Allergy Season

How does Weather Affect Allergies?

Weather plays a direct role in the severity and length of the allergy season. Weather conditions will increase the amount of pollen production to yield high pollen levels or decrease pollen production to yield low pollen levels.

A mild winter can signify an early allergy season, since trees tend to start pollinating earlier.

Dry, windy weather spreads pollen quickly, producing a higher distribution of pollen…increasing allergy symptoms.

A late freeze can delay tree pollination, producing lower pollen counts.

Rain can reduce the pollen count by washing pollen from the air, thereby providing relief for allergy sufferers. Although sometimes rain can cause an adverse effect: rain in late fall or winter can increase tree pollination amounts, causing higher pollen levels. Increased rain in spring makes grass grow faster to produce more unwanted pollen.

An Allergy Forecast for Every Allergy Season

To determine an accurate allergy forecast, weather is analyzed, including winter weather conditions, freeze dates, and rain conditions. Current pollen data also helps determine an allergy forecast.
