New Delhi: US weather agencies say that this time the effect of La Nina can be seen late. It is because of La Nina that India receives good rainfall during monsoon. Earlier it was expected that La Nina would come in August, but now it is likely to come in September. That is, this time La Nina is expected to be delayed by about a month. However, experts believe that due to the expected delay in La Nina, there will be no major reduction in monsoon rains in the June-September season. At present, monsoon is 3 percent less than normal across the country, but its figures are expected to improve in the next two weeks.La Nina will arrive one month late
The US National Oceanic and Atmospheric Administration (NOAA) has said that there is a 70% chance of La Nina in August-September-October. This means that La Nina may occur in September. Last month NOAA had said that there is a 65% chance of La Nina in August, but now it has come down to 48%.
What is La Nina?
La Nina causes the Pacific Ocean waters to become colder than normal, which changes the direction of winds and affects weather around the world. Unlike La Nina, the Pacific Ocean waters become warmer than normal during El Nino. La Nina causes good monsoon rains in India, while El Nino causes less rain.

'No need to worry about delay in La Nina'
Meteorologist and former secretary of the Union Ministry of Earth Sciences, M. Rajeevan, said, “There is no need to worry about the delay in La Nina. For the monsoon, it is necessary that the sea surface temperature in 'Nino 3.4' (an area of the Pacific Ocean) goes below zero. At present it is slightly above zero, but it is expected to go below zero by August. When this happens, the monsoon usually becomes strong.”
