Winter, from December to February, is mild: the average temperature in January is about 13 °C (55.5 °F).

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).

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).

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.
