2026 Final Learner Tien defeated Mariano Navone 3–6, 6–3, 7–5, claiming his first ATP clay-court title and second career title overall.
Altitude Geneva sits at approximately 375 meters (1,230 feet) above sea level, nestled between the Alps and the Jura mountains on the shores of Lake Geneva. This moderate elevation is noticeably higher than Paris or Rome, giving the ball a slightly extra speed through the air compared to sea-level clay events. The effect is subtle but real — serves carry a bit more pace and groundstrokes zip through the court fractionally faster than at Roland Garros a week later.
Humidity May in Geneva brings mild spring temperatures between 10°C and 18°C (50°F–66°F), with humidity typically ranging from 65–75%. The proximity to Lake Geneva adds extra moisture to the air, which keeps the clay courts heavy and slow despite the moderate altitude. The lake effect can also bring sudden weather changes, with cool breezes or afternoon showers disrupting the schedule during tournament week.
Outdoor Tournament Played outdoors at the Parc des Eaux-Vives on the shores of Lake Geneva, the venue is one of the most scenic on the entire ATP calendar.
Surface Despite the moderate altitude, the combination of lake humidity and traditional red clay preparation makes Geneva play slower than its elevation might suggest. The heavy, high-bouncing conditions strongly favor baseline grinders and topspin specialists. Geneva serves as one of the final clay tune-ups before Roland Garros, and its conditions closely mirror what players will face in Paris the following week.
