WBGT Warning Looms Over Roland Garros as Heat Rises
The French Open is confronting dangerous heat, with officials using the wet bulb globe temperature (WBGT)—a metric that combines temperature, humidity, solar radiation, and wind—to gauge risk and justify shade breaks, cooling, and potential delays. While elite athletes can tolerate higher heat, WBGT thresholds around the mid-80s°F mark signal growing health risks, and scientists warn that climate trends could push these extreme conditions into the norm in hot regions.
