The following climate factors can influence how bad allergy symptoms might be:
• Tree, grass and ragweed pollens thrive on cool nights and warm days.
• Molds like heat and humidity.
• Pollen levels tend to peak in the morning hours.
• Rain washes pollen away, but their counts can soar after a rain.
• On a day with no wind, airborne allergens are grounded.
• When the day is windy and warm, pollen counts surge.
• Moving to another climate to avoid allergies is usually not successful – allergens are virtually everywhere.
