Monterey pine
Pinus radiata
Very low today, mostly weed pollen.
Last updated August 15, 2026
Pollen levels in Chinatown remain quiet today. Tree pollen is essentially absent, while weeds are registering only a very low presence. For most people, this means little to no irritation, though those with particular sensitivity to weed pollen may notice a mild effect. Looking ahead, this calm pattern is expected to hold steady over the next several days, with tree pollen staying near zero and weeds continuing at a low, steady level. This fits the seasonal picture for mid-August, well past the spring bloom of trees like Prunus, Magnolia, Olea, Ficus, and Pittosporum, and ahead of the more active late-summer weed season. For now, conditions remain favorable for spending time outdoors with little concern about pollen exposure.
