Tunisia is expected to experience a shift in weather conditions on Tuesday, June 16, 2026, moving from generally summery conditions to increasing atmospheric instability. The National Institute of Meteorology (INM) forecasts cloud cover across most regions, thickening throughout the afternoon. This will likely result in thunderstorms developing in several areas of the country. While the morning will be characterized by typical summer weather, residents should prepare for potential disruptions later in the day. The INM has not specified the severity or precise locations of the expected storms, but advises monitoring updates. This forecast signals a break from consistent sunshine and a potential for localized heavy rainfall.
