MUMBAI, Sept 30 (Reuters) - Monsoon rains in India were 10% above average in 2019 and the highest in 25 years as seasonal rainfall continued longer than expected, the weather department said on Monday.
Extra June-September monsoon rainfall will help farmers expand areas under winter-sown crops such as wheat, rice rapeseed and chick peas, improving their earning potential and helping revive tepid rural demand that has stung Indian economic growth.
The longer monsoon could also restock reservoirs and help replenish ground water, helping assuage water shortages in pockets of the country of 1.3 billion people.
But heavy rainfall in some areas has damaged summer-sown crops like cotton, soybean and pulses that are close to harvest.
The monsoon delivers about 70% of India's annual rainfall and determines the yield of rice, wheat, sugarcane and oilseeds, such as soybeans.
Farming accounts for about 15% of India's $2.5 trillion economy but employs more than half of its people.
"Even in the first half of October, above average rainfall is expected due to a delay in the withdrawal of the monsoon," said an official with the India Meteorological Department (IMD), declining to be named as he was not authorised to speak with media.
The monsoon generally begins in June and starts to retreat by Sept. 1, but rains have lasted longer this year, triggering fatal floods and killing hundreds of people.
Rains are unlikely to start receding before early October, more than a month later than usual, the head of the weather office said on Friday.
"Excessive rainfall wasn't of much benefit to summer crops due to erratic weather patterns, but it will help winter crops. Reservoirs are holding more water than normal," said Harish Galipelli, head of commodities and currencies at Inditrade Derivatives & Commodities in Mumbai.
The 2019 monsoon season got off to a bleak start with the driest June in five years and below-average precipitation in July, suggesting an initial prediction for lower than normal rainfall from the country's only private forecaster, Skymet, could come to pass.
The weather department had also said in May that rains this year would amount to 96% of the long-term average.
But August saw heavy rains and flooding in some states and the strong monsoon has stretched into this month.
Water levels in India's main reservoirs were at 89% of their storage capacity as on Sept. 27 against 74% a year earlier, government data shows. The average for the past 10 years is 72%.
