What to clean and when in a Tulsa home, built around the late March freeze, the May rain peak, 74 days of 90 degree heat and the winter ice that sometimes follows.
The calendar on a Tulsa fridge and the calendar for its cleaning do not quite match. Spring comes with hail. Summer runs long and sticky. Fall is brief but comfortable, and winter is mild until, once in a while, it is not. Dividing chores by what the weather is doing works better than the old idea of one big spring clean.
Everything below comes from NOAA normals for Tulsa International Airport and from the National Weather Service office in Tulsa. Use it as a checklist you can do yourself, or as a guide to timing a professional visit.
January's normal low is 28 degrees, and Tulsa averages about 72 nights a year at or below freezing. With the house shut up, this is the time for inside jobs that get skipped all year: wipe the tops of door frames, pull out the sofa, clean under beds and check the furnace filter.
Snow averages 8.7 inches a year, most of it from December through March. When it falls, put a tray by the door so melt does not sit on wood. Keep a flashlight, batteries and a cooler where you can find them. The ice storm of December 9 and 10, 2007 left more than 200,000 homes in northeast Oklahoma without power for several days, and a tidy freezer makes an outage easier to get through.
The last 32 degree freeze typically comes in late March, and the growing season starts in earnest. Tulsa's place near the top of the 2026 Allergy Capitals report is a good reason to deal with pollen as a chore in its own right. Wash the blinds, wipe window sills and tracks, and launder the curtains. Change your air filter when the first yellow film appears on the car.
April brings the start of the hail peak, which the Weather Service gives as mid April to mid May. A hail storm rattles leaves, twigs and shingle grit onto porches, and all of it wants to come inside. Sweep the porch and shake the mats after each one.
May is the wettest month at 5.73 inches, and the National Weather Service calls spring the wettest season. Expect wet boots and paw prints, and put the mop near the back door. Check under sinks and around the water heater after hard rain. The Tulsa Health Department says most household mold can be cleaned once the moisture source is fixed, so find the leak first.
June is when the heat begins to build. Run bathroom fans longer now, and wipe down shower walls as the air gets heavier. Moist Gulf air and southerly winds are normal here through most of the year, and bathrooms dry more slowly than you may expect.
Tulsa averages about 74 days at 90 degrees or hotter and 10.8 days at 100 or hotter, with a normal July high of 93.6. The air conditioning does most of the work now, so vacuum vents, change the filter on schedule and wipe the ceiling fan blades before they fling dust around the room.
Keep the back door routine going. The Tulsa Health Department traps mosquitoes through spring and summer and asks residents to dump standing water, so empty saucers and birdbaths while you are out. Late summer is also a good time for a cleaning of the refrigerator seals and pantry shelves, because heat makes spills and crumbs matter more.
The first freeze usually comes in early November, and the growing season winds down after that. This is the best time of year for a second round of deep work. Baseboards, window tracks and fan blades have carried the whole summer by then, and the holidays are coming. Book a One-Time Deep Clean here if you want a reset before guests arrive.
December brings the first real chance of winter weather. Pull out the entry mats again and check that your storm supplies are where you left them. The storm season guide has more on getting ready and on what to do after ice or hail.
