Black locust
Robinia pseudoacacia
Very low today, mostly grass pollen.
Last updated September 30, 2026
Pollen is quiet across Torrance today. Tree pollen is absent altogether, while grass and weed are both present only at very low levels. Most people should be able to go about their outdoor plans without any irritation, and even those with sensitivities are unlikely to notice much of an effect. Looking ahead, this calm pattern should hold steady through the next several days, with grass and weed pollen staying low and tree pollen remaining a non-issue. This lines up with the season — local trees like pine, callistemon, and metrosideros are well past their spring pollen peak, and with autumn underway, weed pollen would typically be more of a concern than it is right now. For the time being, conditions remain mild and easy to manage.
