In just 72 holes, a player can turn a somewhat-mundane season into a memorable one, a memorable season into a historic one and a historic season into one of an all-time great campaign. That's what is on the line this week at the 2025 Open Championship as Royal Portrush hosts the final major of the season in Northern Ireland.

Here’s the projected weather forecast for the 2025 Open Championship, which begins on Thursday morning at Royal Portrush in County Antrim, Northern Ireland. The tournament gets going at 6:35 a.m. local time (1:35 a.m. ET), and it’s dicey whether we will get the full round of play in due to thunderstorms.

Here are the groups that will be playing together in Round 1 of the 2025 Open Championship, plus their tee times. Coverage of the 2025 Open Championship can be found on NBC, USA Network, Peacock, and Golf Channel. Anyone looking to stream the event can do so with Fubo.
