MUSCAT: Monday’s rainfall in Muscat at 96mm was more than the governorate’s annual average.

Historical data available with Directorate General of Meteorology and Air Navigation (DGMAN) says that Muscat averages 75mm of rainfall annually, while for the month of December, the average is 16.5mm.

The entire sultanate receives an average rainfall of 117mm a year. According to the Ministry of Regional Municipalities and Water Resources’ rainfall monitoring centres, Monday’s rain resulted in heavy flooding and overflowing of several wadis.

The wilayats of Muttrah and Hamriya received 96mm and 90mm rainfall, while Amerat, Bausher and Seeb recorded 53mm, 47mm and 41mm rainfall respectively.

The other areas that received high rainfall were Bukha in Musandam (47mm), Buraimi (36mm), Khasab (32mm), Nakhl in South Batinah (31mm) and Bidbid in Dakhliyah (26mm).

An analysis of a 27-year data in Oman shows that the highest rainfall is recorded in February and March and accounts for 35.9 per cent of the yearly rainfall.

The lowest monthly rainfall in the sultanate occurs in November, October, June and May, and these months collectively account for only 18.2 per cent of the yearly rainfall.

Mountains in northern Oman experience an average monthly rainfall of 11.8mm. Approximately 53.9 per cent of the rainfall occurs from January to April, and summer rain (July–August) accounts for 23.3 per cent of the rainfall.

Rainfall patterns in the Batinah plains and the northeast coast are quite similar.

In both locations, the majority of rainfall (90.3 per cent in the Batinah plains and 81.2 per cent in the northeast coast) occurs between November and April.
