Low today, mostly weed pollen.
Last updated September 30, 2026
Weed pollen is the only real presence in Jersey City's air today, and it's sitting at a low level. Most people will get through the day without much trouble, though those with a strong sensitivity to ragweed and similar late-season weeds may notice mild effects. Tree pollen is absent right now, so overall conditions are quiet. Looking ahead, weed pollen is expected to hover in the low range over the next several days, drifting up and down slightly but staying manageable. This lines up with the season: early fall is typically ragweed's stretch, while tree pollen from species like oak, linden, and honeylocust has long since wound down after its spring peak and isn't expected to return in any meaningful way until next year. For now, weeds remain the main thing worth keeping an eye on.
