Very Low Pollen in Fullerton, CA

About pollen in Fullerton

Pollen levels around Fullerton are quiet today, with tree pollen sitting at a very low level. Trees such as Washingtonia, Syagrus, Cupaniopsis, Melaleuca, and Maple are contributing little to the air right now, so most people should be able to go about their day without much irritation, even those who tend to be sensitive. Looking ahead, conditions are expected to hold steady over the next several days, with tree pollen staying at that same low point. This tracks with the season, since the heavier tree pollen release typically happens back in spring, and by midsummer it has largely tapered off for these local species. For now, allergy sufferers can expect a relatively easy stretch with little change on the horizon.

What to do today

• Pollen is low today, so it's a good day for outdoor activities.
