Four Seasons in One Day: The Meteorological Phenomenon of the Azores
The Azores are famous for a saying that any visitor quickly comes to understand: “If you don’t like the weather, wait five minutes.” This popular phrase perfectly sums up the unpredictable and fascinating nature of the Azorean climate.
The Azores High
The main player in the climate not only of the archipelago but of all Western Europe is the Azores High — a vast semi-permanent area of high atmospheric pressure centered in the North Atlantic. This system influences air currents and determines weather patterns from Scandinavia to North Africa.
When the high-pressure system is well positioned over the islands, the days are marked by clear skies and mild temperatures. However, when it shifts away, it leaves room for Atlantic fronts and low-pressure systems to bring heavy rain, wind, and fog within a matter of hours.
Island Microclimates
Each island has its own microclimates. In São Miguel, it is possible to enjoy bright sunshine in Ponta Delgada while heavy rain falls in Sete Cidades, just 30 km away. The central mountains act as natural barriers that condense air moisture, creating thick fog at higher elevations while the coastline remains clear.
Mild Temperatures All Year Round
One of the great advantages of the Azorean climate is its mildness. Temperatures rarely drop below 10°C in winter or exceed 28°C in summer. This thermal stability is due to the moderating influence of the Gulf Stream, which keeps the waters of the North Atlantic relatively warm.
