Very low today, mostly weed pollen.
Last updated September 29, 2026
Pollen levels across Chinatown remain quiet today. Tree pollen is absent, and weed pollen is only barely present, so most people should be able to move through the day without any noticeable irritation. Overall, this is a low-impact day for allergy sufferers. Looking ahead, weed pollen is expected to tick up slightly over the next several days, settling into a low to moderate range that could be a bit more noticeable for those who are especially sensitive. This lines up with the seasonal pattern, as ragweed and other late-summer weeds tend to linger into early fall before fading. Tree pollen, meanwhile, should stay dormant, since local species like oak, elm, linden, and zelkova typically release their pollen in spring rather than this time of year.
