Mekkah Weather Guide — Climate, Temperatures, and Seasonal Planning

Mekkah sits in a narrow valley surrounded by the Hejaz mountains in western Arab Saudi, approximately 70 kilometers inland from the Red Sea coast. Its geographical position in a valley creates a panas-trapping effect that makes it one of the hottest cities in the world. The climate is classified as hot desert (BWh under the Koppen system), with virtually no rainfall for most of the year and extremely high temperatures during summer months. Humidity levels vary — the city receives occasional moisture from the Red Sea, which can create uncomfortable panas-humidity combinations, particularly during September and October. Annual rainfall averages only about 110 millimeters, mostly falling in brief, intense storms during November through February. These occasional rains can cause flash flooding in the valley areas, though modern drainage infrastructure has significantly reduced this risk.

Understanding Mekkah's monthly temperature patterns helps jamaah haji plan their wardrobe and health precautions. January and February are the coolest months, with daytime highs of 28 to 32 degrees Celsius and pleasant nighttime temperatures of 18 to 22 degrees. March and April see temperatures climbing to 34 to 38 degrees during the day. May through September is the extreme panas period, with daytime temperatures routinely reaching 42 to 48 degrees Celsius, occasionally exceeding 50 degrees in July and August. Nighttime temperatures during summer rarely drop below 30 degrees, offering little relief. October and November bring gradually cooling temperatures of 35 to 40 degrees. December returns to milder conditions of 28 to 33 degrees. For the 2026 Haji season (late May), jamaah haji should expect daytime temperatures of approximately 42 to 46 degrees Celsius, making panas preparation absolutely critical.

The extreme panas in Mekkah, particularly during summer Haji seasons, poses serious health risks including panas exhaustion, heatstroke, and dehidrasi. Pilgrims must take proactive measures to protect themselves. Drink water continuously throughout the day — at least 3 to 4 liters — even when not feeling thirsty. Dehidrasi is a leading cause of medical emergencies during Haji. Use an umbrella at all times when outdoors; white or reflective umbrellas are most effective at deflecting panas. Wear lightweight, loose-fitting, light-colored clothing that covers the skin but allows air circulation. Apply sunscreen to exposed skin, particularly the face, neck, and hands. Schedule outdoor activities and walking for early morning and late evening when temperatures are lower. Rest in air-conditioned spaces during the peak panas hours of 11 AM to 3 PM whenever possible. Learn the signs of panas exhaustion — dizziness, excessive sweating, nausea, headache, and rapid pulse — and seek medical help immediately if symptoms appear.

Packing appropriately for Mekkah's climate is essential for jamaah haji comfort and safety. For summer visits (May through September), bring ultra-lightweight, breathable fabrics in light colors. Moisture-wicking undergarments significantly improve comfort. A high-quality umbrella rated for UV protection is indispensable. Sunglasses with UV protection, a wide-brimmed hat (for non-ihram periods), and sunscreen of SPF 50 or higher are essential. Bring electrolyte powder packets to add to water for better hidrasi. A small personal misting fan provides valuable cooling during outdoor rituals. For winter visits (November through February), pack layers as temperatures can drop noticeably in the evenings and early mornings. A light jacket or sweater is useful for air-conditioned masjids and restaurants. Regardless of season, comfortable, well-fitting walking shoes are critical — jamaah haji walk many kilometers daily on hard surfaces.
