August ended on the cooler side of average as an unseasonably cool system passed through California last weekend. Parts of Burney Basin, the Sierra Nevada, and the northern Sacramento Valley received about a tenth of an inch of precipitation with the system. Temperatures throughout most of inland California remained mild through the remainder of the month as a result of the low.

September began with a warm start as an area of high pressure built over California that enabled a trend of above average temperatures for the remainder of the week.  Triple digit temperatures in the Sacramento and San Joaquin valleys were occurred.

Inland southern California and the central/southern San Joaquin Valley (SJV) continued the triple digit temperature pace through Saturday. Above average temperatures persisted through the Labor Day weekend for interior California, but gradually cooled due to the tapering off of high pressure over the state.

The Bay Area and Salinas Valley experienced a short burst of hot temperatures on Wednesday due to offshore flow. Southern coastal California remained slightly below normal for most of the previous week.

Field crops

Rice fields headed while some fields were drained and water was added to others. Alfalfa was cut and baled. Potato fields were rolled and prepped for harvest in the northern areas while harvest continued in the SJV. Corn silage was harvested.

The garbanzo bean harvest continued in Fresno County while the safflower harvest was nearly complete. Sorghum continued to develop. Cotton fields were sprayed for aphids, lygus, and other pests.

Black-eyed bean fields in Tulare County received the last irrigation before harvest. Sunflower fields were harvested. Field operations continued with irrigation, ground preparation, and spray applications of fertilizer, herbicide, and insecticide, as needed.
