Best time to visit Pico: weather by month, the mountain, whales and festivals

The question behind "when should I go to Pico" is usually a narrower one: when can I climb the mountain, and what else will be on? For most people the answer is June to September. The mountain house is open around the clock, the coast is at its driest, the summer ferries are running and the sea is warm enough to swim. Come in March or April if the big migrating whales matter more to you than swimming. Winter has its own guide.

At sea level Pico is mild all year. The figures below are long-term averages for Pico Airport, on the north coast near Madalena.

• Daytime highs run from about 16 °C in February to about 25 °C in August. Summer nights stay at 16 to 20 °C.
• July is the driest month, with about 31 mm of rain, and June is close behind at about 36 mm. August gets about 63 mm.
• Rain picks up again in September (about 91 mm) and October (about 131 mm). November and December are the wettest months, with around 145 mm each.
• Humidity sits around 80 percent in every month, summer included.

The middle of the island is a different place. A weather station at Cabeço do Teicho, about 850 metres up on the plateau, recorded summer highs of only about 20 °C between 2017 and 2024. It also logged more rain in July (about 106 mm) than the airport gets in any month from April to September. That is why the road across the lakes can be in cloud on a day when Madalena is in sunshine. If the plateau or the mountain is your goal, check the sky in the morning and be ready to swap days.

Every climb of Mount Pico starts at the Casa da Montanha, at about 1,200 metres, where you register and collect a GPS tracker. Under the access regulation (Portaria 64/2023) its hours follow the season:

• 1 May to 30 September: open all day and night.
• April and October: open continuously from 08:00 on Friday to 20:00 on Sunday, and from 08:00 to 20:00 on the other days.
• 1 November to 31 March: 08:00 to 18:00.

From May to September you can start at any hour, including before dawn if you want to reach the summit for sunrise. Overnight climbs, with a night in the crater, are limited to 32 people a day and have to be reserved at least 24 hours ahead. From June to September they start between 16:00 and midnight.

Summer has its own risk: there is no shade on the way up, so start early and carry more water than you think you need. Fees, the tracker and the rules on weather warnings are in our guide to climbing Mount Pico.

Pico has 26 official bathing areas in 2026, most of them rock pools and concrete platforms in the lava rather than sand. They have lifeguards only from June to September. The sea is about 16 °C from January to April, around 19 °C in June and 22 to 23 °C from July to September. It is still about 21 °C in October, which makes early autumn a good time for a swim if the swell allows it. Our swimming guide lists the pools by town.

Boats go out from Lajes do Pico all year, weather permitting, so there is no wrong month for whale watching. What changes is what you are likely to see.

• In spring, and especially March and April, blue, fin and sei whales pass the island on their way north. One Lajes operator also names humpbacks in those months.
• In summer, sperm whales and some baleen whales are frequent, and spotted dolphins join the common and bottlenose dolphins that live here all year.

If seeing a blue whale is the reason for the trip, go in March or April. If you want a boat trip and a swim on the same day, go in summer. See whale watching from Lajes do Pico.

The Faial crossing between Horta and Madalena runs all year, but the rest of the timetable is seasonal. In summer 2026 Atlânticoline ran:

• extra Horta-Madalena sailings from the second half of June;
• the Linha Verde, two connections a day between Pico, São Jorge and Faial;
• the Linha Laranja between São Roque do Pico and Velas on São Jorge, from 15 June to 15 September, at least twice a day except on Wednesdays and Thursdays;
• the Linha Branca on Mondays and Fridays and the Linha Lilás on Tuesdays and Saturdays, both from June to September, linking Pico with Graciosa and Terceira.

The summer timetable ended with September. In winter 2026/27 the Faial line drops to four return sailings a day, and the São Jorge line to two a day on Mondays, Wednesdays and Fridays and one on other days. If you want to reach Terceira or Graciosa by boat, plan for summer. The timetable is set again every year, so check atlanticoline.pt for your dates.

Pico's main summer events of 2026 fell between mid-July and the end of August, one after another in different towns.

• Festas da Madalena, Madalena: 17 to 22 July 2026, for Santa Maria Madalena, the town's patron saint, with religious celebrations and evening concerts.
• Cais Agosto, São Roque do Pico: 29 July to 2 August 2026, five days of music.
• Bom Jesus Milagroso, São Mateus: the pilgrimage fills the first days of August and peaks on 6 August, with the faithful coming over from other islands.
• Semana dos Baleeiros, Lajes do Pico: 24 to 30 August 2026, the whalers' week, with music, sport and the town's whaling traditions.

Dates move a little from year to year, so check the municipal sites in spring. If your trip overlaps one of these weeks, book your room in that town early. If you want quiet evenings, stay in another town that week.

• January to March: mild on the coast, wet and often in cloud higher up. The mountain house opens only from 08:00 to 18:00. See Pico in winter.
• April: with March, the best time for blue whales. The mountain house keeps longer hours from Friday to Sunday. Only the year-round ferry lines run.
• May: rain is easing and the mountain house is open around the clock from the 1st. The sea is cool at about 17 °C.
• June: one of the two driest months, with the summer ferries starting and the lifeguards on duty. A strong choice for a first visit.
• July: the driest month. Madalena's festival falls in the second half, and in 2026 the Gruta das Torres lava tube reopened on 19 July after two years closed.
• August: the warmest month, with the most going on: Cais Agosto, the Bom Jesus pilgrimage and the whalers' week. Book ahead.
• September: the sea is still at its warmest, the summer ferries run to the end of the month, and rain starts to come back.
• October: the sea is still about 21 °C, but rain is heavier and the mountain house shortens its hours again.
• November and December: the wettest months, with short days and one ferry line to São Jorge.

What is the best month to visit Pico? June or July for most visitors. They are the driest months at sea level, the Casa da Montanha is open around the clock, and the summer ferries and the lifeguards are running.

When is the best time to climb Mount Pico? From May to September, when the Casa da Montanha is open 24 hours and you can start before dawn. Pick a clear morning and start early, because there is no shade on the way up.

When can you see blue whales from Pico? In spring, mainly March and April, when blue, fin and sei whales pass the island on migration. Sperm whales can be seen all year and are frequent in summer.
