About pollen in New Haven

Pollen levels in New Haven are low today, with tree and weed pollen running about even. Most people should get through the day without much irritation, though those with sharper sensitivities may notice a mild effect from weed pollen in particular. Looking ahead, conditions are expected to stay in the low range through the next several days, with only slight day-to-day shifts. This tracks with the season: tree pollen from oaks, maples, and birches is well past its spring peak and now contributing little, while weed pollen — including early ragweed — is just beginning its typical rise heading into late summer and fall. For now, the overall outlook remains calm and manageable.
