The best time to visit Portugal, and the month everyone underrates
The best time to visit Portugal by region and month, with the June festivals worth planning around and the city taxes that doubled and then stopped.

Portugal's answer is unusually clear and almost everybody arrives in the wrong month anyway. September is the best time to visit Portugal, with May and June just behind it and better for different reasons.
July and August are the months to avoid unless the school calendar decides for you, and even then the coast is a better bet than the cities.

The Atlantic is the reason. Portugal's sea is cooler than its latitude suggests, because of the current running down the western coast, and it takes the whole summer to warm up.
So the water is at its warmest in late August and September, not in June. September gives you that warm sea, air temperatures in the mid-twenties, and a country that has emptied out because the Portuguese and Spanish school holidays have finished.
Prices start falling in the second week of September and keep falling through October.
The only thing you lose is a couple of hours of daylight against midsummer, and the festival calendar, which is June's.
Month by month
January and February. Mild in Lisbon and often bright, wet in Porto and the north, and the cheapest rooms of the year. The cities work; the Algarve does not. Madeira is at its most reliable warm-winter destination.
March. Improving, unpredictable, and increasingly busy at the end if Easter falls early.
April. Green, flowering, and genuinely lovely inland. The sea is still cold. Good for walking, cycling and the Douro.
May. One of the two best months. Warm days, long light, everything open, sea still cold. Excellent for the cities and the interior.
June. The best month for the cities, and it is a festival month, which is below. Warm without being hot.
July and August. Hot, full and expensive. The interior and the Alentejo get genuinely severe, the Algarve is at capacity, and Lisbon and Porto are busy in a way that costs you the thing you came for. If you must come now, go to the coast rather than the cities, and pick the wilder west coast over the Algarve's southern strip.
September. The best month overall. See above.
October. Still warm through the first half, quiet, cheap, and the best light of the year for the Douro, where the harvest has just finished.
November and December. Wet in the north, mild in the south, and Lisbon is a very good cheap city break. Funchal's New Year fireworks display in Madeira is one of the largest anywhere.
The June festivals, which are worth planning a trip around
The Santos Populares run through June and they are the best thing in the Portuguese calendar.
Lisbon's Festa de Santo António fills the Alfama and Mouraria with grilled sardines, paper decorations and street parties, peaking around 12 and 13 June.
Porto's Festa de São João is on the night of 23 June and is one of the great street parties of Europe: the whole city out, grilled sardines, bonfires, fireworks over the Douro at midnight, and a tradition of hitting strangers on the head with a small plastic hammer, which sounds alarming and is entirely good-natured.
Book accommodation months ahead for São João, because Porto genuinely fills. Portugal's meteorological institute publishes the climate normals if you want the month-by-month numbers behind any of this.
The regional differences that matter
The Algarve is the warmest and most reliable, with the mildest winter in mainland Europe. May, June and September are its best months, and August is when everyone else is there.
Lisbon is mild year-round and windy. Its summer is hot but coastal, so it is more bearable than Seville or Madrid at the same time of year.
Porto and the north are noticeably wetter. Porto is best between May and October, and its winters are wet and chilly rather than cold.
The Alentejo, the interior, is the hot one. Summer inland regularly passes what is comfortable and the spring and autumn are the seasons for it.
Madeira runs its own calendar entirely: mild all year, warmest August to October, and the best walking destination in Portugal in months when the mainland is too hot for it.
What it costs, and the taxes that stopped rising
Portugal's city taxes went up sharply and then stopped, which is unusual in Europe right now.
| Per person, per night | |
|---|---|
| Lisbon | €4, capped at 7 nights |
| Porto | €3, capped at 7 nights |
| Algarve | €1 to €2, seasonal |
| Madeira, including Funchal | €2, capped at 7 nights |
Lisbon doubled from €2 on 1 September 2024 and Porto rose from €2 in December 2024. Neither has announced a further increase for 2026, which makes Portugal cheaper on this line than Spain's Catalonia, Amsterdam or Milan. Portugal's national tourism board keeps the regional practicalities, and the taxes are set municipally.
Room rates follow the season hard. A Lisbon or Algarve room in September against the same room in August is a materially different number, and it is the largest single saving available on a Portuguese trip.

Everything we check for Portugal →Picking a month for a specific trip
A beach holiday: September first, then June, then late May.
A city break: June for the festivals, or January and February for the prices and the emptiness.
The Douro valley: late September and October, after the harvest, when the terraces turn and the light is at its best.
Walking, cycling or the interior: April, May and October. Not July or August.
Surfing: autumn and winter on the west coast, which is when the swell arrives and when the water is still warm enough from the summer.
Madeira: almost any month, and April to June for the flowers.
Portugal in 10 days is the route these months apply to.
What to skip
August in Lisbon or the Algarve, if you have any flexibility at all.
The Algarve between November and March as a beach destination.
Porto over São João without a booking made months ahead.
Assuming the sea is warm in June. It is not, and it is a common disappointment.
Judging Portugal's weather by Spain's. The Atlantic makes it cooler, wetter in the north and far more windswept.
Before you book
Portugal in 10 days is the route, Lisbon or Porto is the choice most people are making, and two days in Porto and three days in Lisbon are the two cities. Where to stay in Lisbon and where to stay in Porto have the neighbourhoods, and day trips from Lisbon covers Sintra and the coast. The best time to visit Spain is the neighbour's version of the same question, with a very different answer.
The Lisbon city guide and the Portugal country guide carry the practicalities, and there is more in the when to go hub.
Tax rates and festival dates checked September 2026. Portuguese city taxes are set municipally and the June festival programmes are published each spring, so the individual city's own tourism office is the place to confirm rather than any guide, this one included. Here is how we research and re-check guides.
