Acer rubrum
No notable pollen right now.
Last updated November 12, 2026
Pollen activity in Warren is essentially at a standstill today. Tree pollen, the only type being measured right now, is reading at none, which means the air is clear on that front. Anyone who typically reacts to tree pollen should have an easy day with little to no irritation from this source. Looking ahead, conditions are expected to stay quiet, with tree pollen holding at this same low level through the coming days. This lull fits the season well: mid-November is far removed from the spring months when trees like maple, oak, linden, and crabapple release the bulk of their pollen, so a period of calm is typical this time of year. For now, there is little reason to expect any meaningful change in the near term.
