About pollen in Hartford
Pollen levels in Hartford are low today, with tree and weed sources both contributing modestly to the overall count. Neither is likely to cause much trouble, though those with heightened sensitivity may notice mild effects when spending extended time outdoors. Looking ahead, conditions should remain fairly steady over the next several days, with a slight dip midweek before returning to today's level. This is a quieter stretch for tree pollen, as the oaks, maples, and birches that dominate the region's spring season have long since finished releasing their pollen. With mid-August underway, weed pollen—particularly ragweed—is beginning its gradual climb toward the more active late-summer and early-fall period, so it is worth keeping an eye on how levels shift in the coming weeks.
