2026 Final Stefanos Tsitsipas defeated Raphaël Collignon 6–4, 6–7(3), 6–3 to claim the Swiss Open Gstaad title — his first ATP Tour title on clay in over two years and one of the most significant results of his comeback season. Collignon, a Belgian qualifier ranked outside the top 100, put up a fierce battle in the second set before Tsitsipas closed out the match in three sets.
Altitude Gstaad sits at approximately 1,050 meters (3,445 feet) above sea level in the Bernese Oberland region of the Swiss Alps, making it the highest-altitude clay-court tournament on the ATP calendar. At this elevation, the air is noticeably thinner, causing the ball to travel faster and bounce higher than at sea-level clay events. The effect is more pronounced here than at Madrid — the only other high-altitude clay stop on tour — and significantly changes the character of the surface, giving big hitters and heavy topspin players a distinct advantage over defensive grinders.
Humidity July in Gstaad brings cool Alpine summer conditions, with average temperatures between 8°C and 20°C (46°F–68°F) during tournament week — significantly cooler than any other clay event on the calendar. Humidity varies considerably due to the mountain environment, and afternoon thunderstorms rolling in from the Alps are common, frequently interrupting play and requiring rapid court preparation between showers. Morning mist and cool temperatures can also slow the courts early in the day before the mountain sun dries them out.
Outdoor Tournament The Swiss Open Gstaad is played outdoors at the Roy Emerson Arena, a unique open-air venue nestled in an Alpine valley and surrounded by mountain scenery. Named after the legendary Australian champion Roy Emerson, who was closely associated with the tournament, the venue has an intimate, festive atmosphere unlike anything else on the ATP Tour — with cowbells, mountain air, and the backdrop of the Bernese Alps creating one of the most picturesque settings in professional tennis.
Surface Despite being red clay, the combination of high altitude and cool Alpine temperatures makes Gstaad play noticeably faster than typical clay events. The thinner air at over 1,000 meters allows groundstrokes to carry further and serves to zip through with extra pace, while the cooler temperatures keep the clay from becoming too heavy or sticky. The result is a surface that sits between traditional clay and a medium-fast court — rewarding aggressive play and heavy topspin far more than defensive retrieval.
