Pollen in Fullerton, CA

About pollen in Fullerton

Pollen activity in Fullerton is essentially quiet today. Tree pollen, the only category being measured right now, is reading at none, so most people should notice no irritation from it. This is a welcome break for anyone sensitive to airborne allergens. Looking ahead, conditions are expected to hold steady at this low level over the next few days. This fits the seasonal pattern for mid-November, well past the spring peak when trees like Geijera, Ficus, Jacaranda, Pistacia, and Lagerstroemia typically release the bulk of their pollen. With grass season behind us and ragweed winding down as well, this is generally a calmer stretch for allergy sufferers in the area.

What to do today

• Pollen is minimal today, so it's a great time to be outside.
