Meteorologists forecast weaker than normal monsoon.

SINGAPORE -- Early signs of hot, dry weather caused by El Nino are threatening food producers across Asia, while American growers are counting on heavier summer rains from the weather phenomenon to alleviate the impact of severe drought.

Soil is drying in Pakistan and India, which is expected to hamper summer crop planting, while El Nino is also forecast to blunt the impact of South Asia's crucial June-September monsoon season.

"We are looking at longer term dryness in Australia from now until at least August," said Chris Hyde, a meteorologist at US-based Maxar. "The seasonal outlook in India is a weaker than normal monsoon for the entire country, extending into Pakistan."

El Nino, a warming of water surface temperatures in the eastern and central Pacific Ocean, is expected to develop in the coming months, according to meteorologists. The impact of the phenomenon typically causes hot, dry weather across Asia and Australia while bringing heavier-than-normal rainfall to the southern US and southern South America.

As El Nino looms, wheat output in Australia, the world's second-largest exporter of the grain, is expected to take a hit from dry weather, while palm oil and rice production is likely to suffer in Indonesia, Malaysia and Thailand, forecasters and analysts said.

Lower production of cereals and oilseeds in Asia because of El Nino is likely to heighten food inflation worries for some of the world's most vulnerable consumers, dashing hopes for further relief from lower prices in recent months.

Even if the weather pattern ends up boosting crop output in the Americas, the impact in Asia could reverberate across global food markets. Wheat prices dropped to two-and-half year lows this week, while corn and soybeans have eased from multi-year peaks set in 2022, when the Russia-Ukraine war and Covid disrupted world...
