Cleveland's weather changes what comes into a home every few weeks. This calendar uses NOAA normals for Hopkins Airport and local leaf schedules to say what to clean, and when, through the whole year.
Cleveland's year has a rhythm most residents could recite: a long snowy winter with the lake doing its work, a spring that keeps taking a step back, a short humid summer, and a fall that ends in leaf piles on every tree lawn. Each phase leaves its own mess.
The calendar below groups the months by what they bring in. The numbers come from NOAA's 1991 to 2020 normals for Cleveland Hopkins Airport, and from the leaf and trash schedules the suburbs publish.
Normal annual snowfall at Hopkins is 63.8 inches, and normal precipitation is 41.03 inches spread fairly evenly through the year, with September the wettest month at 3.93 inches. About 89 days a year bring at least a tenth of an inch of rain or melted snow.
Cold dominates the calendar. Hopkins averages about 111 days with a low at or below freezing and about 37 days when the high never gets past 32 degrees. At the other end, the normal July high is 83.7 degrees and there are about 12 days a year at 90 or hotter.
December brings 12.2 inches of snow on average, January 18.4 and February 15.1. Lake-effect bands typically keep hitting the East Side until Lake Erie freezes, and in the Heights a season can total near or above 100 inches. This is the stretch when an inch or more of snow sits on the ground for weeks at a time.
Focus on the entry, the stairs and the kitchen floor, where salt brine dries into a white crust. Wash mats weekly, wipe baseboards near doors, and keep a boot tray at every door people actually use. Dew points around 21 degrees in January mean dry indoor air, so static pulls dust onto screens and electronics; a damp cloth works better than a dry duster.
March is not spring in Cleveland. It averages 10.8 inches of snow, and April still brings 2.7, but normal highs climb from 47.1 degrees to 60.1. Melting snow turns tree lawns into mud, and the dirt that comes in changes from salt to soil.
This is the season for the big reset. Once the last salt is gone, wash every baseboard, clean window tracks, wipe blinds and take down ceiling fan dust from the closed-up months. Beachwood also picks up loose leaves again in April, so clearing the yard and the house can happen the same week.
Warm months mean windows up and pollen on sills. The Asthma and Allergy Foundation of America's 2026 report ranks Cleveland 65th of the 100 largest metros for seasonal allergies, which is middle of the pack, but a yellow film on porch furniture and window ledges is still part of every spring.
By July the air is sticky. Mean dew points reach about 62 degrees in July and 61.5 in August, so bathrooms take longer to dry after showers. Run exhaust fans longer, keep shower glass squeegeed and wipe the kitchen often when the windows are up and insects find crumbs.
September is Cleveland's wettest month at 3.93 inches, and then the leaves come down. Beachwood collects loose leaves from the tree lawn from the last week of September into mid-December. Solon's 2025 program ran from October 13 to December 12. Rocky River's 2026 collection officially starts on November 2 and moves north to south, and Strongsville makes one pass per street in set weeks.
Wet leaves stick to shoes and paws and end up on entry rugs. Before lake-effect snow typically begins in mid-November, use the last mild weeks to clean the furnace vents, wash the windows once more and get the home ready to be closed up for winter.
