January nights here settle around 9°. Winter nights are cold: in January they are colder than in 95% of U.S. towns. Warming shows here too: 1.3° more than in 1901–2000, led by December. Garden planting can start around May 4; autumn frost returns near October 13.

What stands out about Norway’s climate
Compared with towns across the U.S., with Norway’s place in New York beside it.
What a year in Norway feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 161 frost-free days a year
In half of years the last 32° night comes by May 4 and the first by October 13. Frost and day counts come from Trenton Falls, NY, 11 miles away.
The 2023 USDA map puts Norway’s center in zone 5a: the coldest night of a typical winter, averaged over 1991–2020, reaches about −18°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Norway
95% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through May.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Trenton Falls, NY.
Living with Norway’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
161 frost-free days in zone 5a. The last frost comes by May 4 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Oct 13.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August and September. 1.6 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Norway from natural hazards, river flooding is the largest share (85%); heat waves, cold waves, winter storms and ice storms together are 6%. Normals are averages; the hazards page covers the extremes.
Natural hazards →Norway and its neighbors
Ohio has the coldest January nights next door (5°, 4° colder) and Newport the hottest July afternoons (81°, 3° 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 Norway averaged 1.3° warmer than the 1900s. The biggest change is in December (+3.3°).
A smaller shift than in 57% 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.
How Norway compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Norway’s place among New York’s.

How much a month can swing
A normal is an average. March swings the most: from 1991 to 2020 its average ranged from 20° to 41°. August is the most reliable, staying within 7°.
