Very High Tree Pollen Levels Continue – Third highest Tree Pollen levels in 2026
Highest Levels of Tree Pollen Detected in the United States for 2/27/2026
February 27, 2026
A VERY HIGH ALERT has been issued for tree pollen levels in Oklahoma City, marking the SEVENTH VERY HIGH ALERT in the last eleven days, and the EIGHT HIGH or VERY HIGH ALERT in that same timeframe. Today’s counts are the highest reported in the U.S. and the third highest recorded this year.
This marks the FIFTH day this year in the TOP TEN days for Cedar Season (in the past five years), and TENTH highest day for Tree Pollen (All Seasons) in twenty years.
Cedar Fever and Regional Impact
Cedar tree pollen contributes to “Cedar Fever”, a winter allergy affecting millions across Oklahoma, Texas, Arkansas, and Missouri. Unlike spring and summer allergies, Cedar Fever peaks from late November to February, with pollen grains capable of traveling hundreds of miles in Oklahoma winds.
Recommendations to Reduce Exposure
OAAC allergists recommend the following steps:
- Limit outdoor activities on high pollen days
- Keep windows closed at home and in vehicles
- Change clothes and shower after being outdoors
- Leave shoes at the door to avoid tracking pollen inside
- Wash hands frequently, especially after outdoor contact
- Wear a dust mask for outdoor chores
- Use and regularly replace HEPA filters in HVAC systems
Medical Management
- Continuous use of nasal sprays and antihistamines may help, but proper diagnosis is essential
- Seasonal allergies cannot be diagnosed by history alone. OAAC allergists offer simple tests to identify specific triggers
OAAC serves patients of all ages across the southwest region, with clinics in Edmond, Norman, northwest Oklahoma City, and the OU Health Sciences Center campus.
