Westwood School District Snow Day Predictor

Q: How much snow does Westwood get?

About 41.3 inches a winter at a NOAA weather station 1.3 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 3.7 weekday mornings a year with 2 inches of new snow or more, and 1.8 with 4 inches or more.

Q: What was the biggest snow day near Westwood?

16.8 inches on January 26, 2026, the largest single day at a NOAA weather station 1.3 miles away in 10 winters. The snowiest winter was 2017 to 2018, with 68 inches.

Q: How does the Westwood snow day predictor work?

It reads the National Weather Service forecast for Westwood through the night and the 5 to 8 am bus run, adds winter alerts and the Winter Storm Severity Index, and measures the snow against Westwood’s own big snow morning: 5.7 inches, the top tenth of snowy weekday mornings at a NOAA weather station 1.3 miles away.

Q: How far ahead does the Westwood snow day predictor look?

Three school mornings, as far as the National Weather Service hourly forecast reaches. Weekends and breaks are skipped, so a Friday storm is read for Monday’s buses.

The odds of a closing or a delay on the next three school mornings in Westwood, measured against Westwood's own big snow morning of 5.7 inches.

The Massachusetts rule

How Massachusetts counts a lost day

Massachusetts requires a 185 day calendar, at least 180 days actually held, and 900 hours for elementary or 990 hours for secondary students. Every day lost through March 31 is made up with full rescheduled days; after March 31, days are made up until 180 or the scheduled 185th day, whichever comes first.

The Massachusetts rules in the agency’s own words, and every Massachusetts district
