The Korean Baseball Organization cancelled all scheduled games through Sunday, Aug. 8, following an extreme heat wave across South Korea [1, 2].
The league's decision highlights the growing danger of climate extremes on professional athletes and fans, as rising temperatures create hazardous conditions in stadiums. The move comes after a surge in heat-related illnesses among players and spectators [1, 2].
KBO Secretary General Park Geun-chan said that while there is inevitable pressure regarding the remaining game schedule, the safety of the spectators and the players must be the top priority [1].
Officials reported that ground temperatures on artificial turf reached up to 70°C [1]. This extreme heat posed a direct risk to players' health and safety during active play.
Games are scheduled to resume on Tuesday, Aug. 9 [2]. To mitigate future risks, the KBO, the professional baseball players’ association, and 10 team presidents agreed to several operational changes. All resuming games will now have a shifted start time of 19:00 [2].
Additionally, the league will introduce a four-minute "cooling time" break [2]. These mandatory breaks will be inserted after the third, fifth, and ninth innings to allow players and staff to recover from the heat [2].
These measures represent a significant shift in how the league manages player welfare during the summer months. The KBO said that the health of the participants is the primary driver for these new protocols [1].
“Ground temperatures on artificial turf reached up to 70°C.”
The KBO's decision to halt play and permanently alter game structures suggests that traditional sports schedules are becoming incompatible with extreme weather patterns in East Asia. By implementing structural changes like 'cooling times' and later start times, the league is acknowledging that temporary cancellations are insufficient and that long-term adaptation to higher peak temperatures is necessary for player safety.
