Dubai's heat is legendary — and it can genuinely be dangerous if you're not prepared. Summer temperatures regularly hit 45-50°C (113-122°F) with humidity that makes it feel even hotter. But even in the 'cool' season (November to March), midday sun can catch tourists off guard. This guide covers everything you need to know to stay safe, comfortable, and healthy in Dubai's heat.
Every year, hundreds of tourists suffer from heat exhaustion in Dubai. The combination of extreme temperatures, low humidity (or extreme humidity in summer), and the sheer amount of outdoor walking catches visitors off guard. The problem is amplified because Dubai looks modern and air-conditioned — tourists assume they'll always be comfortable. But the walk from a taxi to a mall entrance, a desert safari, or an outdoor souk visit can be brutal without preparation. Key fact: Dubai's "feels like" temperature in summer can reach 60°C (140°F) due to humidity. Even in winter, UV radiation is significantly higher than most European or North American cities.
November to February — Comfortable (20-28°C) The "cool season" and peak tourist time. Comfortable for outdoor activities but midday sun is still strong. You can walk outdoors for extended periods. March & April — Warming Up (25-35°C) Getting hot but manageable. Plan outdoor activities for morning or evening. Afternoons are uncomfortable for walking. May to September — Extreme Heat (38-50°C) Dangerously hot. Limit outdoor exposure to 15-20 minutes. Dubai essentially moves indoors during these months. Most outdoor attractions are deserted. October — Transition (30-38°C) Still hot but cooling down. Similar to March/April — stick to mornings and evenings for outdoor time. Pro tip: The UV index in Dubai reaches 11+ (extreme) even in winter. Sunburn can happen in 15 minutes of unprotected exposure.
