A month by month cleaning plan for Raleigh-Durham homes, drawn from airport climate normals, the state pollen sampler, NC State Extension pest notes and the area's storm history.
Generic spring cleaning lists assume a cold winter and a gentle spring. Raleigh has neither in quite that form. The winter is short, the pollen peak is intense, the summer is long and sticky, and fall brings rain and bugs before the leaves even finish. This calendar follows the Raleigh-Durham year as the airport records it, so each month's chores match what is actually happening outside.
NOAA's 1991 to 2020 normals for Raleigh Durham International Airport show 46.07 inches of rain in a typical year, spread over about 75 days with at least a tenth of an inch. The airport averages 64.7 nights at or below freezing and 52.4 days at 90 degrees or warmer. Snow is light, about 5.2 inches a year, mostly in January and February. The state Division of Air Quality counts pollen at its Raleigh lab from late February through mid November, with the peak in March and April.
January is the coldest month, with a normal low of 31.8 degrees, and it also brings the most snow, about 2.6 inches on average, with February adding about 1.4. A day or two of an inch or more is typical in a whole year, so the challenge is less snow than wet, half-frozen ground. Clay and slush come in on boots.
This is the hardest stretch of the year for Raleigh homes. Oaks and pines flower, and the state's peak days generally land between 1,000 and 1,500 grains per cubic meter, several times its 270 grain threshold for a high day. The highest count ever logged in Raleigh, 3,524, came on April 6, 2010.
Once tree pollen fades, it is the right moment for a One-Time Deep Clean: blinds, fans, vents and baseboards all carry the spring residue. Air quality can still swing. On June 7, 2023, smoke from Canadian wildfires put all of North Carolina under Code Red and Code Orange air quality alerts, and fine smoke particles settle on surfaces just like pollen does. On alert days, keep windows closed and dust with damp cloths afterward.
July is the hottest month, with a normal high of 90.8 degrees and a normal low of 70.2. The average dew point is about 68.7 degrees in July and 67.8 in August, so bathrooms, laundry rooms and closets hold moisture. July is also one of the two wettest months, at about 5.02 inches.
September is the wettest month at the airport, about 5.15 inches. Hurricane Fran struck North Carolina on September 5, 1996, causing heavy damage to homes and businesses across Wake County. Keep towels and a wet vac handy for storm days, and leave any water damage to a restoration specialist.
From mid September into October, stink bugs head for attics and garages, and lady beetles gather on sunny walls. Vacuum them up rather than squashing them, since crushed lady beetles can stain fabric and painted surfaces.
The pollen sampler shuts down in mid November, and leaf season takes over. In Chapel Hill, for example, the town collects leaves from November to January in town yard carts or paper bags, up to five containers a week, and does not pick up loose piles. Leaf bits and grit come inside on shoes, so this is a good time for a deep clean before holiday guests.
