Weather – Tamil Nadu Faces Above-Normal Temperatures as Humid Conditions Continue
Weather – Tamil Nadu is expected to witness a further rise in daytime temperatures over the next few days, with the Regional Meteorological Centre (RMC) in Chennai forecasting that maximum temperatures may remain 3 to 4 degrees Celsius above the seasonal average until July 16. Although the southwest monsoon is active across several parts of India, its weak influence over Tamil Nadu has resulted in prolonged hot and humid weather across many districts.
Weak Monsoon Keeps Heat Levels Elevated
As July progresses, several regions in the state continue to experience weather conditions more typical of the peak summer season than the monsoon. Limited rainfall across large parts of Tamil Nadu has reduced the cooling effect usually associated with this time of year. According to meteorologists, the subdued southwest monsoon has prevented widespread showers, allowing daytime temperatures to remain unusually high.
The weather department has also cautioned that coastal districts of Tamil Nadu and the Union Territory of Puducherry are likely to face uncomfortable conditions due to the combination of high temperatures and increased humidity. Residents have been advised to avoid spending extended periods outdoors during the hottest part of the day and to drink sufficient water to reduce the risk of heat-related illnesses.
Several Districts Record High Daytime Temperatures
Recent observations highlight the intensity of the prevailing heat across the state. On Sunday, as many as 14 weather stations recorded maximum temperatures of 37.8 degrees Celsius or higher.
Vellore reported the highest temperature at 41.7 degrees Celsius, making it the hottest location in Tamil Nadu. Madurai Airport registered 41.1 degrees Celsius, while Madurai city recorded 40.6 degrees Celsius. Temperatures reached 40 degrees Celsius at both Tiruttani and Chennai’s Meenambakkam observatory.
Other major locations also experienced elevated temperatures. Tiruchy and Cuddalore each recorded 39.4 degrees Celsius, while Palayamkottai and Chennai’s Nungambakkam weather station reported 38.9 degrees Celsius.
Heat Persists Across Multiple Regions
The hot spell extended beyond a few isolated districts. Nagapattinam, Erode, Karur Paramathi, Parangipettai and Namakkal all registered temperatures exceeding 38.6 degrees Celsius, indicating that above-normal heat has affected a broad stretch of the state.
Weather experts attribute these conditions to the lack of widespread cloud cover and insufficient rainfall, both of which normally help moderate daytime temperatures during the monsoon season. In the absence of these weather systems, solar heating has remained strong, pushing temperatures well above the seasonal average.
Limited Rainfall Expected in Western Ghats
The Regional Meteorological Centre has predicted light rainfall over districts along the Western Ghats on Tuesday. While these showers could offer temporary relief in hilly areas, forecasters do not expect them to bring any significant reduction in temperatures across the plains.
Most interior and coastal regions are therefore likely to continue experiencing warm afternoons accompanied by high humidity until at least July 16. Weather officials have advised people, particularly children, older adults and those working outdoors, to remain cautious during peak afternoon hours and take necessary precautions against heat exposure.
Authorities continue to monitor weather conditions as the state awaits stronger monsoon activity that could provide broader relief from the ongoing spell of above-normal temperatures.
