Very low today, mostly tree pollen.
Last updated August 15, 2026
Pollen levels in Astoria are quiet today, with both tree and weed sources sitting at a very low level. Neither is likely to cause much trouble for most people, and even those with sensitivities should notice little in the way of symptoms. It is a calm day overall for anyone who typically reacts to airborne pollen. Looking ahead, conditions are expected to stay largely the same through the rest of the week, with weed pollen ticking up slightly to a mild, noticeable level for a single day before settling back down. Tree pollen from local species such as maple, honeylocust, liquidambar, prunus, and pyrus is essentially finished for the season at this point, since these trees release most of their pollen in spring. Mid-August is when weed pollen, including early ragweed, typically starts to become more of a factor, so it is worth keeping an eye on as late summer progresses.
