NEW DELHI, Sept 1 (Reuters) - India is likely to receive above average rainfall in September, the state-run weather office said on Wednesday, helping millions of farmers who had to endure patchy rains in July and August.
Monsoon rains were 10 percent above average in June.
"According to critical weather parameters, rains are most likely to be above normal in September this year," Mrutyunjay Mohapatra, Director General of the India Meteorological Department (IMD), told a news conference.
The IMD defines average, or normal, rainfall as between 96 percent and 104 percent of a 50-year average of 88 cms (34 inches) for the four-month season beginning in June.
After lashing the southernmost Kerala coast on June 3, the monsoon spread to two-thirds of India by the end of the first half of the month, nearly 15 days earlier than expected. And then it tapered off in the third week of June.
Despite a brief revival, monsoon rains continued to be weak in July and August.
As the monsoon turned erratic in July and August, India's overall rains were 9 percent below average since the four-month rainy season began in June, Mohapatra said.
"Considering the expected above normal rainfall activity during September 2021, the current deficiency of 9 percent in seasonal rainfall during June to August is very likely to reduce and accumulated seasonal rainfall during June 1 to September 30, 2021, is very likely to be around the lower end of the normal," he said.
In June, the IMD said India was likely to receive average monsoon rains this year, boosting expectations for larger farm output amid a devastating second wave of COVID-19 infections.
Nearly half of India's farmland gets no irrigation and is dependent on the annual rains from June to September. Farming accounts for nearly 15 percent of the economy, Asia's third-biggest sector, but sustains more than half of a population of 1.3 billion.
