Low today, mostly tree pollen.
Last updated July 10, 2026
Pollen levels across the Upper West Side are running low today. Tree pollen is present at a mild level, with contributions from trees like oak, elm, plane, honeylocust, and ginkgo, while grass pollen is barely registering. Most people should find the air comfortable, with little to prompt symptoms even among those who tend to be sensitive. Looking ahead, expect conditions to stay fairly quiet over the next few days, with grass pollen ticking up slightly toward the end of the stretch. This lines up with the seasonal pattern — tree pollen has largely wound down after its spring peak, and grasses tend to linger into early summer before giving way to ragweed later in the season. For now, there is little reason to expect any significant change in how the air feels.
