FROM THE FIELDS: WEST COAST HEAT WAVE

August 19, 2025

All major West Coast growing regions such as Salinas, Santa Maria, and Oxnard, California are experiencing a heat wave that will intensify this weekend and carry into mid-next week.

Salinas Valley is expecting temperatures in the mid-80°s near the coast and inland temperatures facing several days of 105°-112°. Santa Maria and Oxnard temperatures will remain in the mid-70°s to upper 80°s. As a result, harvesting crews will start much earlier over the next week to avoid peak temperatures. Markon inspectors will monitor product closely for heat-related challenges that may include, but are not limited to:

  • Bolting/seeder
  • Bruising/soft texture in strawberries
  • Dehydration/wilting
  • Discoloration/yellowing leaves, particularly in baby leaf items that are sensitive to rapid temperature fluctuations
  • Growth cracks
  • Hollow core and pin rot in broccoli
  • Increased disease/plant virus pressure
  • Increased insect pressure
    • Aphids
    • Diamondback Moth
    • Thrips
  • Internal burn/tip burn
  • Shortened shelf-life in commodity and value-added lettuce and tender leaf items

Markon inspectors will continue to work with suppliers, evaluating commodity and value-added items while working to minimize heat-related challenges. As always, cold chain management throughout the supply chain is critical for maximizing the quality and shelf-life of perishable produce items.
