Roland Garros Sets First Grand Slam Hard Heat Limit at 32.2°C

The French Tennis Federation has established a wet bulb globe temperature ceiling of 32.2°C at which play suspends across all Roland Garros courts. The threshold makes the French Open the first Grand Slam to institute a hard temperature floor for competition safety. The FFT monitors conditions via on-site thermometers that measure ambient temperature, humidity, radiant heat, and wind. When WBGT reaches 30.1°C, players can request one 10-minute break before a potential deciding set. No match has been called off under current protocols.
