Low today, mostly tree pollen.
Last updated July 1, 2026
Pollen levels across Chinatown are running low today, with an overall Universal Pollen Index of 1 (Very Low). Grass is the main contributor at a Very Low reading of 1, while tree pollen has dropped to none, leaving local species like Eucalyptus, Prunus, Magnolia, Olea, and Ficus quiet for now. The five-day grass forecast holds steady at 1 throughout, so expect more of the same modest conditions in the days ahead. This pattern fits the late-spring-into-summer stretch, when tree pollen has tapered off from its spring peak and grass becomes the more typical driver. Overall, it's an easy spell with little change anticipated in the near term.
