Golfers at the 154th Open Championship at Royal Birkdale are anticipating "unprecedented" conditions, described as firm and fast, a stark contrast to the wet 2017 Open won by Jordan Spieth. World No. 1 Scottie Scheffler noted the need for strategy and thinking on each hole, comparing the course to the 2022 Open at St. Andrews but emphasizing Royal Birkdale's narrower fairways and mounding.

Temperatures have been unseasonably warm with little rain forecast, leading to dry conditions that may affect the rough. Jon Rahm predicted that winds off the Irish Sea could lead to unusually long drives, calling the situation "unprecedented." Rory McIlroy and Justin Rose suggested these conditions might even offer opportunities for aggressive play, with the rough burning out.

The firm and fast conditions, combined with mounded fairways and elevated greens, present a "double-edged sword," according to McIlroy. While avoiding fairway bunkers remains key, some players might opt for more aggressive tee shots, accepting potential time in the rough. Ultimately, Royal Birkdale is expected to challenge golfers with strategic decision-making.
