Detroit's allergy season is compressed but intense, running from April through October. The flat, agricultural landscape around Detroit, MI produces significant grass and ragweed pollen during peak months.
Right now: June is peak grass pollen in Detroit. Mowing season means freshly cut grass adds to airborne allergens.
Spring

Tree pollen season is short but intense — oak, elm, and ash dominate.
Summer
May – Jul
Grass pollen peaks in June. Agricultural regions see elevated counts.
Fall
Aug – Oct
Ragweed is the dominant allergen. The Midwest is a major ragweed zone.
The flat terrain near Detroit allows pollen to travel long distances on the wind. Cold fronts can temporarily drop counts, but warm spells bring rapid pollen surges. PollenTracker monitors these daily shifts.
