Været i Jerash i mars

Regulars explain this month with a depth rather than a latitude: more than four hundred metres below sea level, which keeps it warm when the highlands are not, and thick enough air that they quote roughly a fifth more oxygen than at the coast. So March here is where people come down to escape the cold in Amman, and the end of March into early April is the peak. They warn the month is unpredictable - it can be warm and sunny, cloudy, or briefly torrential - and put the end of it in the low twenties, which is our 22.6C over 16.5C. The water runs 22 to 30C across the year with March at the cool end. The record: 27.1mm across 6 days, 10.4 hours of sun and AQI 60.

Jordan's forum consistently rates October as one of the best months for visiting sites like Jerash: warm, balmy days without the punishing heat of summer, cool breezy evenings that call for just a light fleece, and rain that essentially doesn't start until November. Multiple posters recommended layers specifically because the desert-adjacent evening breeze can catch you off guard even after a genuinely hot day. Since Jerash's ruins offer almost no shade, the milder October sun makes a real difference for a full day of walking the site.

Forum posters call April genuinely excellent for Jordan generally - spring weather with wildflowers covering the hills, not hot and not cold - though they note this is also peak season, meaning higher prices and busier sites, especially around Easter. One real caveat worth knowing: recent years have brought notably wetter March/early-April stretches, with rain tapering off more reliably toward the end of the month, so exact timing within April can matter. For Jerash specifically, posters recommend budgeting at least two hours to properly see the ruins, noting the site technically closes at 4pm but allows visitors already inside to stay until sunset - it's commonly paired with Petra, Wadi Rum, the Dead Sea and other sites on a week-long Jordan itinerary.
