The biggest Boston snowstorms of the last ten winters
These are the five largest storms at Logan from winter 2016-17 through winter 2025-26. Each total is the heaviest three-day stretch of a storm, taken from daily observations, with no day counted twice. A storm that fell in one or two days shows the days it snowed.
| Rank | Dates | Snowfall at Logan |
|---|---|---|
| 1 | Jan. 28-29, 2022 | 23.8 in |
| 2 | Jan. 25-26, 2026 | 23.2 in |
| 3 | Feb. 21-23, 2026 | 17.9 in |

This is a ten-winter window, not the full record. For earlier storms, the National Weather Service Boston/Norton office keeps longer histories. The late-January 2026 storm measured 23.2 in at Logan, covered in the January 24-26, 2026 recap. For the latest winter across major cities, see winter 2025-26 snowfall totals by city.
Why Boston snowfall varies across the metro
In Boston, the track of the storm and the temperature of the air near the coast do most of the sorting. A storm that passes close to the coast can pull in milder air off the ocean, so the shoreline sees rain or sleet while towns inland, sometimes only a few miles away, collect heavy snow. A track farther offshore reverses that.
Logan sits on the harbor, so in a marginal storm the airport can read lower than the inland suburbs. In a strong coastal storm, narrow bands of intense snow can set up over one part of the region and miss another. The line between rain and snow, and where those bands land, often decides which neighborhoods get much more or much less than the airport. For that reason, the station total is a good picture of the winter and a rough guide to a single neighborhood.

Each verified email gets three free reports. After that, a report is $39, and a ZIP pass covers many reports in one ZIP code for 12 months. Details are on the pricing page.
About these numbers
All station totals come from the official National Weather Service record for Boston Logan International Airport, read through the NOAA Regional Climate Centers ACIS database and checked against a second official source, the National Weather Service daily climate reports or the NOAA NCEI daily archive. Where the preliminary climate report and the final archive differ by a few tenths on one day, this page uses the final archive. They are totals at one station. They are not an estimate for an address, and they are not a certified copy of the record. For certified copies, NOAA NCEI sells them through its data certification service.
