South Africa is experiencing a decrease in macadamia nut production due to heavy rainfall and a cool summer, with the forecast at 76,753 tons, a 3.7% drop from last year and a 12% decrease from the season's initial forecast. Kenya's production may also fall short of expectations, but is expected to surpass last year's production by 3.5%, largely due to China's increased sourcing of macadamia nuts in shell following the temporary export ban's lifting. Australia's production has seen a 5% increase from last year, but falls short of the initial forecast, with a total of 50,830 tons harvested despite initial weather challenges.
