About pollen in Waterbury

Pollen levels in Waterbury are on the mild side today, with both tree and weed sources registering low. Neither is likely to cause much trouble for most people, though those with stronger sensitivities may still notice a mild effect, particularly from weed pollen drifting through the warm August air. Looking ahead, tree pollen should ease slightly over the next few days, which fits the season, since the oaks, maples, and birches typical of the region finished their heavy pollen production back in spring. Weed pollen is expected to hold fairly steady at a low to occasionally moderate level, a pattern common in mid-August as ragweed and other late-summer weeds begin their gradual rise toward the more active fall stretch. Overall, conditions look calm and manageable through the week.
