Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels around Chinatown are quiet today. Tree pollen is absent entirely, while grass pollen is registering only a very low presence. For most people, this means little to no irritation, though those who are especially sensitive to grass might notice a mild effect if spending extended time outdoors. Looking ahead, conditions are expected to hold steady over the next few days, with grass pollen remaining light and tree pollen staying inactive. This tracks with the season: local trees such as oak, honeylocust, ginkgo, styphnolobium, and elm typically finish their pollen release well before midsummer, so their dormancy now is expected. Grass pollen can linger into early summer before tapering off, which fits the low levels being seen currently. Overall, it's a calm stretch for allergy sufferers in the city.
