Monterey pine
Pinus radiata
Very low today, mostly grass pollen.
Last updated September 29, 2026
Pollen levels in Chinatown are quite low today. Tree pollen is absent, while both grass and weed pollen are present only at very low levels. Most people should find the air comfortable, with little chance of noticeable irritation even for those who tend to be sensitive. Looking ahead, this calm pattern is expected to hold through the next several days, with grass and weed pollen staying at similarly low levels and tree pollen remaining quiet. This fits the season well: local trees such as Prunus, Magnolia, Olea, Ficus, and Pittosporum typically release their pollen in spring, so their dormancy now is expected, and any lingering grass or weed presence is a normal tail end of the late-summer and early-fall pattern rather than a sign of rising activity.
