Pollen Forecast for Calpella, California

Concentration of pollen grains in the air for Saturday will be unchanged in the extremely low range. Although pollen is almost non-existent at this time, the budding trees are not far off. By the time the tree buds are noticeable, the new pollen is already in the air.

The amount of pollen in the air for Sunday will be rising but will still remain in the low range. This rise is a result of drier air. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.
