Source: The National Allergy Bureau™Trees, grasses, weeds and ragweed generally bloom at the same time each year. This means that the onset and end of pollen seasons throughout the country are relatively standardized from year to year.
This page has been created so allergy sufferers can know when pollen seasons occur, schedule outdoor activities when pollen is at lower levels and ultimately better manage their allergy symptoms.
