What makes it a good or a bad allergy season?

Generally speaking, a bad allergy season is one in which the amount of tree, grass, or weed pollen is greater
than normal or in the air longer than normal. Several factors can increase the quantity or duration of
pollination. An early spring (as we had this year) tends to accelerate pollination. A mild winter (as we had
this year) tends to encourage the trees to come on more strongly. So we have two elements for a bad season
this spring. Also a rainier season than normal (as we’ve had recently) encourages more vigorous plant
pollination and growth. So, we’ve had all three elements combining to make this year a “bad allergy season”
for people with pollen allergies driving their hay fever (allergic rhinitis) or bronchial asthma.
