Casablanca-Settat in September

March through May gives you perfect weather — warm days around 22°C, cool evenings, and minimal rain. The Atlantic keeps temperatures moderate year-round, but summer gets humid and crowded with Moroccan families escaping inland heat. October and November offer the region's sweet spot: warm ocean temperatures, fewer crowds, and clear skies perfect for exploring. December through February brings rain and cooler temperatures, but hotel prices drop 40% and you'll have beaches mostly to yourself. Look, avoid July and August unless you enjoy sweltering humidity and packed beaches. The Hassan II Mosque gets unbearably crowded during Moroccan school holidays in July. Spring brings the added bonus of wildflowers along the coastal roads between Casablanca and Mohammedia.
