About pollen in Fairfield
Pollen levels around Fairfield remain quite low today. Both grass and weed pollen are barely registering, so most people should get through the day without any irritation. This is a calm stretch for allergy sufferers, with little in the air to trigger symptoms. Looking ahead, the next several days should bring more of the same, with grass and weed pollen staying at these low levels through the coming week. This lines up with the season, as summer's grass pollen has largely wound down and the typical late-summer rise in ragweed and other weeds has yet to make much of an impact locally. Tree pollen from species like oak and olive, common to the region, is also well past its spring peak, so overall conditions should stay easy on the sinuses for now.
