Weather in Marrakesh in September
Morocco · 20-year averages, September
A hard month. September asks something of you. Go in knowing what. Daytime highs average 35.2 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.
September ranks 10 of 12 — near the bottom of Marrakesh's year. January is the month that works, and the swing between the two is 61 points, which is a different holiday rather than a slightly better one.
Rain falls on only 3 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.
What the averages hide
Averages flatten a month, and this one hides a few things: 16 days clear 35 °C, so a serious heatwave is normal rather than notable; the day swings 15 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest September day reached 43.7 °C and the coldest night fell to 13.7 °C.
This is the volatile part. September rainfall has ranged from 2 mm to 45 mm across the twenty years measured — a 43 mm spread around an average of 14 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 8.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 44%.
How September sits in the year
The month is on the way down: 5.3 °C cooler than August, with October dropping another 4.6 °C. The first week and the last are not the same trip.
Daylight in September
12.4 hours of daylight, losing 0.9 hours across the month. That is between Marrakesh's extremes of 14.2 and 10.1 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 33.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within September itself the daily swing is 15 °C, so mornings and afternoons need different clothes.
How busy it gets
Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
September in Marrakesh versus nearby
If Marrakesh is one option among several, the nearby comparison is worth making. Agadir is a better bet in September — within a degree on temperature, 1 day less rain. Casablanca is a better bet in September — 6.1 °C cooler, 1 day more rain.
So: September is a compromise. January is 43 points better and is what Marrakesh is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
