Snow in Rochester: common questions

How much snow does Rochester get in a year?

About 102 in in an average year — the 1991–2020 NOAA normal at Rochester Greater International Airport, NY, about 4 mi from central Rochester. The snowiest month there is January, with 27 in on average.

Why doesn't this match the snow on my deck in Rochester?

The figure above is NOAA's estimate for one ~4 km grid cell near the town centre, not a measurement in your yard. Snow drifts, settles and melts, and totals can change a lot over a few miles. NOAA also revises each estimate for about five days as late spotter reports come in.

Is this a forecast or what actually fell?

Both, kept apart. The three totals are NOAA's estimate of snow that already fell, for fixed windows that end at 12:00 or 00:00 UTC (7 am or 7 pm Eastern in winter). The table below them is the National Weather Service forecast for the next 72 hours.

Can I check my own address instead of downtown?

Yes — the snow lookup takes any ZIP code in the contiguous US, or your location, and shows the same three totals and the forecast for the ~4 km cell you are in.

Where these numbers come from

Snow that fell: NOAA National Snowfall Analysis
Published by NOAA’s National Operational Hydrologic Remote Sensing Center (NOHRSC) on a ~4 km grid of the contiguous US. It blends radar-based precipitation estimates, a snow-to-liquid ratio and reports from volunteer and cooperative observers. 24-hour totals end at 12:00 and 00:00 UTC and appear about two hours later; 72-hour and season totals are built from the daily 12:00 UTC analysis. NOAA re-runs each analysis for about five days as late reports arrive, so a total can change.
Snow that’s coming: National Weather Service
The NWS gridpoint forecast for the spot: snowfall, ice, temperature, chance of precipitation and wind in 6-hour steps for the next 72 hours.
On this page: 30-year averages
From the NOAA NCEI U.S. Climate Normals, 1991-2020, retrieved 2026-10-30, for one named weather station, with its distance from the town.
What it cannot tell you
A grid estimate is not a ruler in your yard. Snow drifts, settles and melts; totals can change a lot within a few miles; and narrow lake-effect bands can fall between grid cells. Treat these numbers as a good estimate for your area, not a measurement at your door.
