US climate is also an allergy calendar. Moving from a short northern spring to Atlanta or Austin can feel like a new medical season: Southeast climate.
How do seasons and regions differ?
Tree pollen leads early spring in many metros. Grass follows. Ragweed dominates late summer into fall across large parts of the East and Midwest, including Chicago: Midwest climate. Longer frost-free seasons in the South stretch exposure.
Humidity and mold can stack on pollen misery: Humidity. Smoke and urban pollution are separate but related air stressors: Air quality.
What helps movers day to day?
Track local pollen counts, shower after heavy outdoor days, keep windows closed on peak afternoons, and consider a HEPA purifier for bedrooms. Do not judge a city by a midwinter scouting trip if spring is your hard season.
Common misconceptions
Assuming desert cities have zero allergy load fails spring blooms and some ornamental plantings.
Assuming one antihistamine routine transfers unchanged across climates also fails when seasons lengthen.
Summary
Read pollen as a relocation factor. Match your worst season to regional calendars before you celebrate a city’s average temperature score.
