مكة has an arid desert climate with extremely hot summers and mild winters. Summer temperatures (June-September) regularly exceed 45 degrees Celsius (113 Fahrenheit). Winter months (December-February) are milder at 20-30 degrees Celsius. The الحج date rotates through the Islamic calendar, meaning الحجاج may face any season. Heat preparation is essential for summer الحج seasons.
مكة sits in a narrow valley surrounded by the Hejaz mountains in western المملكة العربية السعودية, approximately 70 kilometers inland from the Red Sea coast. Its geographical position in a valley creates a الحرارة-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 الحرارة-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 مكة's monthly temperature patterns helps الحجاج 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 الحرارة 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 الحج season (late May), الحجاج should expect daytime temperatures of approximately 42 to 46 degrees Celsius, making الحرارة preparation absolutely critical.
The extreme الحرارة in مكة, particularly during summer الحج seasons, poses serious health risks including الحرارة exhaustion, heatstroke, and deالترطيب. 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. Deالترطيب is a leading cause of medical emergencies during الحج. Use an umbrella at all times when outdoors; white or reflective umbrellas are most effective at deflecting الحرارة. Wear lightweight, loose-fitting, light-colored clothing that covers the skin but allows air circulation. Apply واقي الشمس 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 الحرارة hours of 11 AM to 3 PM whenever possible. Learn the signs of الحرارة exhaustion — dizziness, excessive sweating, nausea, headache, and rapid pulse — and seek medical help immediately if symptoms appear.
Packing appropriately for مكة's climate is essential for الحاج 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-الإحرام periods), and واقي الشمس of SPF 50 or higher are essential. Bring electrolyte powder packets to add to water for better الترطيب. 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 مسجدs and restaurants. Regardless of season, comfortable, well-fitting walking shoes are critical — الحجاج walk many kilometers daily on hard surfaces.
