Jordan has an extraordinary range of climates for such a small country. This is massively affected by the country’s diverse levels of altitude. You have the higher northern and central regions, which between December and February can be pretty cold, while at the same time, lower areas such as the Gulf of Aqaba and the Jordan Valley are boasting a pleasant average of 23°C. In summer, these lower regions become humid and very hot and are best evaded between July and August.
Still, no matter how hot it gets, it’s still more tolerable compared to its neighboring GCC Gulf countries. Amman and the highlands are practically always cool with fresh nights, where humidity is rare.
Your safest bet is to travel during spring and autumn (March-May and September–November). The temperatures aren’t too intense, and the wildflowers are in blossom all over the country, covering Jordan in an array of colors.
any time of year.
