Weather in Agadir in September

A good month. September is a solid month to be in Agadir. Daytime highs average 34 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.

September ranks 9 of 12 in Agadir: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain falls on only 2 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: 11 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest September day reached 44 °C and the coldest night fell to 16.7 °C, and the wettest single day dropped 27 mm — roughly 300% of the month's rain in one day.

This is the volatile part. September rainfall has ranged from 1 mm to 39 mm across the twenty years measured — a 38 mm spread around an average of 9 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 7.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 51%.

How September sits in the year

The month is on the way down: 4.4 °C cooler than August, with October dropping another 3.1 °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 Agadir's extremes of 14.1 and 10.2 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 21.2 °C in September — comfortable for a proper swim. This is the warmest the water gets all year.

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 Agadir versus nearby

If Agadir is one option among several, the nearby comparison is worth making. Marrakesh is the weaker option in September — within a degree on temperature, 1 day more rain. Casablanca is a better bet in September — 4.9 °C cooler, 2 days more rain.

So: September is a compromise. January is 29 points better and is what Agadir is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
