What a year in Delhi feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 132 frost-free days a year
In half of years the last 32° night comes by May 19 and the first by October 1. Frost and day counts come from NOAA’s station at Delhi 2 Se, NY, 1.3 miles from the town’s center, 430 ft lower.
The 2023 USDA map puts Delhi’s center in zone 5a: the coldest night of a typical winter, averaged over 1991–2020, reaches about −15°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Delhi
96% 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 Delhi 2 Se, NY.
Living with Delhi’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
132 frost-free days in zone 5a. The last frost comes by May 19 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 1.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August and September. 12 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Delhi 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.

Climates most like Delhi’s, farther away
TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Delhi, NY | 13° | 79° | 46" | 71" |
| Topsham, ME | 13° | 79° | 48" | 67" |
| Rindge, NH | 13° | 80° | 48" | 73" |
| Gardner, MA | 14° | 80° | 49" | 75" |
| Bradford, PA | 15° | 80° | 44" | 75" |
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 Delhi averaged 1.2° warmer than the 1900s. The biggest change is in December (+2.9°).
A smaller shift than in 63% 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 Delhi compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Delhi’s place among New York’s.
