Været i Chefchaouen (Blue City) i september

September here is barely cooler than August by the board's account - still hot, still a high sun index - and our row gives 26.1C reading as 27C over 20.1C nights with 17.4mm of rain across 2.9 days. The detail worth having is geographical: the sun does not clear the Rock until about half past ten, so the town sits in cool shade for the first hours of the day, which is when to walk it. The beaches are on the eastern side and the sea is 21.8C, warm enough that the changing rooms stay open to the end of the month. A 20.2 kph wind keeps 74 percent humidity from feeling heavy. The record: 11 hours of sun and AQI 56.

Forum posters describe November in Chefchaouen as cooler and very possibly rainy, with more recent accounts specifically warning it can turn cold, rainy and genuinely miserable by late in the month. Posters attribute this partly to the town's setting - not just in Morocco's colder north but also at roughly 700-750m elevation, surrounded by mountains whose weather runs even less predictable than the surrounding lowlands. Posters consistently recommend layered clothing with a wind- and waterproof shell as essential for a November visit. Posters generally rate November as a weaker pick for Chefchaouen weather-wise, with spring (April-May) or September consistently recommended instead as better alternatives.

May is the forum's month for northern Morocco — longer days, greenery, spring flowers, and unlikely to be either too hot or too cold. Chefchaouen adds its own variable: at 750m the mountain weather changes fast, and posters describe all four seasons thrown at you in a single day. The record puts May at 24°C by day and 14 overnight, warmer than the 19–21°C some visitors report, while one 2025 trip report describes an early heatwave running hot and dry. Spring rains more here than December does, though at under six wet days it is hardly a washout. Layers — and May rather than late March.
