About pollen in New Haven
Pollen activity in New Haven is minimal today, consistent with mid-November conditions. With trees bare and grasses long dormant, there is little airborne pollen to speak of, so most residents, including those with seasonal sensitivities, should find today comfortable on that front. Looking ahead, this quiet pattern should hold through the next few days, as the region is well past the growing season for the trees, grasses, and weeds that typically drive allergy symptoms. New Haven's familiar culprits, like oak, maple, and birch in spring, along with grasses in early summer and ragweed into early fall, are all out of season now. Any lingering outdoor irritation this time of year is more likely tied to mold spores from damp leaf litter than to pollen itself.
