A month by month list for Spokane homes, built around snow from December on, tree and grass pollen in spring, a bone dry July and August, and a smoke season that can run into fall.
Spokane's weather sets a clear rhythm for keeping a house. Its normal January low is 24.7 degrees, its normal July high is 84.4, and annual precipitation is 16.45 inches. Here is a month by month list to use as a guide. Move things around as the weather and your household demand.
Normal annual snowfall at Spokane International Airport is 45.4 inches, with 13.8 in December and 12.3 in January, and about 48 days a year have at least an inch on the ground. July and August are the driest months, at 0.42 and 0.47 inches, and December is the wettest at 2.34.
Tree pollen starts as the ground warms in late winter and spring, grasses come in late spring and summer, and weeds run from late summer until the first hard freeze. Wood burning restrictions come most often in fall and winter.
January. Normal snowfall of 12.3 inches keeps grit coming through the door. Wash entry mats often, wipe up slush before it dries, and change furnace filters. Check for wood burning restrictions before you light a fire.
February. A good month for indoor jobs like closets and basement shelves. Dust screens and electronics, and vacuum vent covers. Keep walkways clear for anyone coming to your door.
March. Tree pollen can begin as the ground warms. Wash the winter off entry floors and baseboards, and set out a boot tray for the mud that comes with the thaw.
April. Tree pollen gets going. Keep windows shut on heavy days, and wipe sills with a damp cloth. Manito Park's gardens, established in April 1904, are a nice reminder of what the pollen is for, even when your nose disagrees.
May. A good month for a One-Time Deep Clean, once the heating season is finished. Baseboards, tracks and vents have a full winter's dust in them. Test bathroom fans and clean the covers.
June. Grass pollen is the main concern. Wash bedding and curtains more often, and change your air conditioner filter before it gets hot.
July. The normal high is 84.4 degrees, with a normal low of 57.6, and about 21 days a year reach 90 or above. Air out the house in the cool of the morning. Dust settles fast, so use a damp cloth.
August. Normal precipitation is just 0.47 inches. The Spokane Area Fires of August 2026 burned 10,363 acres and damaged or destroyed an estimated 846 structures, so keep important papers, photos of each room and a go-bag in order. Clear debris from around the house.
September. Smoke can linger. During smoke events, keep windows closed and avoid vacuuming and dusting unless your vacuum has a HEPA filter. Once the air clears, wipe down blinds, fans and sills. Weed pollen continues until the first hard freeze.
October. Have the furnace serviced, and clean vent covers before heating season. Store outdoor cushions, and sort out the garage while it is still comfortable to work in. Wood burning restrictions become more common from here on.
November. A good month for a deep clean before holiday cooking. Clean oven racks and the range hood, and check that guest rooms are in order. Set up mats and a boot tray before the first big snow.
December. The snowiest month, at a normal 13.8 inches, and the wettest, at 2.34 inches, with a normal high of 33.8 degrees. A Recurring House Clean can keep the regular work going while you handle the holidays. If your lease is ending, read the move-out guide ahead of time.
