Red maple
Acer rubrum
No notable pollen right now.
Last updated November 14, 2026
Pollen activity in Baltimore is essentially quiet today. Tree pollen, the only category being measured right now, sits at zero, meaning sensitive noses should get a break from symptoms tied to airborne pollen. Looking ahead, conditions are expected to stay calm over the next few days, with no meaningful tree pollen in the forecast. This lull fits the season, as mid-November falls well after the main pollen period for local trees like oak, ginkgo, magnolia, lagerstroemia, and cotinus, which typically release their pollen in spring. Grass and ragweed season have also wound down for the year, so allergy sufferers can expect a relatively comfortable stretch before tree pollen returns in the spring.
