Peterborough Snow Day Predictor & Calculator
Will KPRDSB close tomorrow?
The Kawartha Pine Ridge District School Board covers one of the largest geographic footprints in Ontario — Peterborough, Cobourg, Lindsay, Port Hope, Kawartha Lakes, and all of Northumberland and Peterborough counties. When KPRDSB closes, all 80 schools across this entire region close simultaneously. Rural route conditions across Kawartha Lakes and Northumberland County — not Peterborough city streets — drive the closure decision.
Peterborough receives 180 to 210cm of snow annually from Alberta clipper systems and nor'easters tracking up the St. Lawrence valley. KPRDSB closes 7 to 10 times per year — significantly more than GTA boards because rural county roads in the board's coverage area receive lower plowing priority and deteriorate faster during winter storms.
KPRDSB Announcement Window

Check at 9pm for an early read and again at 5am for the final pre-announcement probability. KPRDSB announces by 6:00 AM — covers Peterborough, Cobourg, Lindsay, and all of Northumberland County.
Peterborough School Boards — KPRDSB & PVNCCDSB
Two school boards serve Peterborough and the Kawarthas — both almost always align on closure decisions.
Kawartha Pine Ridge District School Board
KPRDSB covers Peterborough, Cobourg, Lindsay, Port Hope, Kawartha Lakes, and all of Northumberland and Peterborough counties — 80 schools across a vast geographic area. Rural Kawartha Lakes and Northumberland County route conditions drive the closure threshold.
Peterborough Victoria Northumberland and Clarington CDSB
PVNCCDSB almost always aligns with KPRDSB — both boards monitor the same road conditions. Always verify at pvnccdsb.on.ca or @PVNCCDSB directly.
KPRDSB covers all of the Kawarthas and Northumberland: If you live in Cobourg, Lindsay, Port Hope, Norwood, Havelock, or surrounding communities — this snow day predictor applies to your school. All 80 KPRDSB schools close simultaneously when a closure is called.

KPRDSB Snow Day Predictor — Cobourg, Lindsay & Kawartha Lakes
KPRDSB covers the entire Kawarthas and Northumberland County. One predictor serves all communities.
Cobourg Snow Day Predictor
Cobourg and all of Northumberland County fall under KPRDSB. Located on Lake Ontario, Cobourg can receive lake-effect snow from Lake Ontario in addition to regional systems. When KPRDSB closes, Cobourg schools close simultaneously with Peterborough. Use this predictor for Cobourg school closures.
Lindsay Snow Day Predictor
Lindsay and all of City of Kawartha Lakes fall under KPRDSB. Rural Kawartha Lakes routes between Lindsay and surrounding townships are among the most vulnerable to winter conditions in the board's coverage area. When KPRDSB closes, Lindsay schools close simultaneously.
Port Hope & Northumberland
Port Hope and Northumberland County fall under KPRDSB. Rural Northumberland County routes between Cobourg, Port Hope, and Campbellford are frequently the first to be declared unsafe and often drive the board-wide closure decision for all 80 schools.
One predictor covers all of KPRDSB territory: Whether you are in Peterborough, Cobourg, Lindsay, Port Hope, or anywhere in Northumberland or Kawartha Lakes — snowdayprediction.ca Peterborough Snow Day Predictor applies to your school. KPRDSB makes one decision for all 80 schools.
Peterborough Snow Day Patterns
Why KPRDSB closes more than GTA boards despite Peterborough's moderate location.
Primary Snow Source — Alberta Clippers
Alberta clipper systems tracking northeast across Ontario are Peterborough's primary snowfall source — producing consistent 10 to 20cm events multiple times per winter. Clippers move fast and can deposit significant snowfall overnight, creating the morning conditions that trigger KPRDSB closures. The speed of clipper systems means road conditions can deteriorate faster than plows can respond.
Secondary Source — Nor'easters
Nor'easter systems tracking up the St. Lawrence valley bring heavy snowfall from the east to Peterborough and Northumberland County. Nor'easters produce the largest single-storm snowfall events for the Peterborough region — 25 to 40cm events that exceed what Alberta clippers produce. Cobourg and Port Hope on Lake Ontario often receive heavier accumulation than Peterborough city during nor'easter events.
Rural Routes Drive Closures
KPRDSB's 80 schools span a territory that includes long rural bus routes through Kawartha Lakes and Northumberland County. These county roads receive lower plowing priority than Highway 115 or Peterborough city streets. A storm that leaves Peterborough manageable can make the rural routes between Lindsay, Norwood, Havelock, and Campbellford impassable. KPRDSB closes for the worst route, not the average city condition.
Peterborough vs Ontario — Closure Comparison
KPRDSB averages 7 to 10 school closure days per year — more than Toronto (3 to 5) but fewer than Barrie (12 to 15) and Sudbury (12 to 15). Peterborough sits in the middle tier of Ontario closure frequency — more than GTA boards due to rural footprint, less than northern boards due to lower total snowfall.
What to watch for in Peterborough: Overnight forecasts showing 15cm+ of snowfall are the primary KPRDSB closure signal. Nor'easter warnings covering Northumberland County are a strong indicator for Cobourg and Port Hope. If the forecast shows heavier accumulation toward Kawartha Lakes or Northumberland while Peterborough looks marginal, prepare for a closure — rural route conditions drive the decision. Check snowdayprediction.ca at 9pm and again at 5am.
Peterborough KPRDSB Snow Day History
Historical KPRDSB closure data — what storms actually closed Peterborough schools and why.
Notable KPRDSB Closure Events
Alberta clipper deposited 25cm across Peterborough and Northumberland County in 24 hours. KPRDSB closed all 80 schools. Highway 115 north of Peterborough declared unsafe. Rural Kawartha Lakes routes impassable by 3am.
Nor'easter deposited 30cm across Peterborough and Northumberland County. KPRDSB closed. One of the largest nor'easter events for the Peterborough region in five years. Cobourg and Port Hope particularly hard hit.
Arctic outbreak with wind chill reaching -38°C across Peterborough and Kawartha Lakes. KPRDSB closed for cold-day safety despite minimal snowfall. Rural Northumberland County roads declared unsafe by 4am.
Worst Peterborough winters on record for school closures
2007–2008 · 2014–2015 · 2021–2022 — these winters produced the highest number of KPRDSB closure events, with 2014–2015 notable for both heavy Alberta clipper events and multiple nor'easter systems that hit Northumberland County hard.
Peterborough Road Conditions
Highway 115 · Highway 7 · Northumberland County Roads · Kawartha Lakes County Roads
Highway 115 north of Peterborough, Highway 7 east toward Norwood and Havelock, and rural Northumberland County and Kawartha Lakes roads are the key corridors monitored by KPRST and KPRDSB assessors. When these routes show ice or closure warnings on 511on.ca alongside a KPRST cancellation, a full KPRDSB school closure is very likely.

Peterborough Snow Day Tips for Parents
KPRDSB-specific advice based on how Kawartha Lakes school closures actually work.
Watch Nor'easter Forecasts for Northumberland
Cobourg, Port Hope, and Northumberland County often receive heavier snowfall than Peterborough city during nor'easter events. If the forecast shows significant accumulation along the Lake Ontario shoreline, prepare for a KPRDSB closure — Northumberland County rural routes drive the board-wide decision just as much as Peterborough city conditions.
Rural Routes Close Before City Streets
Peterborough city streets may look manageable while rural Kawartha Lakes and Northumberland county routes are dangerous. KPRDSB closes for the worst route across all 80 schools — do not look out your Peterborough window and assume school is open. Always check kprschools.ca or @KPRSchools directly.
The River 93.7 FM Is the Fastest Local Source
The River 93.7 FM and CBC Radio One 90.5 FM receive KPRDSB notifications simultaneously with the board website. Radio announcements often reach Peterborough families faster than website checks during high-traffic storm mornings.
Check at 9pm and 5am
The 9pm check gives you the best early read to arrange backup childcare. The 5am check — just before KPRST and KPRDSB assessors report in from Kawartha Lakes and Northumberland routes — gives you the most accurate pre-announcement read. KPRDSB announces by 6:00 AM.

Why do Peterborough schools sometimes close when city roads look fine?
KPRDSB covers rural Northumberland County and Kawartha Lakes where roads receive lower plowing priority. A storm that leaves Peterborough city streets manageable can make rural county roads between Lindsay, Cobourg, and Port Hope impassable. KPRDSB makes one closure decision for all 80 schools — rural route conditions, not Peterborough city streets, set the threshold.
What triggers a KPRDSB school closure?
Overnight snowfall above 15cm and rural route conditions in Northumberland County and Kawartha Lakes are the primary triggers. When KPRST cancels buses region-wide, KPRDSB almost always closes all schools. Freezing rain warnings also trigger closures — rural Northumberland County roads ice faster than Peterborough city streets.
