The Worst and Best Months in Union City

Union City's pollen usually peaks in September, driven by Ragweed. If your allergies flare on the same weeks every year, that is usually why. The calmest month is typically January.

Pennsylvania has a spring tree season, grass in early summer, and a heavy ragweed season in the fall.

A pollen calendar shows the usual pattern, but weather shifts it. A warm winter pulls tree season earlier, and a late frost stretches ragweed into November. Start any allergy medication a week or two before your worst month, and check the daily count to catch the spikes. If symptoms hit hard every season, an allergist in Pennsylvania can help with testing and longer-term options like allergy shots.
