Black locust
Robinia pseudoacacia
Very low today, mostly grass pollen.
Last updated July 21, 2026
Pollen levels in Torrance are quiet today. Tree pollen is absent, and grass pollen is running very low, so most people should be able to go about their day without much irritation. Overall, this is a mild day for allergy sufferers. Looking ahead, conditions are expected to stay largely the same over the next several days, with grass pollen holding at a low, steady level and tree pollen remaining minimal. This fits the seasonal pattern for midsummer, as trees like Pyrus, Ginkgo, Prunus, Cupaniopsis, and Macadamia typically release most of their pollen in spring and are now well past their peak. Grass pollen tends to linger at low levels through this time of year, so only slight, occasional sensitivity is likely for those who are especially prone to it.
