Lucknow, Apr 16 (IANS): In view of the fast rising summer temperatures, all schools in Lucknow district of Uttar Pradesh must start earlier at 7 a.m. and close latest by 12 noon, the authorities said on Saturday.

Managements of all schools will have to adhere to the new timing from Monday.

District Magistrate Raj Shekhar told IANS that the classes from nursery to sixth will have to be conducted from 7 a.m. to 11 a.m. and the classes above the sixth from 7 a.m. to 12 noon.

He said the order has been issued in view of the rising heat and forecast of harsher summer.

"Schools have also been asked to take measures to keep temperatures under control inside the class-rooms through necessary infrastructure changes," Shekhar said.

Other districts in the state are likely to follow suit, said sources.

The state government might also order early summer vacations which otherwise are scheduled to start in May.
