Temperature and daylight, averaged over the ten years from 2016 to 2025 and recomputed from the Open-Meteo archive rather than typed in by hand. The model works in cells roughly ten kilometres across, so each column describes an area rather than one thermometer. Checked against IPMA's Ponta Delgada normal, the temperatures land within about a degree and a half. Sea temperature averages the years 2022 to 2025. The marine record is shorter than the air record, so it rests on fewer years.
What August feels like
August is the warmest month by day and by night, and the sea is at its warmest too. Coastal evenings stay balmy enough to eat outside without a layer.
What to pack
Summer clothes, swimwear, sun protection and something light for the evening. Nothing heavy unless the summits are planned.
What to do in August
The Assumption holiday on 15 August fills the north coast towns. Sea pools, boat trips and early-morning high routes are all in their element.
Worth knowing before you book
It is the busiest month for hotels, flights and hire cars, and the popular trails need an early start to be worth it. Heat and dry vegetation raise the wildfire risk, which occasionally closes paths at no notice.
Quick answers
- How warm is it in the Azores in August?
- In Ponta Delgada an average August day reaches 28 °C and falls to 21 °C overnight. The summit of Mount Pico averages 17 °C in the same month, so the mountain needs its own layer.
- Can you swim in the sea in August?
- The sea averages 25 °C in August. The Azores sit in open ocean with no shallow shelf to warm the water, so it stays close to that figure all month.
- How long are the days in August?
- About 13.3 hours between sunrise and sunset, which sets how much of a long trilho you can fit in before dark.
