About pollen in Fairfield
Pollen levels in Fairfield are quiet today, with weeds registering as the only active category and barely so. Anyone sensitive to ragweed or similar late-season weeds should notice little to no effect, and most residents can expect a comfortable day outdoors without much concern about airborne irritants. Looking ahead, the next several days should bring more of the same, with weed pollen holding steady at a low level throughout the stretch. This lull fits the season: oak, ash, and other regional trees finished releasing pollen months ago, and grasses have largely wound down as well. Weed pollen, including ragweed, typically builds through late summer into fall, so while today's numbers are mild, it's worth keeping an eye on conditions as the season progresses toward its usual peak.
