Casablanca in December

December returns Casablanca to its mild, wet Atlantic winter. Daytime highs around 18°C are never cold by Moroccan standards, but the rain picks up in blustery ocean fronts and evenings turn cool and damp. The city stays quiet and good value outside any festive-week uptick, and the Hassan II Mosque, the Art Deco centre and the Habous quarter can all be enjoyed in calm, with few other visitors about.

This is a month for the indoor, cultural Casablanca, with outdoor time slotted into the bright breaks. The mosque's guided interior, the Villa des Arts, the central market and a long café morning all suit a grey afternoon, while a clear spell is the moment for a brisk Corniche walk in the sharp winter sea light. Showers tend to come and go rather than settle in, so dry windows reliably appear if you stay flexible.

For travellers framing Casablanca as a business-and-culture stop or a gateway to the imperial cities, December works well and cheaply, with Rabat an easy hour up the coast. Pack a proper waterproof and keep the plan loose around the weather, and the month offers a calm, mild and inexpensive city stay — Morocco's most temperate big-city winter, even at its wettest.
