Average temperature across Djibouti in May.
By May the midday sun is intense and the harbour feels hotter; mornings offer the most comfortable window for sightseeing or catching the ferry to Moucha or Maskali islands. Humidity begins to rise, making the city feel heavier; bring loose, breathable clothing and a refillable water bottle. Evening sea breezes sometimes provide relief, but plan outdoor excursions early and keep alternative indoor options in mind.
Moucha, Maskali
May brings warm, sometimes sultry conditions and a build in sea temperature; currents can change visibility, so dive operators may vary sites each day. The islands are less crowded than winter months, giving a quieter feel for beach camping and fishing trips; ensure you have plenty of water and shade for the midday heat. Ferry schedules remain fairly regular, but a flexible itinerary helps if rougher afternoons appear.
Day Forest
May’s highland warmth increases and daytime treks become more strenuous; mornings still afford the best hiking. Heat can build quickly, making ridge walks uncomfortable by mid-morning; plan to be off exposed sections before the strongest sun and watch for reduced shade near higher ridgelines. Nights are warm but noticeably cooler than the coast, offering some respite for campers.
May increases the intensity: the salt flat and surrounding lowlands bake under relentless sun, and reflected heat makes brief excursions draining. Expect minimal services; plan to arrive with a full tank, water and emergency supplies. Sunrise and sunset photography are the main activities that remain practical, while daytime crossing of the flat should be avoided by all but well-prepared convoys.

May moves the region toward sustained high temperatures, and by day the plains can feel stifling; early departures for hikes are essential. Fuel and water logistics become more important for overland travelers as services thin in remote areas; stock up before long drives. Expect quieter roads and fewer tourists, which makes independent exploration inviting for well-prepared visitors.
There are no major festivals or events in Djibouti during May to be aware of.
