ON TRACK143 days until first 28°F freezeDec 1
The first 28°F freeze near West New York averages December 1 (1991–2020 normals) — enough to crack an unprotected block even where owners assume they're safe — so winterize the boat by November 24. Year to year the date swings about 31 days, which is why the live outlook beats the calendar.

- West New York has one of the later first freezes, so watch the live outlook for the odd early cold night.
The reference station for West New York is New York Cntrl Pk Twr (2.4 mi, 130 ft). First freeze there: 32°F by Nov 20, 28°F by Dec 1, 24°F by Dec 12. The 28°F freeze has come as early as Nov 15 and as late as Dec 16, a 31-day spread. Spring's last 32°F freeze clears around Mar 30. Snowfall averages 30 inches a year, first reaching an inch near December.
The freeze arrives in two steps in West New York: 32°F around Nov 20, then a hard 28°F near Dec 1. Year to year, the first 32°F night has fallen anywhere from Nov 6 to Dec 6 — about 30 days apart. Spring's final freeze lands near Mar 30 and as late as Apr 9, so that is when outdoor water and stored gear can safely come back online. Snowfall averages roughly 30 inches a year — enough that a working snow blower and a clear roof edge earn their keep.
Your boat checklist
- Change the engine oil and filter while the motor is warm so contaminants leave with the old oil.
- Run the engine on antifreeze until pink fluid reaches the outlet, protecting the block and manifolds.Helpful gear: Marine antifreeze — Recommended pick
- Fog the cylinders with fogging oil as the engine runs down to coat internal parts against corrosion.Helpful gear: Fogging oil — Recommended pick
- Top off the fuel tank and add stabilizer to limit condensation and protect ethanol-blend fuel.Helpful gear: Marine fuel stabilizer — Recommended pick
- Drain the raw-water system, the livewell, and any washdown lines that can trap water.
- Remove the battery, charge it fully, and keep it on a maintainer over the layup.Helpful gear: Battery maintainer — Recommended pick
- Support the cover so snow and rain shed off, and leave vents so the interior can breathe.
- For an inboard or sterndrive, follow the manual closely — those blocks are the ones freeze claims hit hardest.

Warm states file the most freeze claims — Texas tops the BoatUS list, ahead of New York and New Jersey, because southern boaters skip winterizing or trust space heaters that fail in outages.
BoatUSCracked engine block repair, often exceeding $10,000 with a replacement long block and labor — versus $100–$800 for professional winterization by engine type.
Discover BoatingTypical boat shrink-wrap cost per foot of boat length; a 21–30 ft boat usually totals $300–$1,000 including arch and tower allowances.
Discover BoatingWhat this means locally
Against its neighbors, West New York (first freeze Dec 1) runs close to Hoboken (Dec 1) and close to New York (Dec 1). Across New Jersey, local prep deadlines in our data range from Oct 31 to Nov 25, so a statewide rule of thumb would miss West New York by weeks. In West New York, that same cold is your cue to winterize an RV and store a motorcycle. Keeping an eye on the rest of the county? The same local math is on our Vineland and Atlantic City pages.

Frequently asked questions
At what temperature does a boat engine block crack?
Trapped water in an engine block or manifold can freeze and crack the casting once temperatures fall below 32°F and stay there long enough. Inboard and sterndrive blocks hold the most water and are the most vulnerable. Draining fully and adding antifreeze before the first hard freeze near Dec 1 is the protection.
Do outboards need winterizing?
Yes. An outboard should be drained so no water sits in the powerhead or lower unit, and the fuel system stabilized. Outboards self-drain better than inboards when tilted down, but fogging the cylinders and changing the gear oil are still part of a proper layup.
Fogging oil: is it necessary?
Fogging coats the cylinder walls and internal parts with a film that resists corrosion during months of storage. On engines that sit all winter it is cheap insurance against rust, especially in humid or coastal storage. Follow your engine maker's guidance on how to apply it.
How much does boat winterization cost?
A professional winterization varies with engine type and boat size, and inboards cost more than a simple outboard. Doing it yourself costs mainly antifreeze, oil, and fogging oil. Either way, the bill is far smaller than repairing a cracked block, which is the failure winterizing prevents.
Do boats in NJ really need winterizing?
If temperatures reach freezing where the boat is stored, yes. Freeze claims are common in milder states precisely because owners assume they are safe and skip the step, then a rare cold snap cracks a block. Check the local freeze dates above and protect the engine before the first hard freeze.
When should I de-winterize my boat?
De-winterize in spring once the risk of a hard freeze has passed for your area. Reconnect and charge the battery, replace drain plugs, check hoses and clamps, and inspect the fuel system before the first launch. Reopening too early leaves the block exposed to a late cold snap.
Does boat insurance cover freeze damage?
Usually not by default — ice and freeze damage is excluded from most marine policies as a maintenance issue unless you add a specific rider (roughly $20–$55 per year, typically only purchasable until the end of October). Even with the rider, insurers may ask for proof of proper winterization, so keep the receipt.
