The climate of the Azores Islands is subtropical oceanic, cool or mild for many months and pleasantly warm in summer; therefore, they are not a tropical paradise. The archipelago, a Portuguese autonomous region, is located in the Atlantic Ocean at the same latitude of the Mediterranean Sea, but the influence of the ocean makes the climate even milder, especially in summer, when the temperature is lower than on the coasts and islands of the Mediterranean Sea.



The winter temperatures range from 11/12 °C (52/53 °F) at night to 17/18 °C (63/64 °F) during the day, while in summer, they range from 17/18 °C (63/64 °F) at night to 24/26 °C (75/79 °F) during the day. The temperature varies slowly from a month to the other, and highs exceed 20 °C (68 °F) only from June to October. The highest temperatures on the Azores are not impressive: they almost never reach 30 °C (86 °F) even in summer. On the other hand, temperatures rarely drop below 7/8 °C (45/46 °F) in winter.
Here are the average temperatures of Ponta Delgada.

The Azores gave their name to the famous anticyclone (high-pressure area) that brings fine weather on Western Europe and the Mediterranean (i.e. the Azores High), however, on these islands the weather is not always sunny. In fact, in autumn and winter, the rains are frequent, and on the north-western islands, they are also abundant.
Owing to the abundance of rainfall, the landscape is green and in bloom; flowers paint the landscape mainly in spring and gave their name to the westernmost and very rainy island of Flores ("flowers").
Here is the average precipitation of Santa Cruz, on the island of Flores.

The rainfall doesn't reach 800 millimeters (30 inches) per year on the island of Santa Maria (the southeasternmost island), it's just above this value in Santa Barbara, while it exceeds 1,000 mm (40 in) on the other islands. In the summer months, from June to August, the rains are a bit more rare and less abundant, but they still occur for 5/7 days per month on average.
Here is the average rainfall of the aforementioned Ponta Delgada, on the southeastern island of São Miguel.

The amount of sunshine on the Azores is not high, especially in the period from October to April, when the skies are often cloudy. Besides, sometimes there can be wind storms in the period from November to March.

Some of the islands are covered by hills or mountains. The highest peak is Mount Pico, on the island of the same name; it's a volcano of 2,351 meters (7,713 feet) and is also the highest mountain in Portugal. On the slopes of the mountain, there is not much sun and the rainfall is abundant, while the summit can be covered with snow in winter and spring.


Sea temperature

From July to September, the ocean at the Azores Islands' beaches is not warm to swim in, but overall it's acceptable, at least for those who are not sensitive to cold: the water temperature is 22 °C (72 °F) in July and 23 °C (73 °F) in August and September. Here are the average sea temperatures.

Best Time

The best time to visit the Azores is summer, from July to August, since it is the warmest and sunniest of the year. Having an oceanic climate, the Azores experience a delay in the sea warming, which affects the air temperature as well, so much so that September is slightly warmer than June, and temperature-wise it is still a summer month, even though the rains become a bit more frequent. In July and August, the temperatures are pleasant, the sun shines quite often and the rains are not so frequent, while June is a bit cooler and more cloudy.

What to pack

In winter: bring spring/autumn clothes, a sweater, a jacket, a raincoat.
In summer: bring light clothing, but also a sweatshirt or sweater, a light scarf for the wind, a light jacket, a raincoat or umbrella.
