Gibraltar, where it is

The climate of Gibraltar, a small British territory in southern Spain, is Mediterranean, with mild, rainy winters and warm, sunny summers, but it has a peculiar microclimate, wet and windy, and it's protected from both the freezing cold and the intense heat because of its location on the strait of the same name, but also because of the presence of the Rock, a promontory overlooking the city, 426 meters (1,398 feet) high.
Here are the average temperatures.

Precipitation amounts to nearly 800 millimeters (31.5 inches) per year, and follows the Mediterranean pattern, so it's more abundant from November to March, when it's equal to or higher than 100 mm (4 in) per month (and during some years it can be abundant), while it is very rare in summer.

The wind blows frequently: in the cold half of the year it blows from the west, together with Atlantic depressions, while in spring and summer, in periods of good weather, the levant (easterly wind) blows, a moderate or strong wind that increases its speed when channeled into the strait. Sometimes the wind creates a peculiar cloud on the Rock of Gibraltar, which insists especially in the central part of the city, and can also partially come down towards the plain, generating some fogs.

Winter, from December to February, is mild, and characterized by sunny periods, alternating with periods of bad weather, with wind and rain. The rains during some years can be particularly heavy or frequent. On the other hand, for its southern location, and in a peninsula surrounded by the sea, the city is protected from the cold: the temperature rarely drops below 5 °C (41 °F) at night, and it rarely remains below 10 °C (50 °F) during the day.

Spring, from March to mid-June, is mild, and over the weeks receives gradually less rain and more sunshine. In March, and sometimes in the first half of April, there may still be heavy rains. In May and June, with the arrival of good weather, the cloud above the rock often forms, and the weather remains cool and moist.

Summer, from mid-June to mid-September, is warm and sunny, but less than in southern Spain. Typically, the temperatures are not very high, and remain below 30 °C (86 °F); the air is moist and sea breezes blow, sometimes lively. Even in July, and more rarely in August, there may be some quite cool and cloudy days, with highs around 25/27 °C (77/81 °F). Sometimes, however, the wind from Africa brings some particularly hot days, with highs about 35 °C (95 °F).

Autumn, from mid-September to November, is mild; rainy periods gradually increase. In September, there are still many warm and sunny days. By November, but sometimes also by October, we are now well into autumn, with a mild weather, but cloudy and rainy as well.

Given the infiltration of water from the Atlantic Ocean, the Alboran Sea near Gibraltar is not warm to swim in, and it is still very cool in June, when the water temperature is about 20 °C (68 °F), then it rises to 22 °C (72 °F) from July to September. Here are the average sea temperatures.

Best Time


If you want to go hiking, the best time in Gibraltar is late spring, from mid-April to mid-June. However, since in summer it's usually not too hot, you can also choose this season, bearing in mind that if you want to combine the trip with an excursion to Andalusia you will find an intense heat, especially in inland areas (therefore in this case you can choose April, May and October, as we recommended for Seville). Autumn is mild, but it can be very rainy, as well as winter.
The best time for a beach holiday is summer, from June to mid-September. It's better to bring a sweatshirt or sweater for cool and windy evenings, especially in June, but for safety also in July and August, especially if you are sensitive to cold.
Beware of monkeys, which reign supreme in the rock and steal bags from tourists.
