The climate in Jordan varies throughout the year according to seasons. Spring and autumn are generally the best times to travel, when the sun is warm and skies are clear. You can expect mild to hot temperatures and little or no rain during this time. Summers are very hot and dry, with temperatures ranging in the 90ºs-110ºs F. Winter is cold and rainy, and it is not unusual to see snowfall in the highlands, including Amman, during December and January. Hiking trails are sometimes closed after heavy rainfall.
