Heat Advisory - Western Growing Regions

Mon, March 16th, 2026

Dear Ole Tyme Customers:

An Excessive Heat Advisory is currently affecting key growing regions in Yuma, Arizona and Huron, California.

Daytime highs are forecasted to reach the low to mid-90s over the next 10 days, significantly above the typical March average of 68°F. These elevated temperatures are expected to accelerate crop maturity and impact normal harvest patterns.

Commodities Most at Risk

Romaine, Leaf Lettuce, Spring Mix – Increased risk of tip burn, internal burn, insect pressure, and shorter shelf life
Iceberg Lettuce – Lighter head weights and higher field culling
Broccoli & Cauliflower – Smaller crowns/heads and accelerated maturity
Celery – Lighter stalk weights and variable quality
Green Onions & Cilantro – Reduced shelf life in prolonged heat

What This Means for Harvesting

Crews are adjusting schedules to start earlier and finish sooner for safety
Shortened harvest windows may lead to reduced daily volumes
Faster crop maturity may create short-term supply fluctuations

Potential Supply Impacts

Decreased harvest volumes
Lighter carton weights (especially lettuce and brassicas)
Increased insect pressure and quality control culling
Market fluctuations as supply adjusts to rapid maturation

We are actively communicating with growers and shippers and will continue to monitor field conditions closely. Further updates will be provided as this heat event develops.

If you have any questions, please reach out to your Sales Representative.

Thanks,

Ole Tyme Produce
