Climate report: Excellent performance of the rainy season so far and dams in a reassuring water situation

Arab Weather - The Arab Weather Regional Center issued an extensive evaluation study on the performance of the rainy season up to 4-2-2026, following the end of the winter forty days and the beginning of the winter fifty days in the Kingdom. In this study, we will put in your hands a comprehensive and complete evaluation of the performance of the rainy season, which can be said to have been excellent up to the moment in the agricultural areas of the north and center of the Kingdom, and even in the agricultural areas and dams in the south.

First: A general description of the behavior of the rainy season so far and the nature of the weather patterns that affected the Kingdom during the winter season of 2025-2026

In a related context, the Kingdom was affected by a considerable number of weather depressions, reaching about 11 weather depressions up to 4-2-2026. Some of them had complete scientific characteristics and were classified as very advanced, such as the fourth degree, while most of them ranged within the framework of the second degree, and some of them carried the third degree. These depressions were characterized by the speed of their impact but at the same time by the abundance of rainfall, as the weather depressions were characterized by the rainfall of large amounts of rain, although the duration of the impact of these depressions was mostly no more than 30 hours.

Second: Evaluating the reality and performance of the rainy season up to the beginning of the fifty-day winter period of 2026

To assess the reality and performance of the 2025/2026 rainy season up to the beginning of the fifty-day period (knowing that the climatic rainy season in Jordan begins at the beginning of October and ends in the middle of May, including three months of winter, namely December, January and February), we must look at several aspects, which are:

Number of weather depressions that affected the Kingdom up to the date of this report

The Arab Weather Center compiled data related to the number of weather depressions that affected the Kingdom since the beginning of the rainy season until the date of preparing this report, and it was found that Jordan was affected by a fourth-degree (highly effective) weather depression, while it was affected by “5” second-degree (normal winter) weather depressions and 5 third-degree weather depressions (which include weather depressions ranging in intensity from moderate to highly effective), and naturally, since the issuance of the classification, we have not been exposed to any fifth-degree weather depression because this degree only includes exceptional storms, for example, the Alexa storm classification.

Rainfall performance in the governorates compared to what is expected up to 4/2/2026:

The forecasters at the Arab Weather Center, after comparing the actual amount of rainfall achieved this rainy season with what is expected to fall, which is calculated based on the average rainfall over the past thirty years, found that the performance of the rainy season so far is as follows:

Exceeding the assumed totals:
Southern Ghor 213%, Zarqa 186%, Karak 174%, East Amman 136%, West Amman 135%, Salt 130%, Central Ghor 130%, Mafraq 127%, Ma'an 124%, Irbid City 122%, Ajloun 122%, Tafilah 119%, Madaba 105%, Aqaba 104%

Regarding the assumed totals (from 70–100):
Wadi Al-Rayan and Al-Baqoura in the northern Jordan Valley 98%, Jerash 96%, Azraq South 91%, Al-Safawri 87%, Al-Shoubak 82%

Much lower than the assumed totals:
Wadi Musa only receives 37% of the rainy season.

The water situation is very reassuring in the Kingdom's dams.

The Kingdom's main dams have recorded excellent storage levels so far, according to the Ministry of Water and Irrigation. Several dams have reached full capacity: Wadi Shuaib Dam in Balqa Governorate, with a storage capacity of approximately 1.5 million cubic meters; Mujib Dam in Madaba Governorate, with the highest storage capacity among all dams, reaching 25 million cubic meters; and Zarqa Ma'in Dam in Madaba Governorate, with a capacity of approximately 2 million cubic meters. In Karak Governorate, Al-Lajoun Dam has reached a storage capacity of 1 million cubic meters, Wadi Karak Dam 2 million cubic meters, and Bin Hammad Dam 4 million cubic meters. In Tafila Governorate, Shitam Dam has reached a storage capacity of 750,000 cubic meters.

Water Ministry spokesman Omar Salameh explained that this season's rainfall has contributed to the accumulation of approximately 150 million cubic meters of water in dams, with an overall filling rate ranging between 75% and 80% of their storage capacity. For his part, Minister of Water and Irrigation Raed Abu Saud confirmed that the King Talal Dam has reached about 95% of its capacity, emphasizing the need to continue preparations and measures to address any new rainfall that may occur in the coming period.

Note: The amount of rainfall achieved in relation to the total annual rainfall average, and the rainfall performance of the Kingdom’s governorates, are from the reports issued by the Meteorology Department.

Praise be to God for every drop of rain .
