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 April feels like
April is warm without being hot and the island is at its greenest. Sea breezes keep the coast comfortable and the evenings no longer need a heavy layer.
What to pack
Light clothing with one warm layer, walking shoes, and sun cream. The UV is stronger than the temperature suggests.
What to do in April
Whale and dolphin watching gets going as the migrating baleen whales pass, and this is the best month of the year for the long trilhos, before the summer haze settles in. The hydrangea hedges are still bare; they come out in July.
Worth knowing before you book
Easter is the busiest week of the spring for hotels and hire cars, so book early. Showers still pass through, usually briefly.
Quick answers
- How warm is it in the Azores in April?
- In Ponta Delgada an average April day reaches 20 °C and falls to 14 °C overnight. The summit of Mount Pico averages 9 °C in the same month, so the mountain needs its own layer.
- Can you swim in the sea in April?
- The sea averages 17 °C in April. 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 April?
- About 13.0 hours between sunrise and sunset, which sets how much of a long trilho you can fit in before dark.
