The northwest of the country has a Mediterranean climate with humid but mild winters and warm, dry summers. The average maximum in summer is usually over 30 degrees, in winter between 12 and 16 degrees. At the Red Sea it gets even warmer with average maxima between 35 and 40 degrees in summer. Even in the winter months, the maximum temperatures are usually above 20 degrees. In the south and east of Jordan a continental desert climate predominates. The temperature differences between day and night are very large. In summer, 40 degrees are often exceeded, in winter temperatures can be well below 20 degrees. Rainfall decreases from west to east and from north to south. In the mountains in the west 300 to 800 mm fall per year, while in the eastern desert areas only 50 to 100 mm go down. The rainy season lasts from November to March. Between June and September there is no rain at all in many regions of the country.
The most pleasant temperatures for travelling to Jordan are in April, May, October and November, although after the rainy season in April and May the country is much greener than after the summer months. The time between May and September is the best time for a bathing holiday on the Red Sea, but even in the winter months the temperatures are sufficient for bathing.
