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 October feels like
October is mild and increasingly changeable. The sea holds its summer warmth well into the month while the sky starts doing considerably more.
What to pack
Layers again, a waterproof shell, and swimwear that will still get used. Walking shoes with grip, because wet basalt is slick.
What to do in October
Swimming and walking both still work, and the low light is good for photography. The whale watching season winds down, and the crater lakes are at their best between showers.
Worth knowing before you book
Heavy rain days become normal and trails can close at short notice. Wind picks up, and the inter-island flights start to be cancelled or diverted.
Quick answers
- How warm is it in the Azores in October?
- In Ponta Delgada an average October day reaches 24 °C and falls to 19 °C overnight. The summit of Mount Pico averages 13 °C in the same month, so the mountain needs its own layer.
- Can you swim in the sea in October?
- The sea averages 22 °C in October. 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 October?
- About 11.4 hours between sunrise and sunset, which sets how much of a long trilho you can fit in before dark.
