World Cup Heat Watch: One Stadium Hits 98% Heat Risk Today

Today's World Cup matches bring more than just knockout-round pressure. New data shows that all three June 30, 2026 games carry a chance of "performance-impairing heat," with one venue logging a 98% risk as a heat dome continues to grip much of North America.

Climate Central defines performance-impairing heat as temperatures above 82.4°F. Research has linked those conditions to elite soccer players running slower, covering less distance, and completing fewer high-intensity sprints. For fans in open-air venues or spending extended time outdoors, the same heat poses real health risks.

Highest Heat Risk: Ivory Coast vs. Norway

The Ivory Coast vs. Norway match at Dallas Stadium tops today's heat risk chart at 98%, with climate change adding 2% to that figure.
