Jordan Weather, climate and geography
Jordan is a year-round destination. Even in high summer (June-August), Amman and most areas around the country are not excessively hot, chiefly due to the moderating influence of altitude – Amman stands around 850m (2800ft) above sea level. Similarly, Petra enjoys an elevated position – around 1,100m (3600ft) above sea level, so here, too, although days in summer can be hot, nights are often rather chilly. For Petra, as well as decent walking shoes – the only way in and out of the ruins is by a moderately testing walk over stony ground – also bring something warm for the evenings, even in summer. In winter, Petra can be very cold, with rain and even snow.
The Jordan Valley and the Red Sea coast around Aqaba is warm during winter (December-February) – a pleasant relief from the chill elsewhere – but extremely hot in summer (June-August). In the Eastern Desert, the winter can be bitterly cold and dry and the summer intensely hot. Some high-altitude areas, such as Ajloun, Dana and Petra, can receive snowfall in winter. Rain falls in many areas across the country on higher ground between October and March.
