Jordan: A moderate air mass will lower temperatures to the twenties midweek.

Arab Weather - Weather forecasters at the Arab Weather Center indicated that the latest advanced computer outputs indicate that the Kingdom will be affected, God willing, in the middle of the week by a moderate air mass, and thus temperatures will drop to be around or slightly lower than their average for this time of year. The weather will be moderate over the mountainous heights, tending to be hot in the low-lying areas, and hot in the Jordan Valley, the Dead Sea and Aqaba, with the appearance of low clouds, and maximum temperatures will be between 24 and 27 degrees Celsius over the main cities.

The Kingdom will begin to be affected by a moderate air mass on Tuesday.

The Kingdom will begin to be affected on Tuesday by a moderate air mass, with temperatures dropping to around their usual rates. The weather will be cool in the morning as school students head back to school, and will be semi-autumnal and moderate in most parts of the Kingdom for the rest of the day (continuing to be hot in the Jordan Valley, the Dead Sea and Aqaba). Low clouds will appear, especially in the north and center of the Kingdom, especially in the early morning hours. Winds will be moderate northwesterly, gradually turning active and accompanied by strong gusts exceeding 50 km/h, causing dust storms in the south and east of the Kingdom.

On Wednesday, September 17, 2025, temperatures will remain around average or slightly lower, with semi-autumnal weather prevailing, tending to be cool in the early morning hours, and pleasant to moderate temperatures in various regions for the rest of the day, despite the fact that we are still in the summer season, astronomically speaking. Moderate northwesterly winds will continue, picking up in the afternoon.

High temperatures drop to the mid-twenties Celsius over the mountains.

Maximum temperatures on Sunday and Monday will be in the mid-twenties Celsius to slightly higher over the high mountainous areas, including the highlands west of the capital, Amman, while they will reach the late twenties in the rest of the lowlands, and touch the late thirties in the Jordan Valley, the Dead Sea, and Aqaba.

A significant drop in minimum temperatures and a colder weather

The latest numerical model outputs indicate that minimum temperatures will drop to between 14 and 17 degrees Celsius over the high mountain peaks and eastern plains, while minimum temperatures will be less than 14 degrees Celsius over the peaks of the Sharah Mountains, amid a relatively cool to cold but refreshing atmosphere.

Humid air currents from the Mediterranean are expected to sweep in during these nights, with humidity levels rising to over 90% in some parts of the Kingdom. The weather will be remarkably humid with low clouds and the possibility of fog forming over some mountainous areas and some areas of the eastern plains.

Weather forecast in Jordan, Amman

The weather then (i.e., after midnight and early morning) becomes unsuitable for outdoor gatherings due to the combination of cool conditions and high relative humidity, as well as occasional active northwesterly winds. Therefore, "Arabia Weather" advises school students to wear a light coat to accommodate the relatively cool weather during the dawn and early morning hours.

And God knows best.
