Beach volleyball is a popular sport that is played recreationally and professionally across the country. Courts are usually found on local beaches and in indoor and outdoor facilities. The sport has gained momentum in Canada, especially since Canada won the silver medal in women’s beach volleyball at the 2024 Paris Olympics [1]. Montreal hosts the annual Volleyball World Beach Pro Tour, a competition that attracts spectators from all over the world.
However, like many outdoor sports, beach volleyball is increasingly feeling the effects of our changing climate. Rising temperatures, extreme weather events, wildfire smoke, and coastal erosion are reshaping beaches across Canada, while also posing growing risks to the health and safety of the athletes and spectators who gather to play and watch. Elite athletes are beginning to discuss the impacts that they are experiencing as temperatures continue to rise, with one Olympian speaking out (Melissa Humana-Paredes) after temperatures at the 2025 Montreal Beach Pro Tour soared above 30°C. As beach volleyball continues to gain popularity, now is the time to examine how climate change is affecting the sport and how we can protect the beaches, players, and fans that make it possible.
“[At the Tokyo Olympics] we saw sports changing venues or times because it was too hot. For the marathon, they had to change location. For the women’s soccer gold medal match, they changed the time from day to night. These are things we never heard of before.”

Professional events like the Montreal Beach Pro Tour attract world-class players and hundreds of fans every August to Parc Jean-Drapeau, just south of the city of Montreal. This region, like almost all regions across southern Canada, is expected to experience a large increase in extremely hot, potentially dangerous summer days.
Hot air temperatures have many direct health impacts, such as heat exhaustion and heat stroke. Higher air temperatures can also lead to higher sand temperatures, though factors like cloud cover, relative humidity, and shade can mitigate or amplify the effects. High sand surface temperatures can lead to first-, second-, and even third-degree burns in rare cases. Beach volleyball players spend hours diving, sprinting, and jumping barefoot on hot sand, making this a safety issue that could cut games short or sideline players due to injury.
When air temperatures are relatively moderate (e.g., 24°C (75°F)), sand temperatures can reach 38°C (100°F) in direct sunlight. When air temperatures reach 32°C (90°F), however, sand temperatures can reach over 49°C (120°F) [2] (Figure 1). Skin begins to burn when surface temperatures reach 44°C (111°F) [2].
Focusing on Montreal, home of the Beach Pro Tour in Canada, Table 1 compares the historical and projected future frequency of days with air temperatures above 29°C, which can correspond to sand temperatures of approximately 44°C or higher. This threshold was selected because it represents conditions where hot sand may pose a burn risk to barefoot athletes. For context, the table also includes an indicator of conditions that may meet Environment and Climate Change Canada’s extreme heat warning criteria, allowing for a comparison between potential sand heat risks and broader heat-related health risks.

| Annual Historical Average (1971–2000; median) | Annual Future Projection Average (2021–2050; median) | Annual Future Projection Average (2051–2080; median) | |||||||
| Heat Variable | SSP2-4.5 | SSP3-7.0 | SSP5-8.5 | SSP2-4.5 | SSP3-7.0 | SSP5-8.5 | SSP2-4.5 | SSP3-7.0 | SSP5-8.5 |
| Local Heat Warning potential* (Days with Humidex >40°C**) | 1 | ** | 1 | 5 | ** | 6 | 10 | ** | 22 |
| Potential Days with Sand Temperature >44°C (air temperature >29°C)*** | 16 | 16 | 16 | 37 | 38 | 39 | 49 | 58 | 67 |
* In Montréal, heat warnings issued by Environment and Climate Change Canada are triggered when temperatures of at least 30°C combined with a humidex of 40 or higher are expected to last for at least one hour (or when temperatures reach 40°C or higher). Therefore, the number of projected days with a humidex above 40 should be interpreted as an indicator of extreme heat potential, not a direct count of future heat warning days.
** Humidex values are not available for SSP3-7.0.
*** Calculated by assuming sand temperature = air temperature + 15°C based on Cohen (2019). Actual sand temperatures can vary depending on shade, cloud cover and moisture. This is intended as an illustration of potential sand heat risk.
Table 1 shows that, under all emissions scenarios, by 2021-2050, Montreal could experience 37-39 days where sand temperatures are potentially dangerous (21 to 23 more days than Montreal has experienced in the past), and by 2051-2080, this number could jump to 49 to 67 days (33 to 51 more days than historically).

Box 1: Heat risks and open-air stadiums
Not only is heat a concern for the beach volleyball players but also for the audience. Most professional beach volleyball events take place in open-air arenas or stadiums, like the Montreal Beach Pro Tour, where spectators are also at risk of rising temperatures. Temperatures inside open-air stadiums can be much higher than surrounding environments and weather station readings, due to large crowds and greater absorption of radiation from the sun
