North Little Rock draws its numbers from Little Rock AP Adams Fld, 258 feet up and 3.3 miles away. Its median first-freeze dates are 32°F by Nov 10, 28°F by Nov 21, 24°F by Dec 3. The 28°F freeze has come as early as Nov 6 and as late as Dec 8, a 32-day spread. Spring's last 32°F freeze clears around Mar 21. Snowfall averages 4 inches a year, first reaching an inch near January.

In North Little Rock, freezing nights (32°F) typically begin around Nov 10 and the first hard freeze (28°F) follows near Nov 21. Year to year, the first 32°F night has fallen anywhere from Oct 29 to Nov 25 — about 27 days apart. Spring's final freeze lands near Mar 21 and as late as Apr 6, so that is when outdoor water and stored gear can safely come back online. Snow is light here, near 4 inches a year, so pipe and battery cold usually matters more than plowing.

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

Compared with nearby cities, North Little Rock's first-freeze date near Nov 21 sits close to Little Rock (Nov 21) and later than Conway (Nov 11). Arkansas's deadlines span Oct 25 to Nov 19 statewide — one date for all of Arkansas would be off by weeks for North Little Rock. Once you know North Little Rock's freeze date, use it to shut down your sprinklers and winterize a boat too.

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 North Little Rock?
Wait until the last spring freeze has passed, which averages near Mar 21 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.
