Gleditsia triacanthos
Moderate today, mostly tree pollen.
Last updated August 15, 2026
Tree pollen is the main contributor to today's moderate conditions in Fordham, with oak, honeylocust, plane, zelkova, and ash trees all contributing to the mix in the air. Weed pollen is present but at a lower, low level. Sensitive individuals may notice some effects today, though most people should get through the day without much trouble. Looking ahead, tree pollen is expected to ease over the next couple of days before ticking back up slightly by midweek, while weed pollen should hold steady at a low level throughout the stretch. This pattern is a bit unusual for mid-August, since tree pollen typically winds down well before now, giving way to weeds like ragweed as the dominant late-summer allergen. Keep in mind that late summer is also when grass and weed pollen tend to gain more of a foothold, so it's worth staying attentive as the season progresses.
