Mamoudzou Weather in July

July: dry-season days

July feels warm and fairly dry in Mamoudzou, with highs around 26°C and lows around 25°C. Rain usually comes on only a few days, so you can explore the waterfront and Mamoudzou market without planning around frequent showers. The sea and ferry also make a trip across to Petite-Terre an easy fit.

For longer walks, drier conditions suit the climb up Mount Choungui, though the exposed trail can still feel hot. Skip ambitious walks if you don't do well in heat, and don't count on rain to cool you down.

Bastille Day and school holidays

France's national holiday, 14 July, is marked in Mayotte too. Mamoudzou may have local celebrations, and some shops or services can close, so check locally before relying on them. July also falls in the French school summer break, which can bring more holidaymakers and higher travel or accommodation costs than quieter months such as June or September.

If you hate crowds, aim for weekdays around the Mamoudzou market rather than the busiest holiday periods.

Getting around

July is part of Mayotte's drier season, which runs from May to October. It's a good time to pair town visits with time by the water, while the lower rain makes muddy trails less of a concern. August is drier still, but July is already a comfortable month for getting out.

A useful local tip: use the Mamoudzou–Dzaoudzi ferry to reach Petite-Terre, then visit the volcanic crater at Lac Dziani. The ferry is part of daily life here, not just a sightseeing ride; allow for queues around busy holiday times, and check the crossing schedule before building your day around it.
