When is the best time to ski Sugarloaf? A weather guide built from the record

The source Sheet combines 69 completed annual snowfall totals from 1955–56 through 2023–24 with daily Sugarloaf-reported snowfall for 2019–20 through 2025–26. Monthly averages in this guide come from those seven recent daily logs. Dustings recorded as text are treated as zero inches, so the totals remain conservative and auditable.

This is not a forecast model. Resort snowfall measurement, wind redistribution, rain, grooming and terrain openings all affect skiing. The temperature tabs are partial snapshots rather than a climatological normal. Use the record to choose a travel window; use the current forecast and mountain report to choose a ski day.

January produced the highest recent monthly average—34.1 inches—and the most measurable snow days at 9.3. Every one of the seven seasons logged at least 19 inches, and the best reached 49. By this point, snowmaking has had sustained cold and natural snow has begun to build the woods.

The cost is temperature. In the partial temperature record, the base averaged roughly 22°F in January and the summit about 12°F. A cold northwest wind can make that difference feel much larger. January favors skiers who dress well, start early and accept that upper lifts may be the day's variable.

February averaged 29.3 inches, but its median was higher at 34 inches. Five of seven seasons landed between 23 and 44 inches; one seven-inch February pulled down the mean. That makes February the strongest choice when your goal is accumulated base plus repeated chances for a refresh.

It is also vacation season. Fresh snow does not guarantee empty trails, and wind can move traffic onto fewer lifts. If your dates are flexible, favor non-holiday weekdays and keep the arrival day clear enough to adjust around a storm.

Recent March totals range from 3 to 58 inches. That is the month in one line. A cold pattern can deliver the season's best natural terrain; a warm storm followed by refreeze can turn the same map into a firm groomer day.

The partial temperature sample puts the base near 33°F and the summit near 24°F on average. Timing becomes a skill: follow the sun, let frozen surfaces soften and stop skiing an aspect when it becomes heavy or scraped. March rewards travelers who can adjust their expectations by the hour.

December averaged 26.4 inches in the recent log, but natural-terrain coverage is still developing. It is a good month for groomers, snowmaking and holiday atmosphere—not the safest bet for Brackett Basin or every glade on the map.

April averaged a surprising 18.4 inches and produced a 43.5-inch outlier in 2019–20. Yet April decisions are governed by freeze-thaw cycles, operating schedules and overnight temperatures. Book it for sunshine, soft corn snow and a relaxed pace. Treat a powder day as a gift.

Across 69 completed historical seasons, the Sheet's average is 171.1 inches. The snowiest listed season, 1995–96, reached 389 inches; the leanest, 1964–65, recorded 77. The median of the seven recent seasons is 163 inches even though the recent average is only 148.9, showing how the 103- and 118-inch seasons pull the mean down.

That spread is why a single annual average should never be read as a promise. Snow can arrive early or late, in many small events or two large storms. Terrain quality depends on when it falls and what the temperature does next.
