Very low today, mostly weed pollen.
Last updated October 9, 2026
Pollen levels in Detroit are quiet today. Tree pollen is absent, and weed pollen is running very low, making it unlikely that most people will notice any effects even if they are typically sensitive to it. Looking ahead, this calm pattern should hold over the next few days, with weed pollen staying at a low level and tree pollen remaining out of the picture. This fits the season, as trees like oak, maple, and elm finished releasing their pollen months ago and won't become active again until spring. Any lingering weed pollen this time of year is a normal tail end of the fall allergy season, and it continues to fade as the weather cools.
