Qatar has a dry, subtropical desert climate. The sun shines virtually every day and rainfall is almost non-existent, averaging about three inches (80mm) a year and falling only in winter. Summers (June to September) are sizzling hot by day, and warm at night, with temperatures often hitting 104°F (40°C) or above. Winters are only slightly cooler by day but can be very chilly at night. The best time to visit Qatar is between October and April, when daytime temperatures are bearable and there is little threat of sand storms.
