Janesville School District Snow Day Predictor
The odds of a closing or a delay on the next three school mornings in Janesville, measured against Janesville's own big snow morning of 3.6 inches.
Will Janesville close tomorrow?
How Janesville calls a snow day
When the call comes
The night before (if possible) or by 6:00 a.m.
“information will be communicated to the public the night before (if possible) or by 6:00 a.m. on the day of the closing or delay.”Source
How families hear
By email, phone call, text message, the district website, social media and local TV.
“You can choose to receive messages via any/or all inbox, email, voice, and/or text options.”School Closings & Delays - School District of Janesville
A 2 hour delay
On a delay morning every school starts 2 hours late.
“If the SDJ decides a 2-hour delay is needed, middle and high school classes will begin at 10:00 AM, with elementary school starting at 10:15 AM. On delay days, school breakfast will not be available, but school lunches will.”Delay schedule
2 built in snow days
On the 2026 to 2027 calendar, listed as “inclement weather days ('snow days')”.
“The SDJ school calendar has built-in time to accommodate weather delays/closures. With that in mind, the SDJ will allow for two inclement weather days to be just that – 'snow days' on which no school work will be required of students.”Source
Making up a lost day
Beyond the first two days, the district announces a plan for any missed hours.
“With any additional inclement-weather days beyond the first two, the SDJ will communicate plans to address any missed instructional hours that may need to be made up.”Source
