Pollen in Pomona, CA

About pollen in Pomona

Pomona is enjoying a quiet stretch when it comes to pollen today. Tree pollen is sitting at essentially nothing, and there's no meaningful activity from grass or weed sources either. For most people, including those who usually deal with seasonal sensitivity, today should be comfortable with little to no irritation from airborne pollen. Looking ahead, conditions are expected to hold steady with tree pollen remaining minimal over the next few days. This lines up with the season — local trees like Albizia, Tristaniopsis, Pyrus, Maple, and Hickory typically release their pollen in spring, so by midsummer their activity has largely wound down. It's a good stretch for anyone sensitive to tree pollen to catch a break before other seasonal triggers, such as late-summer weeds, potentially become more relevant.
