Rain succeeds heat in West Coast growing regions

Markon Cooperative BB #:123315 released this West Coast weather update October 20, 2026:

A cooler, unsettled weather pattern has replaced last week’s heat across key West Coast growing regions.

Sporadic showers, increased humidity, and prolonged morning moisture are forecast for most regions starting Wednesday, October 21, and continuing through Thursday, October 22. Markon is working with growers to pack orders ahead where necessary to ensure 100% fulfillment. Harvesting crews will take measures to keep field-packed boxes as clean and dry as possible.

• Salinas Valley and 0.50″ to 1.25″ across Santa Maria and Oxnard growing areas
• Dry conditions will return by the weekend

Field Outlook

Production and loading delays can be expected over the next several days, pending field conditions, particularly in Salinas, Santa Maria, Huron, and Oxnard.

Rain-related challenges that may develop, including but are not limited to:

• Bottom rot, decay, increased mildew pressure, premature pinking, shortened shelf-life in commodity and value-added lettuce items
• Bruising, decay, soft texture, rain damage, reduced yields, and shortened shelf life in strawberries
• Pin rot, decay, bead discoloration, hollow core, increased mildew pressure, and shortened shelf life in broccoli
• Black mold and shortened shelf life in cauliflower

Reduced yields and variable case weights remain possible in affected row crop commodities.

Markon inspectors will closely monitor commodity and value-added lettuce and tender leaf items and will update further as needed. Ordering for quick turns is recommended; strict cold-chain management remains critical to maximizing product quality and shelf life.
