Weather in Chefchaouen in September

A good month. September is a solid month to be in Chefchaouen. Highs average 30.9 °C, lows 17 °C, and rain falls on 6 days — nothing in the month is working against you.

September ranks 5 of 12 in Chefchaouen: past the worst of the year but short of May, which is the month to book if the dates are open.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 30.9 °C days and 17 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 5 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest September day reached 42.9 °C and the coldest night fell to 11.1 °C, and the wettest single day dropped 37 mm — roughly 116% of the month's rain in one day.

This is the volatile part. September rainfall has ranged from 2 mm to 96 mm across the twenty years measured — a 94 mm spread around an average of 32 mm. The average is real but almost no individual September looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 4.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 58%.

How September sits in the year

The month is on the way down: 5.9 °C cooler than August, with October dropping another 5.4 °C. The first week and the last are not the same trip. Rain has already shifted: 5 days more than August had.

Daylight in September

12.5 hours of daylight, losing 1.1 hours across the month. That is between Chefchaouen's extremes of 14.5 and 9.8 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 31.7 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Chefchaouen versus nearby

If Chefchaouen is one option among several, the nearby comparison is worth making. Tangier is a better bet in September — 5.9 °C cooler, 2 days less rain. Fes is the weaker option in September — 2.9 °C warmer, 1 day less rain.

So: September works, with May the better month by 16 points if the dates can move. If they cannot, nothing here should stop you booking.
