Natural hazards →Newport and its neighbors
Norway has the coldest January nights next door (9°, 2° colder) and Schuyler the hottest July afternoons (82°, 1° 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 Newport averaged 1.2° warmer than the 1900s. The biggest change is in December (+3.2°).
A smaller shift than in 60% 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.
