About pollen in Rockford
Pollen levels in Rockford are quite low today, with both tree and weed sources barely registering. Grass isn't showing any activity worth noting either. For most people, today should feel like an easy day outdoors, with little to no irritation expected even for those who are usually sensitive. Looking ahead, weed pollen is expected to tick upward over the next several days, reaching a more noticeable level by the end of the forecast window, while tree pollen stays mild throughout. This pattern fits the season — mid-August marks the start of ragweed's gradual rise, which tends to be the dominant player through early fall. Tree pollen from sources like oak, maple, and elm is largely finished for the year, so any tree-related symptoms should stay minimal in the coming days.
