About pollen in New Haven
Grass pollen is the main driver in New Haven today, sitting at a moderate level (3) and pushing the overall index to moderate as well. Tree pollen has dropped to very low (1), which fits the seasonal pattern now that the spring peak from oaks, birches, and maples is well behind us. The forecast shows grass easing slightly to the low-moderate range over the next couple of days before nudging back up toward moderate, so expect more of the same fluctuation rather than any sharp change. Late June is squarely in grass season, which typically runs through late spring and early summer here. Weed pollen is not being reported in the current data, and ragweed generally doesn't become a factor until late summer.
