Low today, mostly weed pollen.
Last updated September 29, 2026
Weed pollen is the most active category in Mid-City today, though it remains at a low level overall. Tree and grass pollen are both very low, so most people should notice little to nothing from those sources. For anyone particularly sensitive to weeds, there may be mild awareness of symptoms, but conditions overall are calm. Looking ahead, tree pollen is expected to fade further over the next few days, essentially disappearing from the count, which fits the season since local trees like plane, tristania, maple, ficus, and oak typically finish their release well before fall. Grass is expected to hold steady at a very low level throughout the period. Weed pollen may ease slightly before ticking back up toward the end of the stretch, consistent with this time of year, when ragweed and related weeds are typically the main source of autumn allergy activity.
