhabited region of mainland Portugal. Guarda is one of the highest cities in Portugal (1,056 m) and regularly sees snow from December to March, with January lows of -3 to -5°C. Summer is warm but not extreme (26–30°C highs), and the mountain landscapes are spectacular. Castelo Branco is warmer in summer (35–40°C) and milder in winter.

Trás-os-Montes (Bragança, Mirandela, Chaves): Continental climate with long cold winters (regular snow, -5 to -8°C lows) and hot dry summers (30–38°C). The annual temperature swing is the largest in Portugal. Annual rainfall is 600–900 mm. The region is sparsely populated, beautiful, and very affordable — but the climate is unforgiving if you are not used to it.

Madeira

Madeira has the most consistently mild climate in Portugal — subtropical, moderated by the Atlantic, with very small temperature variation between summer and winter. It is the climate that some expats describe as "eternal spring."

The north coast of Madeira is significantly wetter than the south (Funchal) — annual rainfall of 1,000+ mm vs 500–600 mm in Funchal. The mountains are wetter still, with laurel forests and frequent mists. Microclimates are extreme: Curral das Freiras (a valley in the mountains) is one of the driest inhabited places in Madeira, while Monte is often shrouded in cloud. Sea temperatures are swimmable 12 months a year (lowest around 17–18°C in February–March, highest around 22–23°C in August–September). For the deep dive, see our Madeira living guide.

The Azores

The Azores have an oceanic climate — cool, wet, and four-season, similar to the UK or Ireland but milder. They are not for expats who want warm dry summers and Mediterranean weather, but they are excellent for those who want green landscapes, mild temperatures year-round, and a low-density lifestyle.

The Azores get roughly 1,000–1,600 mm of rain per year, depending on the island. Santa Maria is the driest and sunniest (often called the "yellow island" for its drier landscape), with annual rainfall below 800 mm. Flores is the wettest, exceeding 2,000 mm. The central group (Terceira, São Jorge, Pico, Faial) is balanced. The north sides of all islands are wetter than the south sides. The Azores are also on the edge of the Atlantic hurricane belt; named storms typically pass within a few hundred kilometers between August and October, bringing strong winds and high surf. For the deep dive, see our Azores living guide.

How to Choose the Right Climate for You

Most expats choose a region based on one of three priorities:

If you want the warmest, driest, sunniest mainland climate: The eastern Algarve (Tavira, Vila Real de Santo António) or the Alentejo coast. Both deliver 3,000+ sunshine hours per year, mild winters, and dry summers. The eastern Algarve is the most consistently "summer" climate in Portugal. The Alentejo interior is more extreme — hotter in summer, colder in winter, drier overall.

If you want the mildest year-round climate with minimal temperature variation: Madeira, especially the south coast (Funchal, Câmara de Lobos). Average temperatures range from 14–20°C in winter to 19–28°C in summer. The sea is swimmable all year. Rain is concentrated between October and March.

If you want four seasons with green landscapes and mild extremes: The Azores, or the Silver Coast, or northern mainland Portugal. All have cooler summers, milder winters, and more rain than the south. None are extreme. The Azores are the most consistently "mild" — no region of Portugal has a more balanced climate.

If you want a balance of city amenities, beach access, and good weather: Lisbon, the western Algarve, or Coimbra. All offer culture, infrastructure, healthcare, and reasonable weather. Lisbon is the obvious choice for most expats — the climate is excellent, the city is world-class, and the rest of the country is a short flight or drive away.

Whatever you choose, visit in at least two seasons before committing. The expats who regret their choice are almost always the ones who rented or bought sight-unseen based on a summer visit, then discovered that the climate they bought was a fair-weather illusion.

FAQ: Weather in Portugal

What is the best month to move to Portugal?

For most expats, the best months to move to Portugal are April, May, September, and October. Spring (April–May) and early autumn (September–October) offer mild temperatures (18–25°C), minimal rain, and a working rental market. Avoid July and August if you are renting from abroad — landlords and agents are slow, the heat is intense (especially in the interior and the Algarve), and the most desirable apartments are often already taken by summer visitors. January and February are also viable, with lower rental prices and the fewest tourists, but expect rain (especially in Porto and the north) and short days.

Where in Portugal has the best weather year-round?

The Algarve has the most consistent year-round weather in mainland Portugal, with around 3,000 sunshine hours per year, mild winters (10–17°C), and warm dry summers (24–30°C). The eastern Algarve (around Tavira and Vila Real de Santo António) is even drier and sunnier than the western Algarve. Madeira is the warmest island destination, with subtropical temperatures (17–26°C) all year and minimal temperature variation between summer and winter. For most expats who prioritize sun and mild winters, the Algarve or Madeira deliver the best year-round experience. The Azores are mild but rainy in winter; Lisbon and Porto have pleasant summers but cool, wet winters.

Is Portugal hotter than Spain or Italy?

In summer, Portugal's interior and the Algarve are roughly comparable to southern Spain and central Italy for peak temperatures (often reaching 35–40°C in July and August). On the Atlantic coast (Lisbon, Porto, the Silver Coast, the western Algarve, and the Azores), Portugal is significantly cooler than the Mediterranean — summer highs of 25–28°C are normal, with cooler sea breezes. In winter, Portugal is milder than most of Spain and central/northern Italy — Lisbon rarely drops below 5°C, while Madrid, Rome, and Milan see frequent frost. Portugal's Atlantic moderation gives it warmer winters and cooler summers than Mediterranean countries at the same latitude.

Does it snow in Portugal?

Snow falls every year in the highest mountains of northern and central Portugal — the Serra da Estrela (highest point 1,993 m), the Gerês mountains, and the Montesinho. In these areas, snow is heavy enough to support a small ski season (December to March) at the Serra da Estrela ski resort, the only one in Portugal. Outside the mountains, snow is rare. Lisbon sees a light dusting once every 5–10 years. Porto sees snow once every 3–5 years, usually a brief flurry that melts within hours. The Algarve essentially never sees snow. Madeira's highest peaks (Pico Ruivo, 1,862 m) get occasional snow in winter. The Azores essentially never see snow except on the Pico volcano (2,351 m) on rare occasions.

How rainy is Porto compared to Lisbon?

Porto is significantly rainier than Lisbon. Porto receives about 1,450 mm of rain per year spread across roughly 150 rain days, while Lisbon receives about 750 mm across 100 rain days. Porto's rain falls mostly between October and April, often as persistent drizzle or Atlantic storms. Lisbon's rain is more concentrated — long dry periods broken by intense autumn and winter downpours. The north of Portugal generally (Minho, Douro, Trás-os-Montes) is the wettest part of the country, with annual totals exceeding 1,800 mm in some areas. The driest mainland region is the eastern Algarve and the Alentejo, with annual rainfall below 500 mm.

What is the hottest part of Portugal?

The hottest part of mainland Portugal is the interior Alentejo and the upper Douro/Sabor valleys in the northeast, where summer temperatures regularly exceed 40°C and several days per year cross 43°C. The Alentejo cities of Évora, Beja, and Moura, and the Beira Interior (Castelo Branco, Portalegre) record the highest mainland temperatures. Among inhabited areas, the Ribatejo (around Santarém) also sees extreme summer heat. The Algarve is hot but moderated by the Atlantic, with summer highs typically 28–32°C. The hottest islands are Madeira (32–35°C in Funchal in late summer) and Santa Maria in the Azores (28–30°C peak). For context on the cities where this heat plays out, see our Lisbon neighborhoods guide and Porto neighborhoods guide.

When is hurricane season in the Azores?

The Azores lie on the northern edge of the Atlantic hurricane belt. The official Atlantic hurricane season runs from June 1 to November 30, with peak activity in August and September. The Azores are typically affected by the post-tropical remnants of hurricanes that have curved north and weakened — most years, the islands see one or two named storms pass within a few hundred kilometers between August and October, bringing strong winds, heavy rain, and high surf. Direct hurricane landfalls are rare (the most recent significant ones were Hurricane Lorenzo in 2019 and Hurricane Gabrielle in 2025). Expats living in the Azores should have a basic storm plan, follow IPMA (the Portuguese weather service) alerts, and avoid coastal properties vulnerable to high surf during the autumn months.
