The RV Winterize-By Calendar: in a typical US city, winterize by October 17
We matched 320 of the biggest RV storage cities in our directory to their nearest NOAA weather station and read the 1991-2020 freeze normals. Our winterize-by date is the day by which there is only a 10% chance of a 32°F freeze, so you beat the first frost in nine years out of ten. In the median city it is October 17, two weeks before the median first freeze on October 31.

Key findings
- October 17 is the median winterize-by date across the 295 cities that freeze in most winters. Their median first freeze is October 31.
- The safe date is about two weeks before the median freeze. In the typical city the 10% date comes 14 days before the 50% date; the gap ranges from 10 to 31 days.
- 61 cities should winterize in August or September, led by Kalispell, MT (Aug 26), Soldotna, AK (Aug 29) and Bend, OR (Sep 3).
- 150 cities fall in October and 75 in November. Denver's date is Sep 25, Chicago's Oct 20, Dallas's Nov 10 and Houston's Nov 17.
- 25 cities rarely or never freeze, including Miami, Los Angeles, San Diego, Honolulu and Phoenix. Some still see a frost in a cold year.
When to winterize, city by city
A frozen water line can crack fittings, a water pump or a water heater tank. The safest time to winterize is before the first freeze, but the first freeze moves around from year to year. NOAA's climate normals give the date by which a first fall freeze has a 10%, 50% or 90% chance of having happened. We use the 10% date as the winterize-by date: if you are done by then, nine years in ten you beat the first 32°F night.
The biggest group lands in October: 75 cities between October 1 and 15 and 75 more between October 16 and 31. The northern Rockies, the high desert, the northern Plains and Alaska come first, in late August and September. The Gulf Coast, Florida and the low deserts of Arizona and Nevada come last, in late November and December, if they freeze at all.
The earliest first freeze in each state
In 20 states at least one of the cities we checked reaches its median first freeze by October 15, and 20 more reach it in the second half of October. Only Arizona and Hawaii have no city with a median freeze before December; in Arizona that reflects the low-desert cities where most storage is, not the high country around Flagstaff.

Sorted from earliest to latest winterize-by date. Fall dates in January or February are in the following year. "Rare" means the station has no freeze in at least half of years; the date shown applies to the years that do freeze. "Rarely" in the hard-freeze column means NOAA gives no 28°F date.

What it means for you
- Use the date for where the RV is stored, not where you live. A rig stored in the foothills can freeze weeks before one in town.
- Book early. Winterizing searches peak in October and November, according to The RV Owner's Year. Shops fill up the week of the first forecast frost.
- Don't wait for the median. The median first freeze is a coin flip. Our winterize-by date is about two weeks earlier in the typical city, which is the margin that protects the plumbing.
- Watch the hard-freeze date. At 28°F and below, exposed lines and low-point drains freeze faster. In the typical city the median hard freeze comes 11 days after the median first freeze.
- De-winterize after the last spring freeze. The median last spring freeze is a coin flip too; wait a week or two past it before you refill the system.
- Indoor or climate-controlled storage lowers the risk but doesn't remove it. Unheated buildings still freeze. Compare indoor and climate-controlled RV storage near you, and winterize anyway unless the space is heated.

How we did this
- We took 320 cities with the most storage facilities in our directory, at least five per state where available, and placed each at the median location of its facilities.
- Each city was matched to the nearest NOAA station with 1991-2020 freeze normals (median distance 5.75 miles; the farthest is 29.7 miles, Katy, TX). The table names the station and its distance.
- Winterize by = the first fall date with a 10% probability of a 32°F freeze (PRBFST-T32FP10). Median first freeze = the 50% date (T32FP50). Hard freeze = the 50% date for 28°F (T28FP50). Last spring freeze = the 50% date for the last 32°F night (PRBLST-T32FP50).
- Where NOAA reports no freeze dates (11 cities) we show "No freeze in normals". Where the median growing season is 364 days or more (14 cities), freezes happen in fewer than half of years; we mark these "Rare" and show the date for the years that do freeze. Fall dates in January or February belong to the following year.
- Data compiled October 25, 2026. Normals describe the past 30 years and one station; local conditions and individual years vary.

Questions people ask
When should I winterize my RV?
Before your local winterize-by date, the day by which there is a 10% chance of a first 32°F freeze. Across the 295 cities in our table that freeze in most winters, the median is October 17, about two weeks before the median first freeze on October 31. Look up the city where the RV is stored.
What is the earliest place to winterize an RV?
Among our 320 cities, Kalispell, MT has the earliest winterize-by date at August 26, followed by Soldotna, AK (August 29) and Bend, OR (September 3). In total 61 cities, mostly in the northern Rockies, high desert, northern Plains and Alaska, fall in August or September.
Do I need to winterize my RV in Florida, Arizona or Southern California?
In Miami, Los Angeles, San Diego and Honolulu, NOAA reports no freeze dates. Phoenix, Tampa and several Florida cities freeze in fewer than half of winters. Northern Florida does freeze: Jacksonville's winterize-by date is November 30. In rare-freeze cities, watch the forecast and drain or protect the lines when a frost is predicted.
What is the difference between a freeze and a hard freeze?
A freeze here means the low reaches 32°F. A hard freeze is 28°F or below, cold enough to freeze water in exposed lines quickly. In Chicago the median first freeze is October 31 and the median hard freeze November 11; in Denver they are October 8 and October 18.
