Timing your taps

How to know it's time in Massachusetts

Sap runs on a temperature swing, not a date. A night below freezing loads the tree; a day above freezing pushes sap out of the taphole. Field research treats a low under about 30°F followed by a high over about 37°F as a real freeze-thaw day, and big runs almost always come on days like that.

So watch the 10-day forecast. When you see a string of nights in the 20s and afternoons in the 40s, get your taps in a day or two ahead. South-facing slopes warm first and usually run earlier.

Dates are USDA NASS approximate state averages. NASS dropped Massachusetts from its maple program after 2018, so there is no newer per-year data.

Massachusetts made 49,000 gallons of maple syrup in 2026, 0.8% of the US crop (USDA NASS). See every state’s crop.

Seasons are shifting. In New England and New York, the sugaring season now begins about 8 days earlier and ends about 11 days earlier than it did 40 years earlier, leaving it roughly 3 days (about 10%) shorter, according to UVM Proctor Maple Research Center survey records analyzed in 2007.

FAQ

Massachusetts tapping questions

When is maple syrup season in Massachusetts?
Usually from late February to early April, about 5 weeks. The exact start moves by weeks from year to year with the weather.
When should I tap my trees in Massachusetts?
Tap just before the first good run: when the forecast shows nights below freezing and days climbing to around 40°F. In a typical year that's around February 24. Tapholes dry up within 6 to 10 weeks, so tapping far too early can cost you the late runs.
What's the earliest maple season has started in Massachusetts?
In USDA records for 2011–2018, the earliest average opening was February 18 (2018) and the latest was March 14 (2015), a spread of 24 days.
