California Crop Weather: Grape harvest continues

California Crop Weather: Grape harvest continues

The latest California Crop Weather report from the California Field Office of the National Agricultural Statistics Service.


Weak high pressure brought dry and mild weather to California at the start of the week (Sept. 13).  The high pressure shifted eastward Wednesday as a low pressure trough drove a Pacific frontal system towards the state.

By Thursday, low pressure settled over northern California while southern California remained under relatively higher pressure. Significant rain spread along the North Coast on Friday, in advance of the cold front which moved across the region over the weekend. The front brought heavy rain to the coast but much lighter amounts inland.

Temperatures in the northern California were generally cooler than normal for the second part of the week. Southern California remained dry with near seasonal temperatures through the week.

Field crops

Rice fields were drained and early-planted fields were harvested. Small grain harvests neared near completion in northern California. Dry bean harvest continued. Sudangrass was harvested for hay and silage. Corn fields were harvested for silage while grain fields dried down.

Alfalfa hay was cut and baled throughout California. Sunflowers were defoliated and harvested.

Cotton irrigation was near completion and fields were prepared for defoliation. Potato fields were prepared for harvest. Field preparation for fall crops continued with tillage and spray applications as needed.

Fruit crops

Valencia oranges were picked in the Central Valley and along the southern coast. The lemon harvest along the southern coast was nearly complete while light picking continued in the desert region.

The table and juice grape harvests were ongoing in the SJV while the raisin and wine grape harvests neared completion. The picking of wine grapes continued in the north and central coast counties.

Early Foothill pomegranates were picked in Tulare County. Field preparations were made for the upcoming strawberry nursery plant harvest in Siskiyou County. Orchards, where harvests were completed, were irrigated.

Nut crops

There was shaking and harvesting of almonds in the Central Valley. Irrigation, weed control, and ground preparations continued in walnut orchards as some hull splitting began.

Harvest spread to more pistachio orchards as the full-scale harvest is expected to begin in the upcoming week. Irrigation and pest control was ongoing in pecan orchards.
