Last updated July 20, 2026
Pollen levels in Warren are quiet today, with tree pollen sitting at essentially none. Anyone sensitive to allergens should get a bit of a break, as there is little in the air right now to trigger the usual sneezing or itchy eyes. Looking ahead, tree pollen is expected to remain minimal over the next stretch of days, which lines up with the season. The spring push from trees like maple, oak, and linden has long since passed, and the varieties common to the area, including malus and gymnocladus, are well past their peak release. For now, conditions look calm, though it is worth keeping an eye on grass and weed pollen as summer continues.
