What to clean and when, based on Omaha's real freeze dates, snowiest months and summer dew points, along with the bugs and storms that come with each part of the year.
Omaha gets a true four-season year, so a seasonal plan is actually useful here. These are not arbitrary dates. They follow the normals at Eppley Airfield and what County Extension says about insects.
Use the order as a guide. Weather moves around from year to year, and your household matters more than the calendar. A home with dogs and a mudroom will hit these jobs sooner.
Omaha has a hot-summer humid continental climate. Median freeze dates are April 18 in spring and October 21 in fall, with about 135 nights a year at or below freezing. Snow averages 27.1 inches, with 7.8 inches in February and 7.2 in January.
Precipitation is 31.86 inches a year, led by May at 4.66 and August at 4.60. The July normal high is 88.1 degrees, with about 33 days at 90 degrees or hotter. Dew points reach about 66 degrees in July and fall to about 16 degrees in January.
The January normal high is 33.6 degrees and the low is 15.2. Windows stay shut and the furnace runs. Wipe registers and vents, wash down the hard floors at each door and dust ceiling fans that may not have run in months. Keep boot trays emptied, because melted grit dries into a fine powder that spreads over the house. February is the snowiest month, so do not put away the entry mats.
Spring storms can still be serious. The March 19, 2025 blizzard brought a 63 mph gust to Eppley Airfield with rain turning to sleet and heavy, wet snow, so do not rush the winter gear away. After the median last freeze of April 18, it is time to wash windows, wipe sills and tracks and shake out mats.
A One-Time Deep Clean fits well here, since it clears a season of furnace dust from blinds, vents and baseboards.
May has the highest normal rainfall and it brings mud with it. Keep entries washed and check the basement for damp corners. Tornado history matters here: the May 6, 1975 tornado destroyed 287 homes along 84th Street. The Weather Service also lists a May 24, 2024 derecho in its recent events, so a basement that is clear enough to shelter in is the most useful spring project you can do.
With dew points near 66 degrees in July, bathrooms dry slowly. Run the fan and keep shower glass squeegeed. Kitchens draw insects in the warm months, so take scraps out daily. August is the second-wettest month, so mud returns. The July 31, 2024 wind event shows that heavy storms do not stop in spring, so be ready to wipe up after open windows catch a sudden blast of rain.
The median first freeze is October 21. Before that, wash curtains, vacuum window tracks and dust the high shelves you will not reach once the holidays begin. Extension notes that lady beetles and boxelder bugs look for warm places to overwinter, and that lady beetle fluid can stain. Vacuum them up rather than crushing them.
Papillion and La Vista residents can also clear out furniture and major appliances at the two cities' shared fall cleanup event.
Set out boot trays before the first snow. Clean the oven before the holidays, or set aside time for it, as a regular visit does not go inside it. Go through closets and storage while you still have mild days. If you are clearing out old paint or cleaners, take them to UnderTheSink rather than storing them over another winter. Unusual events happen late in the year as well: on December 15, 2021, strong winds carried dust from Kansas into the area, along with the smell of smoke from grass fires.
