The record
Written from the 1 report below. Nothing here is unsourced.
- Parts of Tamil Nadu, including Chennai, have recorded unusually high summer-like temperatures this September.
- The Regional Meteorological Centre attributed the heat to a weak Southwest monsoon, lack of cloud cover, dry southerly winds, and the El Niño effect.
- Several stations, including Erode, Palayamkottai, Vellore, Tiruchi and Madurai, crossed 40°C earlier this month, and Tiruchi recorded 39.5°C, the State's highest, for the third consecutive day.
- Nungambakkam in Chennai recorded 38.1°C, the city's second highest September maximum in a decade, against an all-time September record of 38.9°C set in 1883.
- Increased rainfall from Friday, triggered by a trough up to the Gulf of Mannar, is expected to cool temperatures, and rain over the coming weeks may narrow the rainfall deficit.
What to watch next
- Whether rainfall from Friday reduces temperatures in north and interior Tamil Nadu, including Chennai and Vellore.
