The state’s biggest districts, each read against its own forecast and its own big snow morning.
New Hampshire requires 180 days or the required hours: 450 in kindergarten, 945 in grades 1 to 6 and 990 in grades 7 to 12.
“The school board of every district shall provide standard schools for at least 180 days in each year, or the equivalent number of hours as required in the rules of the department of education”
Lost time must be rescheduled with added hours before a district can ask for a waiver of the hours requirement.
“Schools shall use additional hours to reschedule lost instructional time before requesting a waiver of the amount of instructional time under RSA 189:2.”
Remote learning counts toward the required instructional time when bad weather makes it unsafe to transport students, with no cap stated in the rule.
“Remote learning shall satisfy the requirements of RSA 189:1 and RSA 189:24 under the following conditions: (1) When inclement weather makes it unsafe to safely transport students to or from in-person instruction;”
Kindergarten sessions canceled by a delayed opening or early release for older grades do not have to be made up; the rule says nothing about whether a delayed day counts for grades 1 to 12.
“There shall be no requirement to reschedule instructional time for kindergarten if morning or afternoon kindergarten sessions are cancelled due to delayed opening or early release for students in grade 1 or higher.”
Ranked by weekday mornings from December through March with 4 inches or more of new snow at the 7 am reading, averaged over ten winters at each district’s nearest NOAA weather station.
How many snow days New Hampshire districts plan for
8 New Hampshire districts print a number of snow days on their own 2026 to 2027 calendars. A closing inside that number leaves the calendar as printed; one past it is made up, usually from a break or the end of the year.
Snow a winter and 4 inch mornings come from each district’s nearest NOAA weather station over ten winters. Built in days are the district’s own, read from its calendar. Every linked district has a page with its live odds, its snow record and its schools.

All 176 in the state, by ZIP, with a page of their own for 50, including Manchester, Nashua and Bedford. Every page carries the district’s own snow record and the odds for its next three school mornings.
A typical New Hampshire district sees about 6.9 weekday mornings a winter with 2 inches of new snow or more, and 3.3 with 4 inches or more, counted on weekdays from December 1 through March 31 at each district’s nearest NOAA weather station over ten winters. The snowiest districts in the table see several times that.
Three school mornings, as far as the National Weather Service hourly forecast reaches. Weekends and the district’s winter break are skipped, so a Friday storm is read for Monday’s buses.
It reads the National Weather Service forecast for your ZIP through the night and the bus hours, adds winter alerts and the Winter Storm Severity Index, and measures the snow against what counts as a big morning for your district. The state rules come from the New Hampshire Department of Education and the state code.
