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.

The final men's major of the year is here, as the 2025 British Open Championship kicks off Thursday morning at Royal Portrush 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.
