July and August are the hottest and driest months of the year, especially in Amman and the Jordan Valley, and in the desert areas, with temperatures over 97°F (36°C). Spring and autumn are the most pleasant times to visit with clear, sunny days and moderate temperatures. The winter months from December to March can be very cold, particularly in Amman, with snow, rain and wind, but there is little rainfall in the desert regions and in Aqaba, which makes a pleasant wintertime resort. About 75 percent of the country can be described as having a desert climate with very little annual rainfall.
