The 2015 California walnut production forecast is at a record 575,000 tons, up 1 percent from 2014's production of 570,000 tons. This forecast is based on the 2015 Walnut Objective Measurement (O.M.) Survey, officially conducted by the National Agricultural Statistics Service from August 1 through August 29, 2015.

Despite a lack of chilling hours and a drought that continued to impact California, the 2015 walnut crop forecast is at a record level. Relatively mild summer temperatures have benefitted the crop. Growers used surface water where available and groundwater when necessary to provide adequate water supply to the trees. Crop quality is reported to be excellent with low disease and insect pressures.

Percent of sound kernels in-shell was 98.5 percent Statewide. In-shell weight per nut was 22.7 grams and the average in-shell width suture measurement was 32.8 millimeters. The in-shell cross-width measurement was 32.8 and the average length in-shell was 38.5 millimeters. All of the sizing measurements were above previous year.
