Soaring temperatures in India

As temperatures continue to soar across northern and central India, with mercury rising to 45 degrees in several places, many people have started talking about “Nautapa”. Rooted in Indian astrology and weather folklore, the nine-day period is considered to bring the most intense heat days around late May and early June every year.

What is Nautapa?

Nautapa is a nine-day period believed to bring the hottest days of summer in India. The term comes from the Hindi words “nau” (nine) and “tapa” (heat). It usually begins around May 25 or May 26 every year. According to traditional Hindu astrology, Nautapa begins when the Sun enters the Rohini Nakshatra (a prominent star/constellation). During this phase, the Sun’s rays are considered especially intense, falling almost vertically on the Northern Hemisphere, leading to soaring temperatures in the region.

What does science say?

While the India Meteorological Department has already warned of heatwaves, it does not officially recognise Nautapa as a scientific weather event. However, late May is naturally one of the hottest periods before monsoon winds arrive, which explains the extreme temperatures.
