With no vegetation to dampen its climate, it can be very hot in the summer and very cold in winter. Some winter nights there can be brutally cold. One thing you will notice in Jordan is that there is very little humidity, which hovers around 30-40% on average.

Yes, it gets surprisingly cold at night in Jordan, regardless of the season. Because much of the country is high-altitude desert, temperatures can plummet as soon as the sun sets due to the low humidity and lack of cloud cover. In the winter (December to February), nighttime temperatures in Amman or Petra can drop to 2°C to 5°C (36°F - 41°F), and snow is not uncommon. Even in the peak of summer (July and August), when daytime heat can exceed 35°C, the desert nights in Wadi Rum often drop to a crisp 15°C (59°F), requiring a jacket or fleece. In 2026, travelers are advised to pack for "four seasons in one day." A grounded peer tip: if you are staying in a traditional Bedouin camp, the tents are often unheated, so "layering" is a supportive necessity for a comfortable night's sleep under the stars. Never underestimate the desert's ability to transition from "scorching" to "shivering" in a matter of hours; always carry a versatile pashmina or light down jacket for those cool evening excursions.
