Black locust
Robinia pseudoacacia
Very low today, mostly grass pollen.
Last updated September 30, 2026
Pollen levels around Long Beach are quiet today. Tree pollen is absent entirely, while grass and weed pollen are both present but at very low levels. Most people, even those with sensitivities, should find the air easy to tolerate right now. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass and weed pollen staying low and tree pollen remaining out of the picture. This lines up with the season — local trees like ficus, ash, and the various palms (Washingtonia, Phoenix, and Arecastrum) are well past their spring release and won't become active again until next year. Grass tends to linger at low background levels through fall, and any weed pollen this time of year is typically mild as the season winds down.
