Black locust
Robinia pseudoacacia
Very low today, mostly weed pollen.
Last updated August 15, 2026
Pollen levels in Torrance are quiet today. Tree pollen is essentially absent, and weeds are registering only a very low presence. For most people, this should mean little to no irritation, even for those who are typically sensitive to seasonal pollen. Looking ahead, this calm pattern is expected to hold steady over the next several days, with weed pollen staying at a low, consistent level and tree pollen remaining a non-issue. This lull fits the season, since local trees such as Pyrus, Ginkgo, Prunus, Cupaniopsis, and Macadamia typically release their pollen in spring and are dormant this time of year. With grass season winding down and ragweed and other late-summer weeds only beginning to stir, outdoor conditions should stay comfortable for the near future.
