Weather – Tamil Nadu Temperatures Likely To Rise As Light Rainfall Forecast
Weather – Tamil Nadu is expected to experience a gradual increase in daytime temperatures over the next few days while some southern coastal districts may receive scattered light rainfall.

The Regional Meteorological Centre in Chennai has indicated that maximum temperatures across Tamil Nadu are likely to rise slightly in the coming days. According to the latest forecast, the mercury may increase by around 2 degrees Celsius until March 15. At the same time, a developing atmospheric circulation over the Bay of Bengal could bring light rainfall to certain southern coastal areas of the state.
Atmospheric System Over Bay Of Bengal Influencing Weather
Meteorologists said a low-level atmospheric circulation currently persists over the southwest Bay of Bengal. This weather system is expected to influence conditions along parts of the Tamil Nadu coastline, particularly in districts located in the southern region.
Due to this development, isolated locations in the southern coastal belt could receive light rainfall on Thursday. Officials noted that while the system is not expected to intensify significantly, it may continue to affect weather patterns in nearby coastal districts over the next several days.
Weather experts explained that such atmospheric circulations are relatively common during the transition from winter to the early summer season in southern India. These systems often result in brief spells of light rainfall while temperatures gradually climb.
Light Rainfall Expected In Some Coastal Areas
Forecast models suggest that isolated places along the southern coast could experience very light rainfall between now and March 16. While rainfall activity is expected to remain limited, meteorologists believe a few locations may receive moderate showers around March 17 if the weather system maintains its influence.
Despite the possibility of rain in certain coastal districts, most parts of Tamil Nadu are expected to continue experiencing warm daytime conditions. Inland regions are unlikely to see significant rainfall during this period.
Officials emphasized that rainfall, where it occurs, will likely be scattered and short-lived rather than widespread.
Gradual Increase In Daytime Temperatures
The Meteorological Department also expects temperatures across the state to rise modestly over the next few days. Daytime maximum temperatures may increase by up to 2 degrees Celsius in several regions.
Such a rise is considered typical during the pre-summer period when heat levels slowly begin to intensify across southern India. During this seasonal transition, clear skies and increasing solar radiation often lead to warmer daytime conditions.
Weather specialists noted that while the temperature increase is noticeable, it remains within the normal range for this time of year.
Weather Conditions In Chennai
In the state capital Chennai, the forecast suggests partly cloudy skies on Thursday. The city is likely to record a maximum temperature of around 35 degrees Celsius, according to the Regional Meteorological Centre.
Humidity levels are also expected to remain relatively high due to the city’s coastal location along the Bay of Bengal. This combination of humidity and warm temperatures may make the weather feel slightly warmer than the actual recorded temperature during daytime hours.
Evening conditions, however, are expected to remain relatively comfortable compared with the afternoon heat.
Advisory For Residents During Warmer Days
Weather officials have advised residents across Tamil Nadu to take basic precautions as temperatures gradually increase. Authorities recommend staying hydrated, limiting outdoor activity during peak afternoon hours, and avoiding prolonged exposure to direct sunlight.
Although the forecast temperature rise is not considered extreme, precautions can help prevent heat-related discomfort as the pre-summer conditions begin to develop.
For now, Tamil Nadu is expected to experience a mix of warm temperatures and occasional light rainfall along the southern coastline. Meteorologists will continue to monitor the atmospheric circulation over the Bay of Bengal and provide updated forecasts if weather conditions change.
