Low today, mostly weed pollen.
Last updated August 14, 2026
Weed pollen is the main story in Jersey City today, though it remains at a low level overall. Tree pollen is barely present at this point, so most sensitive individuals shouldn't notice much from that source. Between the two, weed is the one worth keeping a light eye on, but conditions overall are mild and unlikely to cause significant trouble for most people. Looking ahead, tree pollen is expected to stay minimal through the next several days, which lines up with the season — trees like oak, zelkova, honeylocust, ginkgo, and linden finished their heavier pollen release back in spring and are quiet now. Weed pollen will likely hover in the low range as well, with a slight uptick possible toward the end of the stretch. This pattern is typical for mid-August, as we edge closer to the period when ragweed and other late-summer weeds tend to become more active.
