About pollen in Jacksonville
Weed pollen is the main story in Jacksonville today, running high and likely to be noticeable for anyone who deals with seasonal sensitivities. Grass pollen adds to the mix at a moderate level, while tree pollen remains low and should be easy to overlook for most people. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen staying elevated, grass holding at a moderate level, and tree pollen continuing to be a minor factor. This lines up with what's typical for late September into fall in the region, as ragweed and other weeds move into their most active stretch while oak, pine, and other local trees stay quiet until their heavier pollen season returns in spring.
