At Concord, the typical date of the first measurable snowfall (0.1 inch or more in a day) is Nov 20. 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 2, and in 1 in 10 not until Dec 23 or later. The earliest was Oct 23 (2002-03) and the latest Jan 13 (1999-00). A first snowfall of at least 1 inch in a single day typically arrives around Dec 4, and 100% of seasons had one. The first freeze of fall (a low of 32°F or colder) typically comes around Oct 2, and the last freeze of spring around May 13.

This season so far (2026-27, data through Oct 16, 2026): no measurable snow recorded yet; first freeze (32°F or colder) Oct 7 at this station. Compare with the typical dates above. This is observed data and can lag by a day or two, and it is not a forecast.

The median stretch between the last spring freeze and the first fall freeze (the freeze-free season) was about 140 days.
