India's crops seen safe from widespread drought in 2013
The El Nino weather phenomenon was unlikely to influence monsoon rains in the first half of the June-September season, the weather group said.
El Nino, an abnormal warming of waters in the equatorial tropical Pacific, is associated with poor rains or a drought-like situation in southeast Asia and Australia.
"El Nino is going to be neutral and continue to remain so," said Rupa Kumar Kolli, head of the climate applications and service division of the World Meteorological Organisation.
India's weather office rates as normal rainfall between 96 and 104 percent of a 50-year average of 89 centimetres during the entire four-month season. The last drought with rains below this range was in 2009 and before that, in 2004.
Last year, a late revival of the monsoon in the second half of the June to September rainy season helped India escape widespread drought, and the season ended with rainfall at 92 percent of the long period average.
But seven states in the country's south and west, including key sugar producer Maharashtra and cotton-producing Gujarat, had very low rainfall and are still battling acute drought that has hammered farmers' incomes and made this year's rains critical.
