The Worst and Best Months in Millsboro
Millsboro'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.
Delaware has an early spring tree season and a strong 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 Delaware can help with testing and longer-term options like allergy shots.
