Rain in parched areas of Western and South Australia and more expected in coming days could add as much as a million tons to the country's wheat harvest, analysts said this week.
The larger wheat production would help boost global supply after crop losses in Russia pushed Chicago futures prices to 10-month highs. Australia is a major exporter of wheat, barley and canola, and all three crops would benefit from the rains, Reuters said.
While Australia's eastern regions have had plenty of moisture, in the west and south many farmers have been planting seeds into dry earth and hoping for showers.
"Without the rain, we were heading for a reduction for wheat of half a million tons or more in Western Australia," said Ole Houe, head of advisory services at IKON Commodities in Sydney.
"With the rain, we might even add half a million," he said. "Our forecast is still more than 30 million tons and that number is probably growing now rather than shrinking."
Rain in Western Australia would also stabilize the canola crop since the state accounts for nearly half the country's canola production.
Farmers will also be encouraged to sow more seeds, which could result in Australia's planted area being up to 5% larger than if no rain had come, said Andrew Whitelaw at agricultural consultants Episode 3 in Canberra.
Precipitation this week and next should add between 500,000 and a million tons to the national wheat harvest, Whitelaw said, though he added that some eastern areas were now at risk of becoming too wet.
Much of Western Australia's crop belt and almost all of South Australia's received rain this week, and more widespread rain should fall in the coming eight days, particularly in the west and the east, Australia's weather bureau said.
In a long-range forecast this week, the bureau said June would likely see below-median rainfall in most crop areas but July-through-September should be wetter than average, boosting hopes for the harvest.
Australia's agriculture ministry is due to issue a quarterly crop report with its expectations for production on Tuesday.

Scientists: Melting Sea Ice in Antarctica Causes Ocean Storms

The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday.
Scientists know that the loss of Antarctic sea ice can diminish penguin numbers, cause ice shelves to melt in warmer waters, and impede the Southern Ocean from absorbing carbon dioxide, AFP reported.
But this new research, published in the peer-reviewed journal Nature, explores another consequence: increased heat loss from the ocean to the atmosphere, and an associated rise in storms.
Since 2016 there has been a large-scale reduction in Antarctic sea ice, but nothing like 2023 when a record amount failed to reform over the winter.
For this study, Simon Josey of the UK's National Oceanography Center and colleagues focused on three regions that experienced unusually high levels of sea-ice retreat that year.
Using satellite imagery, ocean and atmospheric data, and wind and temperature measurements, they found some newly ice-free areas experienced double the heat loss compared to a stabler period before 2015.
This was accompanied by "increases in atmospheric-storm frequency" over previously ice-covered regions, the authors found.
"In the sea-ice-decline regions, the June–July storm frequency has increased by up to 7days per month in 2023 relative to 1990–2015."
The loss of heat caused by reduced sea ice could have implications for how the ocean circulates and the wider climate system, the study added.
Oceans are a crucial climate regulator and carbon sink, storing more than 90 percent of the excess heat trapped near Earth's surface by greenhouse gas emissions.
In particular, sea-ice retreat could mean changes in how a deeper layer of cold, dense Antarctic bottom water absorbs and stores heat.
The authors said further in-depth analysis of possible climate impacts were needed, including if sea-ice retreat could have even further-reaching consequences.
"Repeated low ice-cover conditions in subsequent winters will strengthen these impacts and are also likely to lead to profound changes further afield, including the tropics and the Northern Hemisphere," it said.
