About pollen in Nashua

Pollen levels in Nashua are running low today, with both tree and weed sources holding fairly steady. Neither is contributing much in the way of noticeable symptoms, so most people should find conditions comfortable to be outside. If you tend to be sensitive to weed pollen, you might catch a faint trace of it, but overall this is a mild day for allergies. Looking ahead, the next several days should stay similarly quiet, with a slight dip expected midweek before levels tick back up to their current low range. This time of year, tree pollen from species like oak and birch has largely wound down, and the season is shifting toward weeds, particularly ragweed, which tends to build through late summer and into fall. For now, though, there's little cause for concern, and conditions look set to remain manageable through the coming days.
