São Miguel is called the Island of the four seasons because now it rains, sometimes it gets warm
The archipelago is spread out in the area between 37° N and the parallels of latitude that pass through the Lisbon area (38° 43' / 38° 55' N), giving it generally a tepid, oceanic, subtropical climate, with mild annual oscillations. Daily maximum temperatures usually range between 15 and 25°C (59 and 77°F). The average annual rainfall increases from east to west, and it ranges from 700 to 1600 annual millimetres (27.6–63 in) on average, reaching 6.3mm (250 in) at Mountain of Pico (Pico Island), the highest Portuguese mountain at 2.351m (7.713ft).

The Azores High, an area of high atmospheric pressure, is named after the islands. Under the Köppen climate classification, there are different local climates, one of it is "dry-summer subtropical", often referred to as "Mediterranean".
Rivas Martinez data presents several different bioclimatic zones for the Azores Seasonal lag is extreme in the low-sun half of the year, with December being milder than April in terms of mean temperatures. Azores have the warmest winters in Europe (still within the European continental plate).
During summer, the lag is somewhat lower with August being the warmest month. There has never been a frost, snowfall or freeze ever recorded at sea level on any of the islands. The coldest weather in winter usually occurs in a north-westerly air mass with its origins from Labrador in Canada, but even then due to its passage across the warmer Atlantic Ocean still allows temperatures by day even then to exceed 10°C.
