The weather in Dehradun, Uttarakhand, during 14 and 15 September 2026 is expected to remain generally warm, with periods of sunshine and a possibility of thunderstorms. September is part of the retreating phase of the monsoon season in the region, so weather conditions can change quickly, with sunny periods followed by cloud development and brief showers or thunderstorms.

During thunderstorms, it is advisable to avoid exposed outdoor areas and seek shelter inside a safe building. Drivers should also exercise caution if rain occurs, as wet roads and reduced visibility can make travelling more difficult.
