The state’s biggest districts, each read against its own forecast and its own big snow morning.
When a board extends the calendar to make up weather closures, it may excuse seniors who have already met graduation requirements.
“If the board of directors of a district or the authorities in charge of an accredited nonpublic school extends the school calendar because inclement weather caused the school district or accredited nonpublic school to temporarily close”
No more than 5 days or 30 hours of the required instruction may be delivered mainly online, unless another section or State Board rule allows more.
“of which not more than five days or thirty hours of instruction may be delivered primarily over the internet except as otherwise provided in section 256.43 or in rules adopted by the state board of education pursuant to section 256.7, subsection 32.”
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.
3 Iowa 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.

Questions
Iowa snow day questions
Iowa requires at least 180 days or 1,080 hours of instruction, as the board chooses.
When a board extends the calendar to make up weather closures, it may excuse seniors who have already met graduation requirements.
No more than 5 days or 30 hours of the required instruction may be delivered mainly online, unless another section or State Board rule allows more.
All 323 in the state, by ZIP, with a page of their own for 34, including Des Moines, Cedar Rapids and Iowa City. Every page carries the district’s own snow record and the odds for its next three school mornings.
A typical Iowa district sees about 3.1 weekday mornings a winter with 2 inches of new snow or more, and 1.1 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 Iowa Department of Education and the state code.
