Douglas County pollen, Eppley weatherAllergy season in Omaha: pollen counts, humidity and the bed
Omaha's pollen year starts with trees in March, per UNMC, and DCHD was still counting weeds on October 2, 2026. Three public counts track it: the Douglas County Health Department's numbers in the National Weather Service bulletin, UNMC's twice-weekly counts, and NAB Station 33 in Bellevue. These guides pair those counts with NOAA's Eppley Airfield normals and say where a mattress cleaning fits, and where it doesn't.
When is allergy season in Omaha?
| Month | Pollen timing and source | Eppley dew point | Eppley wind | Also worth knowing |
|---|---|---|---|---|
| March | Trees begin pollinating (UNMC, 2014) | 28°F | 11.3 mph | |
| April | Trees in full swing by early to mid-April (UNMC, 2014) | 38°F | 11.8 mph | Windiest month; NOAA's median last 32°F night at Eppley is April 18 |
| May | Grass may begin (UNMC, 2014) | 50°F | 10.5 mph | UNMC called May 2022 near the tree and grass peak |
| June | Grass, under UNMC's May-or-June start | 61°F | 9.7 mph | |
| July | No new pollen type in UNMC's timeline | 66°F | 8.5 mph | Highest dew point |
| August | Ragweed around August 15 (UNMC, 2014) | 64°F | 8.2 mph | Calmest month |
| September | DCHD weeds 54, high, on September 28, 2026 | 55°F | 9.2 mph | Ragweed named in the DCHD count that day |
| October | DCHD weeds 12, moderate, on October 2, 2026 | 41°F | 9.8 mph | NOAA's median first 32°F night at Eppley is October 21 |
Pollen timing for March to August is from UNMC allergist Jill Poole (March 2014) and UNMC's May 2022 release; UNMC's timeline stops at ragweed in August, so September and October use DCHD's counts. Dew point and wind are our monthly averages of NOAA's 1991 to 2020 hourly normals for Eppley Airfield; freeze dates are NOAA's medians. The September and October counts are the Douglas County Health Department's, as printed in the NWS Omaha/Valley bulletin.

Who counts Omaha's pollen?
The Douglas County Health Department supplies the daily counts and air quality forecast that the National Weather Service in Valley publishes as the Omaha Pollution Index/Pollen Count. UNMC's Division of Allergy and Immunology has run a seven-day sampler on the roof of Durham Research Center II since late 2020 and posts on Tuesdays and Thursdays in peak season. The National Allergy Bureau lists The Asthma & Allergy Center's rooftop at Bellevue Medical Center as Station 33. Our pollen count guide lays DCHD's five bulletins from September 28 to October 2, 2026 side by side.
When should you book a visit during allergy season?
Weekday visits (Monday to Friday, 9am to 6pm) open with an inspection form noting material, special care notes and any urine or odor observations; our technicians work in gloves and shoe booties, disinfect equipment between jobs, and finish with two checks only, a moisture check after the job and the dust mite (bed mite) sensor on our UV-C vacuum. A 72-hour bedroom CO₂ test is a separate optional service, booked on its own or added to a visit and priced by quote; it isn't a medical test. Pricing: $249 for the first mattress, $199 per additional full, queen or king and $149 per additional kids bed, with normal stains, pet odor and ordinary urine accidents included and a surcharge only for severe or biohazard cases, quoted before we start; check your care label and warranty terms before booking.
We make no allergy, asthma or other health claim for a mattress cleaning; this page is general information, not medical advice.
How heat affects bed mites (house dust mites), and why killing them isn't the same as removing them, is covered once for every city in the Sleep Sanitation Knowledge Center.
What don't we know yet?
- Where DCHD's sampler sits, since the NWS bulletin doesn't say.
- The units behind DCHD's numbers, which the NWS bulletin labels low, moderate or high without stating grains per cubic meter.
- When UNMC will post its first 2027 counts, since its page says only "during peak season."
