Twelve months of home care tuned to Indianapolis weather: what the snow, the thaw, the wet early summer, the humid peak and the dry fall each do to a house, and what to clean when.
Central Indiana has four real seasons, and each one dirties a house in its own way. The calendar below is built from the 1991 to 2020 climate normals for Indianapolis International Airport, the National Weather Service's tornado records and a few local schedules, so the timing matches what actually happens here.
Use it as a checklist for your own routine, or as a guide to when a deep clean or an extra visit pays off most.
Indianapolis averages 43.63 inches of precipitation and 25.5 inches of snow a year. January is the coldest month, with a normal average of 28.5 degrees and a normal low of 20.9, and also the snowiest, at 8.8 inches. June is the wettest month and July the warmest, with a normal high of 85.2 degrees and a dew point around 65. About 105 nights a year fall below freezing. Those few figures explain most of the cleaning year.
December averages 6.4 inches of snow, January is the peak at 8.8 inches, and February still brings about 6. The city also averages about 27 days a year with at least an inch of snow on the ground. Inside, that means one thing above all: salt and grit at every entry.
March averages 42.4 degrees and still brings about 3.2 inches of snow, but its 3.69 inches of total precipitation is far above February's 2.43. Melting snow, rain and leftover road salt combine into the muddiest stretch of the year for floors. This is the moment for the big reset: wash baseboards, clean window tracks that filled with grit over the winter, and wipe down blinds that have collected a winter's furnace dust.
Late March through April is also when most households open windows for the first time in months, which makes it a natural time to wash sills and screens. A One-Time Deep Clean booked in April clears what the whole winter left behind.
May and June are the two wettest months, at 4.75 and 4.95 inches. Yards stay soft, kids and dogs bring mud in, and garages and mudrooms need more frequent sweeping. Westfield residents can also use the city's spring Bulk Trash Day, held on the second Saturday of May at City Services on East 171st Street, to clear the garage before summer.
Severe weather belongs on the spring checklist too. The National Weather Service office in Indianapolis reports that Indiana averages 22 tornadoes a year, and it lists 47 tornadoes in Marion County between 1950 and 2025. Use a spring clean to clear and tidy the basement or interior room where your household would shelter, and keep a flashlight, water and sturdy shoes there so the space is ready the day a warning sounds.
The normal July dew point of about 65 degrees, and 63 in August, means the air carries a lot of moisture, and Indianapolis averages about 20 days a year at 90 degrees or above. Bathrooms stay damp, shower grout darkens faster and towels take longer to dry.
Run bathroom fans for a while after every shower, keep grout and caulk lines clean so mildew has less to feed on, and change or wash HVAC filters as the air conditioning runs hard. Kitchen grease also lingers with windows shut, so wipe range hoods and cabinet fronts more often.
Fall is drier and milder, and it is the best time for jobs that need open windows: washing screens, cleaning light fixtures and ceiling fans before they switch direction, and vacuuming upholstery. Westfield's fall Bulk Trash Day lands on the second Saturday of October, a good deadline for a garage or basement clear-out.
Before the first hard freeze, bring in hoses, wash the doormats and stock the entry with boot trays. With about 105 freezing nights to come, setting up the entry in November saves a lot of floor care later. Then book any pre-holiday deep clean before guests arrive.
