Chennai Weather: Light Rain and Persistent Heat

In Chennai, the weather forecast suggests light to moderate rainfall on Monday, with hot and humid conditions expected to persist until Tuesday. A marginal drop in temperature may bring brief relief midweek.

• Maximum temperature: ~38°C
• Minimum temperature: 28–29°C

Heatwave-Like Conditions in Interior Tamil Nadu

Despite incoming rainfall in some regions, above-normal temperatures continue in interior districts, contributing to discomfort and heat stress.

Recent Maximum Temperatures (as of Sunday):

• Puducherry: 40°C
• Erode & Madurai Airport: 39.6°C
• Vellore: 39.4°C
• Palayamkottai: 39.2°C
• Karur Paramathi: 43.8°C (4.8°C above normal)

These figures indicate a 2–4°C increase over normal seasonal temperatures in several locations.

Why This Weather Pattern?

The current rainfall activity is influenced by:

• An upper air cyclonic circulation over the southeast and east-central Bay of Bengal
• Moderate westerly and south-westerly winds in the lower troposphere

These atmospheric changes are bringing rain to some districts while others continue to face persistent heatwave conditions.

General Forecast Until June 14

• Light to moderate rainfall is expected in Tamil Nadu, Puducherry, and Karaikal through June 14
• However, daytime temperatures may remain 2–3°C above normal in many interior districts, keeping conditions hot and uncomfortable

Residents across Tamil Nadu and Puducherry should stay alert to changing weather conditions, especially those in heat-prone areas. The RMC continues to monitor developments and issue updates as needed.
