The Regional Meteorological Centre (RMC) predicts normal to above-normal rainfall for much of Tamil Nadu this August, though heat levels may rise in several districts.

Key Takeaways

  • Coastal Tamil Nadu is expected to see normal or above-average rainfall.
  • Western Ghats regions may experience rainfall deficits.
  • Maximum temperatures in Tamil Nadu and Puducherry may stay above normal.
  • The Southwest monsoon is expected to intensify in the first half of August.

According to the latest outlook from the Regional Meteorological Centre (RMC), most parts of the state are poised to receive normal or even above-normal rainfall throughout August. However, a geographical divide is expected, as the Western Ghats region may witness a deficit in precipitation compared to the rest of the state.

The meteorological department has noted that while interior parts may see steady rain, coastal Tamil Nadu is likely to benefit from more significant rainfall spells. This comes as the Southwest monsoon is predicted to pick up pace, particularly during the first fortnight of the month.

Why This Matters

BozokMedia analysis shows that this weather pattern presents a dual challenge for the state. While the rainfall will be a boon for coastal agriculture, the predicted rise in maximum temperatures and humidity could impact public health and energy consumption in urban centers like Chennai and Puducherry.

The probabilistic outlook suggests favorable conditions for wet spells in the eastern parts, despite a national trend of below-normal rainfall.

Current data indicates that since June 1, the state has received only 10 cm of rainfall, marking an 18% deficit compared to normal levels. Districts such as Ariyalur, Ramanathapuram, Tiruchi, Vellore, and Nagapattinam are currently grappling with a seasonal rainfall shortage.

Did You Know?: Even when rainfall is 'normal', high humidity levels can make the perceived temperature feel much hotter than the actual thermometer reading.
