About pollen in New Haven
Pollen activity in New Haven is minimal today. Weeds are the only category registering, and even that presence is very low, so most people should be able to go about outdoor plans without much concern. Sensitive individuals may notice a faint trace, but for the majority this is a quiet day for allergies. Looking ahead, weed pollen is expected to hold steady at this low level for the next couple of days before ticking up slightly toward the end of the five-day outlook. This lines up with the season, since ragweed and other late-season weeds typically linger into early fall before tapering off. Tree pollen from species like oak and maple is long finished for the year and won't return until spring, so weeds remain the main thing to keep an eye on through this stretch of autumn.
