Best Time to Go Rafting in Calgary During a Heat Wave
When Calgary hits a stretch of hot, sunny days, the instinct is to find water, and the Bow River happens to be one of the best ways to do exactly that. With warm weather driving a noticeable jump in interest in rafting this summer, here’s why a heat wave is actually the ideal time to book a trip, what to expect, and how to prepare.
Why Hot Weather Is Perfect Rafting Weather
It might seem counterintuitive, but the hotter the day, the better a rafting trip tends to feel. The Bow River stays consistently cool even during a heat wave, since it’s fed by mountain snowmelt and glacier runoff rather than warming up with the air temperature. That means guests get the full benefit of the sun overhead while staying refreshed on the water, a natural way to beat the heat that many indoor activities simply can’t match.
What Makes This Different from a Regular Summer Day
On a typical warm day, rafting is a fun outdoor outing. During an actual heat wave, it becomes one of the more comfortable ways to spend an afternoon outside in Calgary at all; guests are on the water, not standing on hot pavement, and the splash factor that’s a highlight any day becomes a genuine relief when it’s 30-plus degrees.
What to Expect on a Hot-Weather Trip
The trip itself runs the same as any other day: a safety briefing, a scenic and playful run down the Bow River, and a shuttle back at the end. The only real differences are what you’ll want to bring and what you’ll want to wear, covered below.
What to Wear and Bring When It’s Hot Out
A few small adjustments make a hot-weather trip more comfortable:
- Quick-dry clothing and secured footwear (water shoes or sandals with a back strap) rather than cotton, which stays wet and heavy
- Reef-safe sunscreen, reapplied after getting splashed; regular sunscreen can wash off quickly in the water
- Skip packing your own cooler, our boxed lunches to go are ready when you are
- A hat with a chin strap or clip so it doesn’t blow or float away
- A refillable water bottle; staying hydrated matters even more on a hot day, on or off the water
- Sunglasses with a strap, since the glare off the water is stronger than most guests expect
For general heat-warning safety tips beyond the trip itself, the City of Calgary’s guidance on what to do during extreme heat is a good resource to check before you head out.
Is the Bow River Cold Even in Hot Weather?
Yes, the Bow River’s source in glaciers and snowmelt keeps it noticeably cooler than the air temperature, even at the height of summer. Guests should expect the water to feel cold on contact, even on a scorching day on land, which is part of what makes the trip such an effective way to cool down.
More Ways to Beat the Heat with Lazy Day
A rafting trip pairs naturally with the rest of what Lazy Day Wellness offers if you’re looking to make a full day of it; a Floating Sound Bath session later in the evening is a cool, calm way to close out a hot day on the water. If you’d rather combine activities, our Bike and Raft Experience pairs a scenic ride with a float, or rent an e-bike on its own to explore more of the city.
