Meteo Chefchaouen (Blue City) in marzo

Morocco-forum threads on March weather single out the spring window (March through May) as the recommended stretch for Fes specifically, warm days and cool nights suited to walking the medina without the summer heat. Posters are candid that it's variable within that window - it can rain a bit, but it can also turn lovely and sunny with daytime temperatures around 20C, cold enough after dark that a fleece and long sleeves are the standing packing advice. One regional note worth knowing: the weather generally runs better in Marrakech and further south than it does in Fes at the same time of year, so don't assume Fes matches what you've read about the rest of the country. The record: 20.9C days feeling like 19C, 7.6C nights, 81mm of rain across 11.5 days and 9.8 hours of sun - genuinely changeable, cool nights guaranteed either way.

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.
