When to go to Jordan? Seasons, desert heat and the crowds at Petra

Spring (March to May) and autumn (September to November) deliver everything you want from a Jordanian road trip: 20–28°C on the highlands, desert workable all day, mild nights in Bedouin camps, and the northern hills green and carpeted with red anemones in March–April. It's the period we recommend without reservation — and it's also the one everyone picks.

A study by Nayif Al-Zboun published in 2018 in Modern Applied Science, analysing eleven years of visitor numbers at Petra (2006–2017), confirms this double seasonality: the two annual visitor peaks fall in April, then October–November, bracketing seven months of low season (available on Google Scholar: scholar.google.com/scholar?q=Al-Zboun+Measuring+Seasonality+Tourism+Demand+Petra+Jordan). The practical consequence: in April and October, enter Petra at the 6 am opening — the Siq fills up from 9:30 am with groups coming off the Aqaba cruise ships.

The Jordanian summer is not uniform. On the heights of Amman, Madaba and Petra, days reach 30–34°C but the dry air and cool nights (18–20°C) keep travel entirely tolerable. The Jordan Valley, the Dead Sea (420 metres below sea level), Wadi Rum and Aqaba, however, regularly top 38–42°C: visiting them in summer means desert hours — outside from 6 to 10 am, siesta, back out after 4:30 pm.

A summer road trip therefore works by inverting the usual logic: sleep high (Petra, Dana, Ajloun), drop early in the morning to the low points, climb back before noon. Your rental car's air conditioning isn't a comfort feature but a safety item — test it at pick-up, along with the rest of our Jordan rental checklist.

The Jordanian winter surprises people: 8–14°C by day in Amman and Petra, frequent night frost on the highlands, and one to three snow events a year that can briefly block the King's Highway and close Petra for a day. Wadi Rum offers mild days (15–18°C) but nights near 0°C — Bedouin camps provide blankets and stoves, worth checking before booking.

Winter has two big cards to play, though: Aqaba and the Red Sea (water at 22–23°C, diving year-round) and near-deserted sites on weekdays. It's also flash flood season: after rain on the plateau, Petra's Siq and the wadis (Mujib, Bin Hammad) can close without notice. Never push into a wadi in the rain, even under a locally blue sky — the water comes from upstream, not from the sky above you.

Petra can be visited year-round but earns itself differently: in summer, a 6 am entry is mandatory and you should be back up the Siq before 11 am; in winter, superb light from 8 am and the site to yourself on weekdays — at the price of shorter days (closing at 4 pm in winter versus 6 pm in summer, check locally). The Monastery (Ad Deir) and its 850 steps can be climbed in any season, never between 11 am and 3 pm in summer.

Wadi Rum is at its peak in spring and autumn for overnight camps; the Dead Sea is swimmable year-round (the water rarely drops below 21°C) but becomes a furnace in summer. As for the north — Jerash, Ajloun, the desert castles — it follows Amman's climate: perfect October to May, hot but workable in summer.

Ramadan (whose dates move back about eleven days each year — check them for your travel year) doesn't close the country to visitors, but it changes its rhythm: city restaurants closed during the day outside tourist zones, occasionally reduced site hours, and very lively roads just before the breaking of the fast at sunset — the one time of day when it's better not to drive.

The major sites (Petra, Jerash, Wadi Rum) stay open and hotels serve non-fasting guests normally. The Eid holidays, on the other hand, fill hotels and sites with Jordanian and Gulf visitors: if your dates overlap, book accommodation and Rum camps well ahead.
