Casablanca’s Atlantic-facing position gives it a different seasonal rhythm from Morocco’s inland cities. Summer here is warm rather than scorching (Marrakech hits 37°C in July while Casablanca stays at 26°C), and the coastal fog known as the marin can blanket mornings from June through August. Here’s the best time to visit Casablanca for different priorities with specific date ranges.
Best Time to Visit Casablanca for Good Weather: May and September to October
May and the September 15 to October 31 window deliver the best combination of warmth, low rain and manageable humidity. May temperatures reach 22°C (72°F) with just 12mm of rain and 10 hours of daily sunshine before the summer fog arrives. September and October average 24-26°C (75-79°F) with the Atlantic at 22°C (72°F), warm enough for swimming. These months have less than 27mm of rain and the marin fog has largely receded. These are the best periods for walking the Art Deco streets of the city centre and photographing the Hassan II Mosque without sweating through your clothes.
Best Time to Visit Casablanca for Low Prices: November to March (Except Holidays)
Hotel rates in Casablanca drop 30-50% from November through March outside the December 20 to January 5 holiday period. Business hotels that charge 1,200-2,000 MAD (€110-180) in summer can be booked for 600-900 MAD (€55-82). The trade-off is weather: expect rain on roughly one day in three (60-70mm monthly), temperatures of 8-20°C (46-68°F), and 5-6 hours of daily sunshine. The Casablanca weather by month guide has full climate data. For business travellers on a budget, this period offers the best value.
Best Time to Visit Casablanca for Fewer Crowds: February and November
February and November are Casablanca’s quietest tourist months. In February you’ll find the Hassan II Mosque tours half-full rather than sold out. November sees empty tables at the Corniche seafood restaurants and no queues at the Morocco Mall. Both months have moderate weather: February averages 18°C (64°F) with 50mm rain, November 20°C (68°F) with 60mm. You’ll encounter some rainy days but far fewer people.
Best Time to Visit Casablanca for Events: April and July
The Casablanca Jazz Festival (Jazzablanca) runs in late April with international and Moroccan acts across multiple city venues. The Casablanca Festival in July brings free concerts, street theatre and art installations to public spaces. The International Book Fair (SIEL) in February draws Arabic, French and English publishers to the city’s exhibition centre.
Months to Avoid in Casablanca and Why
June and July suffer from persistent morning coastal fog (the marin) that can blanket the Corniche until 10:00-11:00, reducing usable beach and sightseeing hours despite high humidity of 79-80%. December has the most rain (70mm over 10 days) and the shortest days (5 hours of sun). If you want guaranteed sunshine without the marin, choose May or September-October over summer months. Casablanca’s summer is never unbearably hot (max 27°C), so the main weather issue is grey mornings rather than heatstroke, unlike inland Marrakech.
