The California coastal valleys of Salinas and Santa Maria typically remain the 
major sources of supply of lettuce through mid-October. Huron, which is located on the west side of the San Joaquin Valley, usually fills the lettuce supply gap in late October through much of November before harvest switches to the desert in California and Arizona. Some of the hardier items, such as broccoli and cauliflower, will continue in the Salinas area until the shift to the desert (California’s Imperial Valley and the Yuma, AZ area) around Thanksgiving.
There has been strong shipments of California vegetables since early summer. A primary reason is the extreme drought in the Midwest and the upper Midwest, which knocked out some home-grown crops.
Additionally, there was the hurricane that hit New Orleans and continued on through the South hitting Kentucky and Tennessee and knocking out some of those local tomato harvests. It all helped to benefit shipments of California tomatoes.
Berries
Blackberry shipments are winding down on California’s Central Coast, but raspberries could go through the end of October.
Blackberries loadings tend to decline by the end of September and are finished by mid-October as the shipments out of Mexico pick up.
California strawberry and raspberry shipments have provided some problems for haulers over the summer. Both are more delicate fruit, especially raspberries. Much of this can be blamed on the horrendous summer heatthan began in June and continued through most of August. Good quality fruit results in more shipments (due to consumer demand), plus truckers deal with fewer rejections. Obviously the quality of the fruit has improved since the heat has subsided. The fruit holds up better when shipped.
