Marrakech: hotter days, cooler evenings

Marrakech is the hotter choice, with average daytime temperatures of 31°C. Days above 25°C account for 94% of September days here, so pack for heat rather than relying on mild weather. Put longer walks in the morning or later afternoon, and leave room for shade and a slower pace around midday. The catch is the contrast after dark: nights average 16°C, making a light jumper or overshirt useful when sitting outside. This suits travellers who want hot days without equally warm nights. If you find heat tiring, though, September in Marrakech still calls for care rather than a full day of walking in the sun.

Agadir: slightly cooler days and warmer nights

Choose Agadir if time by the sea matters more than having the hottest weather. Daytime temperatures average 29°C, so it remains hot rather than mild, and shade is still useful around midday. Nights average 20°C, giving you warmer conditions after dark than Marrakech. The sea also averages 20°C: comfortable enough for some swimmers, but potentially cool if you prefer warm water or tend to stay in for a long time. Agadir is the better fit for travellers who want hot days beside the water and less of a temperature drop in the evening. Pack light clothing, swimwear and sun protection, without assuming the sea will feel as warm as the air.
