Very Low Pollen in Costa Mesa, CA

About pollen in Costa Mesa

Pollen levels across Costa Mesa are minimal today, with the overall index sitting at Very Low. Grass is the main contributor at a Very Low reading, while tree pollen has dropped to none and weed pollen is unmeasured. The five-day outlook holds steady, with grass expected to stay at Very Low throughout. That flat trend fits the season, as late spring and early summer typically favor grass over trees. Local ornamentals like Washingtonia, Phoenix, and Trachycarpus palms, along with Tristaniopsis and Syagrus, are well past their main pollen window now and aren't adding to the air.
