Data: National Weather Service. Verdicts use freeze-thaw thresholds from maple field research; your woods may run a little differently.
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. Tap south-facing slopes first — they warm and run earlier.
Only three NASS seasons exist for West Virginia (estimates ran 2016–2018), so treat the median as indicative. It has the earliest median opening date of any NASS state.
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.

Common questions
- When is maple syrup season in West Virginia?
- Usually from early February to mid-March — about 5 weeks. The exact start moves by weeks from year to year with the weather.
- When should I tap my trees in West Virginia?
- 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 4. Tapholes dry up within 6 to 10 weeks, so tapping far too early can cost you the late runs.
- What weather makes sap run?
- Freezing nights and thawing days. Field research counts a freeze-thaw day as a low under about 30°F and a high over about 37°F; nights in the 20s and days in the 40s are the classic sap days.
