UPDATE: Central Valley Heat

September 05, 2017

Excessive heat and high humidity in California’s San Joaquin Valley will impact multiple commodities over the next two weeks. Prolonged temperatures in the 109-111º range over the weekend impacted availability of crews as well as quality issues.


  • Markon First Crop (MFC) Lunch Bunch Grapes and Markon Essentials (ESS) Red Seedless Grapes are available
  • High temperatures and humidity will cause softness and mold issues
  • Supplies are expected to remain adequate through September


  • MFC Cantaloupe and Honeydew will be sporadic over the next two weeks
  • High humidity levels will cause over maturity, early breakdown and inconsistent sugar content
  • Sugar levels will range from 8-12 Brix, as compared to more consistent levels of 14-16 Brix


  • MFC and ESS Valencia Oranges are sporadic; packer label supplies are being substituted as needed
  • Persistently high temperatures are causing rind breakdown, softness, and stem end aging which has significantly decreased yields at pack out
    • Re-greening is a common issue this time of year due to heat
    • Shelf-life is shorter than normal; ordering for quick turns is recommended
  • Small sizes are extremely limited; demand exceeds supply
