Note that USDA utilizes various parameters to forecast cattle stress. The parameters included by USDA in forecasting are Temperature, Humidity, Wind Speed and Solar Radiation. Please visit USDA's website to learn how USDA forecasts heat stress. The Cattle Stress recent and past maps are created using only Temperature and Humidity, and is based on University of Oklahoma's cattle stress model. Please visit their website
to learn how University of Oklahoma's AgWeather website forecasts heat stress.

Cattle Stress in the last few days







When the Cattle Heat Stress Index is at 71 or below, cattle are in the thermal neutral zone,
meaning that they are comfortable and production will not be sacrificed due to severe environmental conditions.

Values ranging from 72-79 indicate “Mild Stress.”
This is often when cattle will move to shade to cool themselves.
Livestock managers should monitor the weather and prepare to take action if conditions worsen.

Heat Stress Index values ranging from 80-89 indicate a “Moderate Stress.”
This is the time to implement management strategies to help reduce cattle stress.

Values above 90 indicate “Severe Stress.”
