The Worst and Best Months in Wellfleet

Wellfleet'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.

Massachusetts has a spring tree season and a strong ragweed season in late summer and early 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 Massachusetts can help with testing and longer-term options like allergy shots.
