California produces 99% of U.S. walnuts and nearly 50% of global trade, with production peaking at nearly 800,000 tons in 2020. The 2023 walnut production is forecasted to reach 790,000 tons, a 5% increase from 2022, as sales have been weak due to the impact of the pandemic and record high temperatures. Despite a decrease in walnut planting area in 2023, the committee is optimistic about the favorable climate and outlook for the 2023 harvest, which begins in September and lasts until November.
