Heating and cooling a home in Baltic
87% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through April.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Norwich Public Utility Plt, CT.
Living with Baltic’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
192 frost-free days in zone 6b. The last frost comes by Apr 14 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 24.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August, September and October. 0.0 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Baltic from natural hazards, river flooding is the largest share (80%); heat waves, cold waves, winter storms and ice storms together are 2%. Normals are averages; the hazards page covers the extremes.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Baltic, CT | 19° | 83° | 48" | 38" |
| Indiana, PA | 19° | 83° | 46" | 46" |

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 Baltic averaged 2.0° warmer than the 1900s. The biggest change is in December (+3.8°).
A bigger shift than in 91% 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 Baltic compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Baltic’s place among Connecticut’s.
