Paris police authorities requested the cancellation of the Diamond League track and field meeting, scheduled for June 28, 2026, on June 24, 2026. The police also requested the cancellation of other events planned for the weekend of June 27-28, 2026, including a music festival and a Pride march.

The Paris police prefecture stated it would enforce a cancellation order if organizers did not agree to cancel voluntarily. This action was taken due to exceptional heat affecting Paris since June 21, 2026, and the need for emergency services to concentrate efforts on protecting vulnerable people.

Organizers released a statement on June 25, 2026, indicating their plan to proceed with the track and field meet in an adapted format. "The safety of athletes, coaches, volunteers, officials and spectators remains our absolute priority," organizers stated. "As a result, only elite athletes will be permitted to compete at the Paris Meeting, in accordance with this exemption." Organizers added, "This adaptation ensures that the event can proceed while maintaining the highest possible standards of safety."

As of June 26, 2026, the French track and field federation had not yet received a cancellation order from the police. Athletes expected to compete in the Paris Diamond League meet included Noah Lyles, Femke Bol, and Mondo Duplantis.

On June 25, 2026, the average temperature recorded across 30 weather stations by Meteo France was 30 degrees C (86 F). This temperature matched the record for the hottest day nationwide, set on June 24, 2026. More than 75 percent of France was under a red weather alert on June 25, 2026.
