Weather and climate in Casablanca (Morocco)

In Casablanca, a city located on the Atlantic coast of Morocco, the climate is very mild, similar to that of the coast of Southern California: in fact, along the coast of the Atlantic Ocean, a cold current flows, which can cause some morning fogs and is able temper the summer heat. The climate in itself would be great, but unfortunately, the city is polluted; pollution is favored by the stability of the weather, especially in spring and summer.
The average temperature ranges from 13 °C (55.5 °F) in January to 24 °C (75 °F) in August. Here are the average temperatures.

Rainfall is not abundant, in fact, it amounts to 425 millimeters (16.5 inches) per year, and follows the Mediterranean pattern: it is concentrated from October to April, while in summer, it almost never rains. Here is the average precipitation.

Winter, from December to February, is mild: the average temperature in January is about 13 °C (55.5 °F). There are many sunny periods, alternating with periods of bad weather due to Atlantic depressions, which pass more frequently over this area than in southern Morocco (ie in cities like Agadir). Sometimes, it can get cold at night, in fact, the minimum temperature can approach freezing (0 °C or 32 °F). On other occasions, the wind from the desert can bring some hot days, with maximum temperatures about 28/30 °C (82/86 °F).

Spring, from March to mid-June, is mild or pleasantly warm, and often sunny. In March, Atlantic disturbances still pass quite frequently, but later, they become more rare. Some rainy days may occur still in April, and sometimes in May. Every now and then, there can be quite heavy downpours. In the first half of June, there are often morning fogs and mists that keep the temperature low, so there is still spring-like weather. Sometimes, however, the wind from the desert can raise the temperature to 30/32 °C (86/90 °F).

Summer, from mid-June to September, is warm. The weather is fine and it practically never rains, but in the morning, fogs and mists can form (though less frequently than in Agadir). Waves of hot weather are much rarer than on the southern Moroccan coast, and are also less intense, however, when they occur, the maximum temperature can reach 38/40 °C (100/104 °F).

Autumn, in October and November, is pleasantly warm and sunny at first, then it gradually becomes cooler. In addition, in autumn, the first rains occur, with the return of Atlantic weather fronts.



The amount of sunshine in Casablanca is good from April to September or mid-October, when good weather prevails, although a few hours of sunshine may be lost because of morning mists, while from November to March, when the sun still often shines, periods of bad weather with cloudy skies can occur. Here are the average sunshine hours per day.

The sea, quite cold in winter, remains a bit cool in the summer months, in fact, it reaches 21 °C (70 °F) in June, 22 °C (72 °F) in July and October, and 23/23.5 °C (73/74 °F) in August and September, when all in all, it becomes acceptable for swimming. Here are the average sea temperatures.
