Current Climate Climatology
This page presents Oman's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit. Other historical climatologies can be selected from the Time Period dropdown list. Data for specific coordinates can be downloaded for in the Data Download page.
Observed, historical data is produced by the Climatic Research Unit (CRU) of University of East Anglia. Data is presented at a 0.5º x 0.5º (50km x 50km) resolution.

Annual average rainfall ranges from 150 mm to 300 mm in the north while ranging from 50 mm to 150 mm in the south. There have been destructive tropical depressions, tropical cyclonic storms and severe cyclonic storms that have tracked toward Oman over the past decades from the north Indian Ocean and the Arabian Sea. Such storms typically occur during the pre-monsoonal period (May – June) and the post-monsoonal period (October – November).
