Low today, mostly weed pollen.
Last updated September 29, 2026
Weed pollen is the only real presence in Fordham today, and it remains at a low level, which most people will not notice unless they are especially sensitive to it. Tree pollen is absent entirely, so overall conditions are mild and easy to manage for the vast majority of residents. Looking ahead, weed pollen is expected to tick upward over the next several days, moving from a low reading into a moderate range by midweek. This lines up with the typical late-September pattern, as ragweed and related weeds continue their seasonal run into fall. Tree pollen from species like elm, oak, and ash should stay quiet for now, since these trees are well past their spring release and won't factor in again until next year.
