Aberdeen School District 06-1 Snow Day Predictor

Q: When is the last day of school for Aberdeen?

May 17, 2027, on the district’s 2026 to 2027 calendar.

Q: How much snow does Aberdeen get?

About 33.2 inches a winter at a NOAA weather station under a mile away, averaged over 9 winters. Between December 1 and March 31 that brings 3.6 weekday mornings a year with 2 inches of new snow or more, and 1.3 with 4 inches or more.

Q: What was the biggest snow day near Aberdeen?

9 inches on April 1, 2023, the largest single day at a NOAA weather station under a mile away in 9 winters. The snowiest winter was 2018 to 2019, with 69.1 inches.

Q: How does the Aberdeen snow day predictor work?

It reads the National Weather Service forecast for Aberdeen 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 Aberdeen’s own big snow morning: 4 inches, the top tenth of snowy weekday mornings at a NOAA weather station under a mile away.

The South Dakota rule

How South Dakota counts a lost day

South Dakota requires at least 437.5 hours for kindergarten, 875 hours for grades 1 to 5 and 962.5 hours for grades 6 to 12; the local board sets the number of days. The Secretary of Education may waive the minimum hours when the Governor or the President declares a state of emergency covering the school; there is no fixed count of forgiven days.
