This map visualizes California vegetation stress by comparing current satellite observations to a 6-year historical baseline. Red indicates vegetation more stressed than normal; green indicates healthier than normal conditions.

Click anywhere in California to get the exact vegetation stress anomaly score and current drought classification for that location.

Note: Satellite data typically lags the current date by 2–4 weeks or longer. The anomaly values shown are based on the most recent available composite, which may be from a previous calendar month.

Data updates every 16 days following the MODIS satellite composite cycle.
