Chennai may simmer down today


The past week of hot and unpleasant weather may end on a cooler note.

With the southwest monsoon picking up pace in neighbouring states this week, cool weather in Chennai may prevail on Sunday. The Nilgiris region will experience rainfall for the next few days.

An upper air trough over north Bay of Bengal that extended till the city had contributed to Saturday’s cloudy weather. The soaring day temperature, which touched 38 degree Celsius — three degrees above average — on Friday, came down to 35.2 degree Celsius on Saturday. While murky skies brought drizzle in some areas during early morning, it did not translate into showers.

Officials of the meteorological department said clear skies and a delay in the onset of sea breeze had led to a rapid rise in the day temperature over the past few days. Last year, the city experienced the hottest day of the month on July 2, with the mercury level touching 38.3 degree Celsius.

Coastal areas like Chennai usually get rainfall due to convective activity triggered by sea breeze, they said. Going by the statistics, Chennai district has, since June 1, received 167 mm of rainfall against the normal of 119 mm.

Y.E.A. Raj, former deputy director general of meteorology, said residents need not worry over the shortfall in rains as thunderstorms often bring in up to 6 cm of rainfall in a single day during July, compensating for the lack of rainy days. “The volume of rainfall increases gradually in August and September. We get 70 per cent of southwest monsoon rains in August and Septemberthese months,” he said.
