Weather in Madeira in August
A monthly average blurs the two Madeiras together: a drier south, a wetter and greener north. The numbers below are the island averaged out. On the day you actually walk, one coast is clear and the other is under cloud.
August is the hottest, driest, busiest month. On the coast expect highs near 28 °C; a few times a summer the leste, a hot dry wind off the Sahara, pushes temperatures well past that for a day or two.

Why Madeira's weather differs by coast and altitude
The three rows above are the point: in the same August week, Funchal and the summits behave like different countries. Madeira's mountains split every weather system in two, so "weather in Madeira" is really the weather of whichever coast and altitude you stand on. The pattern is explained in our microclimate guide; for a specific day, live per-trail conditions beat any monthly average.
Hiking in Madeira in August
Altitude is the escape. The summits average a pleasant 16 °C, the forest walks are shaded, and dawn starts put you on the trail hours ahead of the crowds and the heat. Carry more water than feels necessary; levada water is not for drinking.
Good starting points this month: summit hikes and forest & laurisilva trails. Regulated classics like PR1 need advance booking via SIMplifica.
What August is like in Madeira
The warmest sea of the summer so far, the busiest trailhead car parks of the year, and the month where booking the regulated classics ahead stops being optional in practice.
Common questions
How warm is Madeira in August?
On the south coast around Funchal, August days average about 27.6 °C and nights about 20.7 °C. The mountains are a different world: at Pico do Arieiro (1,818 m) the average daytime high is around 16.3 °C. Pack for both if you plan to hike high.
Does it rain a lot in Madeira in August?
Funchal averages roughly 11 mm across about 3 rainy days in August, one of the driest months on the south coast. The north coast and the mountains always catch more. Rain is usually local: when one coast is wet, the other is often dry, which is why a single island-wide forecast misleads.
Can you swim in the sea in Madeira in August?
The Atlantic around Funchal averages about 24.9 °C in August, which is comfortably warm for swimming. The natural lava pools at Porto Moniz and Seixal are the classic post-hike swim spots.
Is August a good month for the levada walks?
Yes. Levada walks work all year because most sit in sheltered valleys and forest, and Madeira has no real off-season. What changes in August is which side of the island has the better day, so check live per-trail conditions on the morning rather than trusting a single island-wide forecast.
