NEW DELHI: India's Kerala state has closed all schools and colleges until Monday due to scorching temperatures, urging people in the coastal region to limit exposure to the sun and take care to prevent wildfires.

With most parts of India reeling from high temperatures, the weather department has forecast an unusually high number of heatwave days for April to June, as the country stages a general election that has seen a low voter turnout.

Heatwaves are rare in Kerala and data from the India Meteorological Department (IMD) shows that the state recorded five heatwave days in April.

Referring to the current El Nino weather pattern, the IMD said yesterday that El Nino years typically have more heating, with hot and dry weather in Asia and heavier rains in parts of the Americas.

Fewer thunderstorms and an anti-cyclonic circulation near India's southeastern coast were causing heatwaves, the IMD said.

Kerala's state government today directed people to minimise exposure to the sun and urged authorities to monitor situations to avoid fires.

With several districts issuing heatwave warnings, the government asked all educational institutions to be shut till Monday.

Heatwaves have forced school closures in parts of Asia and North Africa too, widening learning gaps between developing nations in the tropics and developed countries, experts told Reuters.

Local media reported that at least two people died earlier this week in Kerala, but authorities are yet to confirm if their death was due to extreme heat.

Today, temperature in state capital Thiruvananthapuram touched 35°C but the IMD said it felt like 46°C due to high humidity.

Soaring temperatures and dry spells have caused frequent forest fires in other parts of India, and the blazes have been worsened by people burning the forest to collect a flower used to brew alcohol in Odisha state.
