Monterey pine
Pinus radiata
Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels in Chinatown are quiet today. Tree pollen is absent, and grass pollen is only present at a very low level, so most people should be able to go about their day without any noticeable irritation. Even those with heightened sensitivity are unlikely to feel much effect under these conditions. Looking ahead, this calm pattern is expected to hold, with grass staying at a very low level over the next couple of days and tree pollen remaining absent. This lull fits the season — local trees such as Prunus, Magnolia, Olea, Ficus, and Pittosporum typically release their pollen in spring, so their contribution is minimal by midsummer, while grass pollen, though present, is not showing any signs of a significant rise right now. Overall, it looks like a mild stretch for allergy sufferers in the near term.
