When to visit Portugal, month by month.
Keyed to the circuit most operators sell: Lisbon + Porto + Algarve + Sintra. For the best all-round experience, go Sep/Jun. For the lowest prices and thinnest crowds, go Jan-Feb.
Two windows, because they answer different questions. Best experience scores the weather, the headline sights and low crowds; cheapest and quietest scores only airfare and how empty it is. Special-interest seasons (skiing, Christmas markets, aurora, festivals) are kept out of the experience score and flagged on their own line, so a niche winter draw never masquerades as the best all-round month. If you care most about one thing, read that column below.

What each month actually gives you
January is the value sweet spot for cities and the Nazare big-wave show, but it is Portugal's wettest stretch and the Algarve coast is effectively shut.
February stays cheap, quiet and wet, with Carnival (13-17 Feb 2026) as the one big draw and Nazare still firing.
March is the turn of the season: cities warm up nicely and stay uncrowded, though the sea is still cold and Porto still rains.
April is one of the best all-round city-and-culture months: mild, green and pre-peak, though beaches remain a brisk-swim affair.
May is arguably the single best month overall: warm, dry, green and still short of the July-August crowd-and-price peak.
June brings hot dry days, warm-enough beaches and the country's biggest street parties (Santo Antonio in Lisbon, Sao Joao in Porto), just as crowds and prices start climbing.
July is peak summer: dependable heat and beaches plus NOS Alive festival, but it is the most crowded and expensive window and the cities bake.
August delivers the warmest sea and guaranteed sun, but it is the absolute peak for crowds and Algarve hotel prices, and the heat is relentless.
September is the connoisseur's pick: warm dry weather, the warmest sea of the year, the Douro grape harvest, and crowds and prices finally easing.
October is the last of the warm shoulder: golden Douro colour and Nazare's opening giants, with the trade-off that autumn rain returns, hard in Porto.
November is cheapest and emptiest and prime Nazare-giant time, but it is also Portugal's wettest month, brutally so in Porto, and the Algarve is shutting down.
December splits in two: cheap, quiet, festive cities early in the month, then a Christmas and New Year airfare spike, all under wet winter skies with Nazare still firing.
Worth noting
- • Porto is genuinely, measurably wetter than Lisbon: 1,146.9mm of rain over about 105 rain days a year versus Lisbon's 793.5mm over about 75 days. A Porto-heavy itinerary needs a rain plan even in shoulder season.
- • Porto's wettest month is November (165.9mm), not the depth of winter, and December (153.3mm) and January (151.0mm) are close behind. The autumn-into-winter shoulder is the rainiest window in the north.
- • Nazare's famous 20-to-30-metre waves are a WINTER product (October to March, biggest November to February). Turn up in July and you will find a calm beach; the big-wave surfers and the WSL tow challenge are a cold-season show.
- • Sintra's Pena Palace now runs on timed-entry tickets that must be booked online with a specific date and time slot, and they routinely sell out in peak season. Turning up on spec in July or August risks being turned away.
- • Lisbon in July and August is almost rainless (July averages just 2.6mm over well under one rain day) and hits about 28-29C, while the Alentejo interior can top 40C. The dryness is a feature; the inland heat is the hidden cost.
- • The Algarve is Atlantic, not Mediterranean: even at its August-September warmest the sea only reaches about 20-21C, cooler than many Indian travellers expect from a European beach holiday, and it is genuinely cold (15-16C) November to March.
- • The tourist-tax rates have risen recently and are per person per night: Lisbon is now EUR 4 (doubled from EUR 2 in September 2024) and Porto is EUR 3 (raised from EUR 2 in December 2024), each capped at 7 nights. A family stacks this up fast; children under 13 are typically exempt.
- • The Douro grape harvest (vindima) is a mid-September to mid-October event, not an all-autumn one, and some working quintas actually reduce tourist visits while picking is underway. The Festa da Vindima at Peso da Regua is 18-20 September 2026.
- • June is the street-party peak: Lisbon's Santo Antonio centres on the night of 12-13 June (13 June is the city holiday) and Porto's Sao Joao on 23-24 June (24 June is Porto's holiday). Great atmosphere, but rooms in those cities tighten around the dates.
