Average temperature across Bahrain in May.
Manama, Juffair, Seef
May pushes temperatures into the 30s and the humidity becomes obvious along the waterfront, making midday walks sweaty and slow. The Bahrain International Circuit’s pre-season activity and local festivals can bring crowds despite the heat; aim for early morning or late evening outings. Sea swims are possible but the gulf water is already warm, so snorkellers will find visibility reduced by thermal layers and occasional algae.
Muharraq City, Bahrain International Airport, Amwaj
May makes humidity obvious along the eastern coast, with daytime readings commonly in the low 30s and muggy evenings around the marinas. Recreational boating continues but with choppier conditions in the afternoons; operators often schedule trips for early morning. Ferry connections to small islands begin to feel less comfortable for prolonged exposure - bring water and avoid mid-afternoon sunburn.
Riffa, Isa Town, Sakhir, Royal Golf Areas
May turns very hot by late month with interior highs often in the mid-30s; humidity is less oppressive than on the coast but air is dry and dusty. Sakhir race activities and private events heat up the area, and many residents retreat to air-conditioned compounds during the afternoon. Travelers should avoid long mid-day drives, carry sun protection, and confirm bookings for any desert experiences.
Sitra, Hawar Islands, Southern Reefs
May turns noticeably hotter and more humid on the southern shores, with afternoons in the low 30s; the Hawar Islands’ sparse shade makes midday landings tiring without sun protection. Marine tours prefer early departures; late-afternoon light is stunning but also very warm. If staying on islands, ensure accommodations have good ventilation and reliable cold water supply, as evenings remain warm.
There are no major festivals or events in Bahrain during May to be aware of.
