Amman sits at 800 metres elevation in the limestone highlands, which means it is cooler and less humid than most other Middle Eastern capitals. The best times to visit are spring (March to May) and autumn (September to November), when temperatures are comfortable — typically 15–22°C — and rainfall is possible but not disruptive.
Summer (June to September) is warm and dry, with daytime temperatures reaching 30–35°C, but the elevation keeps it bearable, especially in the evenings. This is also the high season for tourism in Jordan, when Petra and Wadi Rum get very crowded. Winter (December to February) brings cold nights, occasional frost, and rare snow — Amman's hills turn white once or twice most winters, which surprises visitors expecting desert heat. Rain falls mainly between November and March.
Ramadan brings some disruption to daytime eating and shopping but also an atmospheric transformation — the downtown fills for iftar (breaking the fast) at sunset, and the night markets extend late. Non-Muslims are expected to avoid eating and drinking in public during daylight hours.
