Azores weather in April

April brings mild days and cool nights at these seven stations. Average night lows sit close to 13 °C. Ponta Delgada's average high rises 0.9 °C from March. It remains 7.2 °C below August's.

The spread between the stations' average highs is only 1.6 °C. I'd give activities more weight. The temperature differences are small. For warmer spring days, consider May. Ponta Delgada's average high rises another 1.4 °C that month.

April has less rain than March at all seven stations. Ponta Delgada's monthly average falls by 18%. It is still about three times July's. Flores Airport's average falls by roughly one third from March.

Ponta Delgada averages 10.2 days with at least 1 mm of rain. That includes 2.4 days with 10 mm or more. A rain day measures the daily rainfall total. It does not mean rain from morning to night. Keep the order of outdoor plans flexible.

Santa Maria Airport has the lowest April rainfall among these seven stations. Santa Cruz da Graciosa comes next. Flores Airport has the highest total. Its average is almost twice Santa Maria Airport's.

I'd consider Santa Maria if avoiding rain matters most. Ponta Delgada, Angra and Horta have very similar totals. These are records for individual stations. Their reference periods differ. They cover different sets of years. Keep a wet weather plan whichever island you choose.

You can swim in April, with sea temperatures averaging about 16 °C. I'd choose a thermal pool for warmth. Terra Nostra in Furnas has water at 38 to 42 °C.

Vila Franca Islet's 2026 bathing season was scheduled for 12 June to 11 October. That put April outside the season. I'd choose summer for a trip centred on sea swimming. August's sea average is about 22 °C.

April suits whale watching and walks between wet spells. Blue whales and fin whales pass the Azores during spring migration. I'd book whale watching early in your stay. Unsafe weather cancels boat departures. Leave time to try another date.

Check trail status before choosing a walk. We refresh the regional alerts twice a day. Read the forecast too. Choose a route that suits your fitness. Follow the marked route.

Pack a waterproof jacket and walking shoes with good grip. Bring a warm layer for evenings. Take it on boat trips too. Use layers you can remove while walking. Add a hat and sunscreen for time outdoors. I'd keep spare socks dry in your bag.

Bring a dark swimsuit for Terra Nostra. Iron in the water can stain pale fabric. Rinse swimwear before it dries. I'd also pack a towel and dry clothes for afterwards.
