Very low today, mostly grass pollen.
Last updated July 8, 2026
Pollen levels in Hawthorne are quiet today. Grass pollen is present but only at a very low level, while tree pollen is absent entirely. Most people should have no trouble at all, and even those with sensitivities are unlikely to notice much in the way of symptoms. Looking ahead, this calm pattern is expected to hold over the next several days, with grass staying at a similarly low, easygoing level. Tree pollen from local species such as Pittosporum, Ceratonia, Schinus, Cupaniopsis, and Elm typically peaks earlier in the spring, so it makes sense that trees are not contributing much right now. With summer underway, grass remains the main source of pollen in the area, and conditions this week look like a mild stretch overall.
