Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Utica Oneida Co Airport.

Natural hazards →Marcy and its neighbors
Trenton has the coldest January nights next door (11°, 1° colder) and Utica the hottest July afternoons (82°, 2° warmer). Differences under a degree are within what the 5 km grid can tell apart. Tap a town to see its climate.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Marcy averaged 1.4° warmer than the 1900s. The biggest change is in December (+3.3°).
A bigger shift than in 50% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
