The Post-Christmas Blizzard of 2025 as Long Island’s embrace their First Major Snow Since 2010. As the holiday lights still twinkle and leftover wrapping paper litters living rooms across Long Island, a classic winter surprise rolled in on December 26, 2025. What many hoped would be a quiet post-Christmas weekend turned into a full-blown snow event—the kind that demands shovels, snowblowers, and maybe a day off to recover. For the first time in 15 years, Long Island saw a genuine major snowstorm arrive after Christmas Day, echoing the infamous Boxing Day Blizzard of 2010.
A Long Wait Ends
The last time a significant, plowable snow dumped on Long Island so late in December was December 26–27, 2010. That storm delivered 15–20+ inches in many spots, shutting down roads, airports, and life for days. Since then, late-December weather has been remarkably tame—no blockbuster accumulations on or after the 26th. Early December snows popped up in some years, but nothing hit the post-holiday mark with real impact. Until now. There was large amount of snow in Mid December like 2020 and 2025. There was snowstorms outside of Christmas in winter 2021 and January 2022 which nothing major happened since then.
This 2025 system broke that drought. Forecasters and residents alike noted the rarity: the first major post-Christmas snow since 2010. It wasn’t just a dusting; it was the kind of event that earns a Winter Storm Warning and makes headlines as “NYC’s biggest in years.”
How the Storm Unfolded
The action started late Friday, December 26. Flurries and light snow appeared around sunset (roughly 4–6 p.m. in many areas), but the real punch arrived overnight. Heaviest bands fell between midnight and 6 a.m. on Saturday, December 27, before tapering off by midday.
- Timing: Snow ramped up fast Friday evening, peaked overnight, and wound down Saturday morning—perfect for disrupting post-holiday travel but mercifully short-lived.
- Temperatures: Lows in the 20s, highs struggling to reach the mid-30s, with wind chills dipping into the teens. Classic raw Northeast winter feel.
- Hazards: Slippery roads, reduced visibility in heavier bands, and potential brief sleet mixes (especially nearer the coast or NYC border) as warmer air briefly clashed with the cold.
Winter Storm Warnings covered Nassau and Suffolk Counties, NYC, and much of the Tri-State from 4 p.m. Friday until 1 p.m. Saturday. Travel advisories urged caution—post-Christmas returns, airport runs, and family visits all faced delays.
Snow Totals: A Solid Blanket for Most of the Island
Projections held steady, with widespread accumulation:
- Western and central Long Island (Nassau, western Suffolk): Commonly 5–9 inches, with some spots pushing 8–10 inches in stronger bands.
- Eastern Long Island (farther out Suffolk, East End): Lighter, typically 3–6 inches, though still enough to shovel.
- Overall island average: Around 5–8 inches in many areas, qualifying as a significant event.
The National Weather Service (NWS Upton) and outlets like FOX 5 NY, News 12 Long Island, and AccuWeather consistently highlighted higher totals for western Long Island and the NYC metro, tapering eastward. This made it a “west-heavy” storm—great news if you’re in Mineola or Hempstead, a bit less so if you’re out toward Montauk (but still respectable).
Why It Felt Like a Big Deal
After several quieter winters, even 5–6 inches feels major. The storm ended a streak without 4+ inch events in Central Park since early 2022, and it brought the first Winter Storm Warning to the region in nearly four years. Media called it potentially NYC’s heaviest since January 2022, with Long Island sharing in the bounty. Add the post-holiday timing—people unwinding, traveling back, or hitting sales—and the disruption amplified the impact.
Looking Ahead
As the flakes settle and plows clear the way, temperatures stay cold into the New Year. This could set the tone for a wintry finish to 2025. For now, though, Long Islanders are digging out, building snowmen, and reminding themselves why winter here is equal parts beautiful and brutal.
If you’re on the Island reading this while sipping hot cocoa, stay safe, check your local forecasts (NWS Upton is the go-to), and enjoy the rare post-Christmas wonder. It’s been 15 years in the making—might as well make the most of it. ❄️
Stay warm, bundle up, and happy (belated) holidays!
Snow Totals: A Solid Blanket for Most of the Island
Now that the storm has fully concluded as of December 28, 2025, and final reports from the National Weather Service (NWS Upton), spotters, and local media are compiled, the accumulations show a fairly consistent, shovel-worthy blanket across Long Island—with Suffolk generally seeing the edge in totals.
• Nassau County: Widespread 4 to 6 inches, with isolated higher spots (e.g., Farmingdale at 5 inches as one of the top reports, Levittown pushing toward 7 inches in some readings, but most areas clustering in the mid-4 to low-6 range). Southern and western Nassau trended toward the lower end, while northern/central pockets fared slightly better.
• Suffolk County: Commonly 6 to 8 inches, with many reports in the 5.5–7 inch range (e.g., North Patchogue ~6.8 inches, Ridge 8 inches, Babylon and Orient 7.5 inches, Islip Airport 5.6–6.6 inches depending on source, Center Moriches ~6 inches). Heavier bands favored central and northern Suffolk.
• East End (eastern Suffolk, including areas like Riverhead, Mattituck, Orient, Remsenburg-Speonk, Flanders, Bridgehampton): Solid 5 to 7.5 inches, often in the 6–7 inch ballpark (e.g., Orient 7.5 inches, Mattituck 7 inches, Remsenburg-Speonk 6.3 inches, Riverhead 6.1 inches, Flanders 5.8 inches). Contrary to some pre-storm expectations of lighter eastern totals, the East End held strong and avoided the lightest side of the spectrum.
Overall island average hovered around 5–7 inches, making this a broadly even, significant event rather than wildly variable. Suffolk (including the East End) edged out Nassau in many spotter compilations, delivering a bit more punch where heavier overnight banding set up.
Why It Felt Like a Big Deal
After several quieter winters, even 5–6 inches feels major. The storm ended a streak without 4+ inch events in Central Park since early 2022 (Central Park itself saw ~4.3 inches), and it brought the first Winter Storm Warning to the region in nearly four years. Media called it potentially NYC’s heaviest since January 2022, with Long Island sharing in the bounty. Add the post-holiday timing—people unwinding, traveling back, or hitting sales—and the disruption amplified the impact.
This post-Christmas event serves as a timely reminder that winter can deliver surprises even in a season that started mild. The storm tapped into a quick shot of cold Canadian air clashing with lingering moisture, producing plowable snow across the island despite some sleet mixing that tempered totals in spots.
Looking ahead, the 2025-2026 winter outlook suggests potential for more action later in the season. A weak La Niña pattern (cooler equatorial Pacific waters) is in play through early 2026 before likely transitioning to neutral conditions by spring. Weak La Niña winters often bring variable impacts to the Northeast, including a tendency toward a more active storm track—potentially favoring colder outbreaks and increased chances of nor’easters or coastal storms in January through March.
