Météo à Ponta Delgada (Azores) en septembre

September has become the month Azores regulars name: ocean around 23C, air around 25, and drier than midsummer - our row gives 24.6C and a 23.6C sea. What they never stop saying is that the weather here changes inside a day and can produce several kinds of it before evening, with a storm possible in any month; our row's 10.2 precipitation days at 25 kph is that Atlantic restlessness. September also sits at the back end of the whale season, which runs roughly May to September for the big migrating whales, though sperm whales and dolphins are there year-round and the boats leave from the waterfront in the middle of town. The record: 19.7C nights, 51.8mm of rain, humidity 78 percent and 10.8 hours of sun.

Regulars are specific a rain jacket is mandatory here regardless of forecast, the weather capable of running through what feels like all four seasons in a single day, with Ponta Delgada's own south-coast position making it warmer and sunnier than locations on the north coast of the same island. Our row backs that cool, genuinely wet and windy read, 19.5C over 15.1C nights feeling 13C, with a substantial 71.9mm of rain across 11.3 days and a real 27.6 kph wind. Regulars are honest that statistically September reads as a better month than this one, though late May and June both still count as genuinely good windows to visit. A warm layer for evenings alongside the rain jacket remains the standard advice throughout. The sea sits at a cool 18.6C. The record: 11.7 hours of sun, humidity 81 percent and AQI 47.

The phrase this board reaches for is four seasons in one day, and it means it: the weather changes constantly, the showers are intermittent, they may miss half the island and may not fall in daylight at all. June is among the better months - regulars list June through September as the driest and warmest - and our row is gentle rather than dramatic: 21.7C by day and 17.2C at night, a four-and-a-half degree range, which is what mid-ocean does to a climate. Rain is 38.4mm across 6.7 days, so the showers really are quick. The constant is wind, 24.1 kph, and the sea is 20.4C. A waterproof shell you can take off again. The record: humidity 81 percent, 12.6 hours of sun and AQI 46.

Ponta Delgada-forum threads on April weather agree it's one of the better months to visit, but every account leans hard on unpredictability as the defining feature: one visitor's third week of April brought genuinely sunny, lovely conditions on the main island, while other islands in the same archipelago saw wind, rain and even hail on the very same days. The standing advice is short sleeves layered under a light waterproof jacket, since a clear morning can turn to rain within the hour, and fog is common enough to factor into hiking or viewpoint plans. Posters say flexibility matters more here than in most destinations - build slack into any day trip, since a washed-out morning can still turn into a beautiful afternoon. Despite the variability, regulars call April one of the calmer, less rain-prone stretches of the year overall. The record: 17.9C days feeling like 16C, 13.7C nights, 80mm across 12.5 days, a 17.1C sea, 80 percent humidity and wind averaging nearly 33 km/h.

July and August are the driest and warmest months on São Miguel without being hot, and the Azores forum's caveat is variability rather than averages: the weather here changes several times in a day, cloud mixed with sun is the norm, and different parts of the island run their own microclimates - what Ponta Delgada is doing is not what the north coast is doing. Humidity is noticeable in summer, and more than one regular reports rain almost every day of a visit that fell mainly overnight. Layers, and no fixed plan for any given morning. The record: 26C days feeling like 28C, 20.5C nights, 6.8 precipitation days, 12 hours of sun, a 24.1C sea and a 21 kph wind.
