When to Winterize Your RV in Lincoln Park, MI

ON TRACK109 days until first 28°F freezeOct 28

In a typical year, winterize your RV in Lincoln Park by October 18. The median first 28°F hard freeze at Lincoln Park's NOAA station is October 28 (1991–2020 normals); one year in ten it arrives as early as October 13. The early-odds date runs roughly 15 days ahead of the median, so build in that buffer.

NOAA station: Dearborn · 5.6 mi away · 605 ft elevation.

Lincoln Park draws its numbers from Dearborn, 605 feet up and 5.6 miles away. Its median first-freeze dates are 32°F by Oct 15, 28°F by Oct 28, 24°F by Nov 10. That hard freeze has landed anywhere from Oct 13 to Nov 12, a swing of roughly 30 days. Spring's last 32°F freeze clears around May 1. Snowfall averages 31 inches a year, first reaching an inch near December.

In Lincoln Park, freezing nights (32°F) typically begin around Oct 15 and the first hard freeze (28°F) follows near Oct 28. The 32°F date swings from Oct 1 at its earliest to Oct 28 at its latest, near 27 days. The last spring freeze averages May 1 and as late as May 18, which sets the safe window for reopening outdoor water and de-winterizing gear. About 31 inches of snow a year is enough to justify servicing the snow blower and watching the eaves.

Your rv checklist

  1. Drain the fresh, gray, and black tanks, then drain the water heater only after it has cooled and lost pressure.
  2. Bypass the water heater so you do not waste six gallons of antifreeze filling the tank.
  3. Blow out the lines with a compressor at about 30–40 psi, then pump non-toxic RV antifreeze through every faucet until it runs pink.
    Helpful gear: RV antifreeze (6-pack) — Recommended pick
  4. Use a water-pump converter kit to draw antifreeze straight from the jug through the plumbing.
    Helpful gear: Water pump converter kit — Recommended pick
  5. Pour a cup of antifreeze into each drain trap and the toilet to protect the seals.
  6. Fit a blow-out plug at the city-water inlet so you can clear that line too.
    Helpful gear: Blow-out plug — Recommended pick
  7. Remove batteries or put them on a maintainer, and store them off a cold concrete floor.
  8. Cover roof vents, close the propane, and set out traps or deterrents so mice do not move in.

What this means locally

Lincoln Park freezes about a week ahead of Taylor (Nov 7) and about a week ahead of Dearborn (Nov 6) — a reminder that even nearby towns differ by days. Statewide, Michigan prep dates run Oct 13 through Oct 30, which is why Lincoln Park gets its own number rather than a Michigan-wide average. The same freeze also decides when to shut down your sprinklers and winterize a boat.

Frequently asked questions

At what temperature do RV pipes freeze?
An RV's exposed plumbing and thin-walled tanks can begin to freeze once temperatures sit in the mid-20s for a few hours, sooner than a house because there is little insulation around the lines. That is why the winterizing deadline tracks the first 28°F freeze rather than the first light frost.
How much RV antifreeze do I need?
Most travel trailers and motorhomes take about two to three gallons of non-toxic RV antifreeze, and larger rigs more. Bypassing the water heater saves roughly six gallons you would otherwise waste filling the tank. Buy an extra jug; stores sell out once the first freeze warnings hit.
Can I just use my RV furnace instead of winterizing?
Relying on the furnace is risky. A propane run-out, a tripped breaker, or a dead battery during a cold night leaves the plumbing unprotected, and the furnace may not keep the underbelly and bays warm enough anyway. Draining and adding antifreeze is the dependable way to protect the system.
How do I winterize an RV water heater?
Let the tank cool and lose pressure, then drain it and, if fitted, pull the anode rod. Do not add antifreeze to the water heater tank; instead, set the bypass valves so antifreeze skips the tank and fills only the lines. Fresh antifreeze in an unbypassed heater just wastes several gallons.
When is it safe to de-winterize an RV in Lincoln Park?
Wait until the last spring freeze has passed, which averages near May 1 here. De-winterize by flushing the antifreeze from the lines, sanitizing the fresh tank, and checking for leaks before a trip. Reopening too early risks a surprise late freeze on a charged system.
Do I need to winterize an RV stored indoors?
A reliably heated indoor space that stays above freezing protects the plumbing, so full winterizing may not be needed. But an unheated garage or barn can still drop below freezing on a cold night. If you cannot guarantee the space stays warm, winterize to be safe.
