Ottawa kids traded pool days for pencil cases this week as thousands of students across the city headed back to class on a first day marked by thick, sticky humidity. For a lot of families, the return to school routine, uniforms ironed, lunches packed, alarms reset, came with an extra layer of discomfort as humidex values pushed the mercury well past what feels comfortable in a crowded classroom.
A Sweaty Start to the School Year
Across Ottawa Carleton District School Board (OCDSB) and Ottawa Catholic School Board schools, students and staff filed into buildings that, in many cases, are decades old and were never built with air conditioning in mind. Older schools in neighbourhoods like Old Ottawa South, Vanier, and parts of the west end can turn into greenhouses by early afternoon when humidity spikes, and this week's conditions were no exception.
Teachers reported propping open windows and doors where possible, and some classrooms brought out portable fans to keep air moving. For younger students especially, the combination of new-year nerves and sticky heat made for a long first day.
Why This Matters for Ottawa Families
Ottawa's school infrastructure has been a recurring talking point at board meetings, with both the OCDSB and the Ottawa Catholic School Board fielding questions from parents about cooling upgrades in aging buildings. While newer schools in growing suburbs like Barrhaven and Kanata tend to have better climate control, some of the city's older core schools still rely largely on open windows and box fans during hot spells.
That gap has real consequences on days like this one. Parents on Ottawa parenting forums and social media groups were quick to compare notes on which schools felt unbearable by mid-morning, with several noting that gym classes and recess were shortened or moved indoors to limit exposure to the heat.
What Parents Can Do
Pediatric health guidance for humid days is fairly consistent: send kids in light, breathable clothing, pack an extra water bottle, and keep an eye out for signs of overheating like flushed skin, headaches, or unusual fatigue after school. Both Ottawa school boards typically leave water bottle policies flexible on hot days, and many schools encourage refilling from water fountains or bottle-filling stations throughout the day.
For families whose kids attend older schools without air conditioning, it's worth checking in with teachers about how the classroom is managing the heat, especially in the first few weeks of September, which can still bring humidex-driven swelter even as fall officially approaches.
The Bigger Picture
The muggy start adds to an ongoing conversation in Ottawa about aging school infrastructure and climate resilience. As summers trend warmer and more humid, the pressure on school boards to invest in cooling systems for older buildings isn't going away. For now, Ottawa's students and teachers are doing what they can: open windows, extra water breaks, and a bit of patience as everyone settles back into the rhythm of the school year.
