Is 27 October School Holiday?
The northeast monsoon has intensified across Tamil Nadu, with the India Meteorological Department (IMD) issuing severe weather alerts for multiple districts. A low-pressure area in the Bay of Bengal is likely to intensify into Cyclone Montha by October 27, bringing widespread heavy to very heavy rainfall across coastal and interior districts.
Although no blanket statewide holiday has been declared so far for October 27, 2025, district administrations are closely monitoring conditions, especially in coastal and delta zones. Schools in rain-affected districts may declare closure on a district-wise basis, depending on rainfall severity and local safety conditions.
IMD Rainfall Forecast for Tamil Nadu
According to IMD, the following areas are expected to receive intense rainfall and thunderstorms over the weekend leading into Monday :
North coastal districts: Chennai, Tiruvallur, Chengalpattu, and Kanchipuram are likely to witness heavy to very heavy rainfall.
Delta districts: Nagapattinam, Tiruvarur, Thanjavur, and Mayiladuthurai may receive continuous downpours.
Southern Tamil Nadu: Ramanathapuram, Sivagangai, and Thoothukudi could experience moderate to heavy showers.
Western districts: Coimbatore, Nilgiris, and Erode may face scattered rainfall due to monsoon flow.
The IMD has placed Tamil Nadu and Puducherry under a Yellow Alert, with an upgrade to Orange Alert possible by Sunday if wind speeds and rainfall increase further.
Possible School Closures by District
District Collectors have been authorized to declare local holidays where necessary. Based on current rainfall distribution and flood-prone areas, possible school holidays may be declared in the following districts if heavy rain continues through Sunday night:
Chennai, Tiruvallur, Chengalpattu, and Kanchipuram: Expected heavy rainfall from the approaching low-pressure belt.
Cuddalore, Villupuram, and Puducherry regions: Moderate to heavy rain predictions with waterlogging concerns.

Salem, Namakkal, Erode, and Dharmapuri: Rain warnings due to monsoon circulation in western zones.
Madurai, Dindigul, Theni, and Tirunelveli: Scattered showers likely, but school operations will depend on local rainfall.
