Very low today, mostly grass pollen.
Last updated July 9, 2026
Pollen levels in Carson are quiet today. Grass is the only type registering any activity, and even that is minimal, so most people should be able to go about their day without much irritation. Tree pollen is essentially absent right now, meaning oak, ash, pine, and other local trees are not contributing to the count. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass staying at a similarly low, barely noticeable level and tree pollen remaining out of the picture. This lull fits the season, as area trees like oak, ash, pine, ceratonia, and albizia typically finish their peak release earlier in the year, well before summer. Grass tends to linger longer, but current conditions suggest a mild stretch ahead for those who usually react to it.
