When does it first snow in Bangor, ME?

At Bangor, the typical date of the first measurable snowfall (0.1 inch or more in a day) is Nov 22. That is the median over the last 30 snow seasons: half of seasons saw it earlier, half later. In about 1 season in 10 it came by Nov 1, and in 1 in 10 not until Dec 6 or later. The earliest was Oct 10 (2000-01) and the latest Dec 11 (1999-00). A first snowfall of at least 1 inch in a single day typically arrives around Nov 23, and 100% of seasons had one. The first freeze of fall (a low of 32°F or colder) typically comes around Oct 6, and the last freeze of spring around May 9.

Based on the station’s daily minimum temperature, 1995–2024. “Freeze” here means a daily low at or below the threshold, which is not the same as visible frost. Your yard can differ by several degrees and days from an airport weather station, so use these as planning odds, not guarantees.

The median stretch between the last spring freeze and the first fall freeze (the freeze-free season) was about 150 days.
