Very low today, mostly grass pollen.
Last updated October 15, 2026
Pollen levels across Carson are quiet today. Tree pollen is absent entirely, while grass and weed pollen are both present only in very small amounts. Most people, even those with sensitivities, should get through the day without much irritation. Looking ahead, little change is expected over the next few days. Grass and weed pollen are likely to stay at these very low levels, and tree pollen should remain negligible for now. This fits the season — local trees such as oak, ash, pine, ceratonia, and albizia typically release their heaviest pollen in spring, so their quiet stretch through mid-October is expected. Weed pollen, which tends to linger into fall, is also behaving mildly this week, making for an easy stretch for allergy sufferers overall.
