Current Climate


This page presents Sudan'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. 

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.

Sudan experiences mean annual temperatures between 26°C and 32°C, with summer temperatures in the north often exceeding 43°C. Rainfall in Sudan is unreliable and erratic, with great variation experienced between northern and southern regions. Northern regions typically experience virtually no rainfall (less than 50 mm annually), central regions receive between 200 mm and 700 mm per year, and some southern regions experience more than 1,500 mm annually. Most rainfall occurs during the rainy season from March to October, with greatest concentration between June and September.
