Has the climate in Bar Harbor changed?
Bar Harbor has warmed about 3.3°F between 1983 and 2013.
About 1.1°F per decade, measured from Bar Harbor's official daily weather records, 1983–2013. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
What has actually changed
Each card compares the 1970s (the first ten years of the record) with recent years (the last ten) — the same span the headline and the chart use.
Bar Harbor's temperature, year by year
Average temperature for each year from 1983 to 2013.
Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.
In day-to-day terms, that long-term shift shows up as about 8 fewer freezing nights a year compared with the 1970s.
Methodology & sources
Temperature — 1991–2020 normals computed from 23 years of daily observations at Acadia NP, a weather station, about 5 km from the city centre. The underlying daily records come from NOAA's global station network.
