Low today, mostly tree pollen.
Last updated July 1, 2026
Grass pollen is the main player in Astoria today, sitting at a moderate level and driving the overall index to 3 (Moderate). Tree pollen has dropped to none, so the area's familiar Linden, Maple, Honeylocust, Liquidambar, and Prunus aren't contributing right now. The forecast holds grass steady at moderate for the next couple of days before easing to a lower level through the rest of the stretch. That fits the late-spring-into-summer pattern, when grasses take over after the spring tree season winds down. Ragweed and other weeds aren't a factor yet, as that activity typically arrives later in summer and into fall.
