Shinnecock Hills Golf Club, set to host the U.S. Open in 2026, has a history of providing one of golf's most challenging tests, often bordering on controversial. Past U.S. Opens at Shinnecock in 2004 and 2018 drew significant criticism for course conditions. In 2004, the seventh green became so unplayable that it required mid-round watering. Similarly, the 2018 tournament saw winner Brooks Koepka score one-over-par, with players openly expressing frustration about the setup, characterized by narrow fairways, five-inch rough, and rock-hard greens exacerbated by coastal winds.

The USGA acknowledges past issues, with John Bodenhamer, responsible for course setup, admitting that playing conditions in 2004 and 2018 were "sub-optimal." He has indicated that lessons were learned and that there will be some differences in 2026, including wider fairways to align more with original designer William Flynn's philosophies. However, Shinnecock's inherent design, lacking trees to shield from coastal winds, and its naturally firm, fast, and undulating greens, make it particularly susceptible to extreme conditions.

Despite the USGA's attempts to find a balance, the course's natural elements, especially wind, are major factors. Players like Rory McIlroy praise Shinnecock as a comprehensive test of golf, but note how crucial understanding wind direction and speed is. Even with intentions to make greens softer than in past contentious tournaments, the wind can quickly dry out any moisture, making greens notoriously hard to hold. The delicate balance results in a course where small adjustments in setup, combined with weather, can quickly shift the narrative from a challenging test to an unfairly punitive one, making it a demanding venue to manage for U.S. Open organizers.
