Aurora Seasonal Water Risk Calendar: Month by Month

Through the year

Weather varies a lot from year to year on the Front Range. Treat this as a general pattern, not a forecast.

December to February: Arctic cold snaps freeze pipes in garages, outside walls and unheated commercial vestibules. Fire sprinkler lines in cold areas are at risk. Snow piles can block sump discharge lines.
March and April: Heavy, wet spring snowstorms are common. Snowmelt saturates soil around foundations, and sump pits start working harder. Roof drains and gutters can clog with ice.
May and June: Thunderstorm and hail season ramps up. Window wells fill, gutters overflow, and hail cracks roofing, skylights and rooftop equipment on commercial buildings.
July and August: Afternoon downpours continue. Air conditioning condensate lines and drain pans on rooftop units and furnaces are a frequent source of ceiling leaks.
September and October: Irrigation season ends. Sprinkler systems need blowing out and outdoor faucets need hoses removed before the first hard freeze, which can come early.
November: First sustained cold. Vacant units, vacation homes and closed retail spaces should keep heat on and have water checked or shut off.

Winter	Keep garage door closed in cold snaps; know the main shutoff	Report cold units or drafts near pipes; keep heat on when away	Check heat in vestibules, loading docks and sprinkler riser rooms

Summer	Clear hail from wells and gutters after storms	Check AC condensate line in closets	Inspect condensate pans; check roof after hail
Fall	Blow out irrigation; remove hoses; check water heater	Confirm who winterizes common irrigation	Winterize irrigation; review cold-weather plan for sprinklers

Set the thermostat to a temperature that keeps the whole house above freezing
Open cabinet doors under sinks on outside walls
Consider shutting off the main water valve and draining lines if leaving for a long time
Ask a neighbor to check the house during a cold snap
Install a leak sensor or smart shutoff that alerts your phone
Make sure the sump pump is plugged in and its discharge is clear of snow
