How is Thoothukudi's AQI calculated?
The Air Quality Index combines PM2.5, PM10, NO₂, SO₂, CO and O₃ readings from CPCB-monitored stations into one 0–500 score, using whichever pollutant reads worst as the overall number rather than an average of all of them. Today the dominant pollutant driving that number in Thoothukudi is CO. Thoothukudi's current AQI of 382 falls in the "Very Poor" band (301–400).
Is Thoothukudi's air quality safe today?
Not fully - Thoothukudi is at Very Poor today (AQI 382). Avoid outdoor exertion. Wear a mask outside; sensitive groups should stay indoors.
Why does 28°C feel like 31°C in Thoothukudi?
"Feels like" factors in humidity and wind on top of the actual air temperature. At 78% humidity and 22 kph wind, Thoothukudi's air right now feels hotter than the thermometer reading - high humidity slows sweat evaporation, so your body sheds heat less efficiently than the raw air temperature alone would suggest.

Petrol is ₹108.44/L, diesel ₹100.30/L, for Thoothukudi. Fuel prices are revised daily and can vary slightly by station. The base crude and refinery cost is the same nationwide - state VAT and cess are what make petrol cheaper or pricier just across a state line.
Why does Thoothukudi's gold price match the national rate?
