ON TRACK106 days until first 28°F freezeOct 25

In a typical year, winterize your RV in Eden Prairie by October 15. The median first 28°F hard freeze at Eden Prairie's NOAA station is October 25 (1991–2020 normals); one year in ten it arrives as early as October 9. Plan for the early end: the one-in-ten date lands about 16 days before the median.

NOAA station: Mpls Flying Cloud AP · 1.6 mi away · 907 ft elevation.

The reference station for Eden Prairie is Mpls Flying Cloud AP (1.6 mi, 907 ft). First freeze there: 32°F by Oct 14, 28°F by Oct 25, 24°F by Nov 4. That hard freeze has landed anywhere from Oct 9 to Nov 8, a swing of roughly 30 days. Spring's last 32°F freeze clears around Apr 23. Snowfall averages 55 inches a year, first reaching an inch near November.

Eden Prairie usually sees its first 32°F night about Oct 14, with the first 28°F hard freeze close behind near Oct 25. That first freezing night has ranged from Sep 28 to Oct 28, roughly a 30-day spread. On the spring side, the last 32°F freeze clears around Apr 23 and as late as May 6 — the green light for reopening water and de-winterizing. Snow totals near 55 inches a year mean plowing and ice-dam control share the winter to-do list here.

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.

  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

Eden Prairie freezes close to Minnetonka (Oct 25) and close to Shakopee (Oct 25) — a reminder that even nearby towns differ by days. Statewide, Minnesota prep dates run Sep 28 through Oct 19, which is why Eden Prairie gets its own number rather than a Minnesota-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 Eden Prairie?
Wait until the last spring freeze has passed, which averages near Apr 23 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.
