Temperatures at the French Open have surged to 33°C (91°F), creating conditions hotter than players remember at Roland Garros. The clay courts are playing faster than usual, fundamentally changing match dynamics during the opening rounds.

Four-time champion Iga Swiatek routed Emerson Jones 6-1, 6-2, while Daria Kasatkina defeated Zeynep Sonmez 6-4, 6-4. Alex de Minaur beat Toby Samuel 6-4, 6-4, 6-2, and Alex Michelsen eliminated Alexandr Shevchenko in straight sets. Players are using ice bags on changeovers and fans crowd under sprinklers for relief.

The 91-degree heat accelerates ball speed through the air, favoring aggressive baseliners. De Minaur noted the faster conditions let him play more offensively without heavy spin. Kasatkina observed that focus drops unexpectedly in the energy-sapping environment, making adaptation crucial for survival.

French Open organizers have not clarified whether a heat protocol exists, unlike the Australian Open's strict intervention thresholds. The unseasonable May heat transforms the typically cool clay tournament into a physical battle where conditioning and tactical adjustments determine who advances.
