Low today, mostly weed pollen.
Last updated August 14, 2026
Weed pollen is the most active type in Chinatown today, though it remains at a low level that most people should be able to tolerate without much trouble. Tree pollen is running very low, so it's not a significant factor right now. Overall, this is a fairly easy day for allergy sufferers, with only mild potential for irritation among those especially sensitive to weeds. Looking ahead, tree pollen is expected to stay minimal through the next several days, offering little concern for those affected by species like elm, oak, linden, and zelkova, which are well past their active season. Weed pollen should hold in the low range as well, with a slight uptick possible later in the stretch. This pattern fits the time of year, as late summer typically sees quieter tree activity while weed pollen, including early ragweed, begins its gradual climb toward the more prominent fall season.
