Whether you’re a student hoping for a day off or a parent planning ahead, this article will give you all the insights you need about Boston’s winter weather predictions.
What Is the Boston Snow Day Calculator?
The Boston Snow Day Calculator is an online tool designed to predict the probability of school closures based on upcoming weather forecasts. Created by a student (later popularized by meteorologists), this calculator uses historical data, current weather predictions, and regional school district policies to estimate whether schools will shut down due to snow.
How Does the Calculator Work?
The tool analyzes several key factors:
-
Expected Snowfall Amount – The more snow predicted, the higher the chance of closures.
-
Timing of the Storm – Snowstorms overnight or early morning increase cancellation odds.
-
Temperature & Wind Chill – Extreme cold may lead to closures even with less snow.
-
Road Conditions – Icy or untreated roads make transportation unsafe.
-
School District Policies – Some districts cancel school more easily than others.
By inputting weather data, the calculator generates a percentage likelihood of a snow day.
Factors That Influence Boston Snow Day Predictions
1. Historical Snowfall Trends
Boston averages about 49 inches of snow per year, but some winters bring much more. The infamous 2014-2015 season saw over 110 inches, leading to frequent school closures.
2. Storm Severity and Timing
-
Nor’easters (powerful East Coast storms) often cause major disruptions.
-
If snow starts before dawn, plows may not clear roads in time for school buses.
3. Temperature and Wind Chill
Even if snowfall is light, subzero temperatures and dangerous wind chills can force closures.
4. School District Decisions
-
Boston Public Schools (BPS) tend to be cautious, often closing with 6+ inches of snow.
-
Surrounding suburbs (e.g., Newton, Cambridge) may have different thresholds.
5. Remote Learning Policies
Since the pandemic, some schools opt for virtual learning instead of full cancellations.
How Accurate Is the Boston Snow Day Calculator?
While the calculator is a fun and useful tool, its accuracy depends on:
-
Weather forecast reliability (predictions can change last-minute)
-
Local government response (how quickly roads are plowed)
-
School superintendent’s discretion (some are more conservative than others)

-
