Regional context

In Manchester, NOAA NCEI 1991-2020 normals put January near 22°F and July near 71°F — a 49°F seasonal arc — with about 42.5 inches of precipitation over 81 rainy or snowy days.

No season owns Manchester's rain: October reaches 4.4 inches across 6.6 days and January keeps 2.7 inches on 6.6, an even spread through Manchester's year. It is a balanced pattern Manchester shares with places like South Hooksett, NH, Pinardville, NH and East Merrimack, NH.

Manchester reaches its last hard frost near late-May; that is the cue for kale, peas, spinach, and parsnips. Manchester's heat-lovers — tomatoes, peppers, squash — hold off until Manchester's frost risk clears, 10-14 days on. By early-October, frost is back in Manchester — protect or harvest anything tender. A creek-bottom lot in Manchester can lag Manchester's last frost 7-10 days behind a south slope.

Similar climates: South Hooksett, NH, Pinardville, NH, East Merrimack, NH, Klondike Corner, NH, Suncook, NH.
