Casablanca weather season by season
Winter (December to February): mild and the wettest season
Winter brings most of Casablanca’s rain, usually in passing Atlantic fronts rather than long grey spells, with sunny days in between. Daytime temperatures of 17-18°C are comfortable for sightseeing, but the damp sea air makes evenings feel cooler than the numbers suggest. Pack a waterproof jacket and a warm layer.
Spring (March to May): fresh and pleasant
Rain becomes less frequent, the countryside is green and temperatures climb to around 20-22°C. Spring is an excellent time to combine Casablanca with Rabat, Fes and Chefchaouen, and with the Sahara, which is warm but not yet hot.
Summer (June to August): warm, humid and dry
Casablanca stays far cooler than inland Morocco in summer, thanks to the ocean. Highs are around 24-27°C, rain is rare, and mornings often start with sea mist that burns off by midday. Humidity is high, and the beaches of Ain Diab fill up with Moroccan families on summer weekends. If you travel to Marrakech or the desert in July or August, expect much hotter conditions there.
Autumn (September to November): warm sea, golden light
September and October are some of the nicest months in Casablanca: warm days, the warmest sea of the year and fewer crowds than summer. The first autumn rains usually arrive in late October or November.
Winter (December to February): mild days, most of the rain
Winter is when Casablanca weather is at its most changeable. Days are usually around 17-18°C, often bright between Atlantic fronts, while nights drop to about 8-9°C and the sea air makes evenings feel cooler. Most of the year’s rain falls between November and March, so pack a light waterproof and a warm layer. It is a comfortable season for sightseeing in the city, and a good time to combine Casablanca with Marrakech and the imperial cities, though desert nights further south are cold.
When is the best time to visit Casablanca?
- Best overall: April to June and September to October, for sunny, comfortable days and little rain.
- Best for the beach: July to September, when the sea is warmest.
- Best for a full Morocco tour from Casablanca: March to May and late September to November, when Marrakech and the Sahara are also pleasant.

Also consider Ramadan, whose dates move about 11 days earlier each year. Daily life slows during the day and evenings become lively after sunset; read our guide to Ramadan in Morocco for tourists.
