The first day of the 2025 Open Championship is expected to be rainy, with periods of heavy rain that could accumulate up to a quarter of an inch. The high temperature is expected to be around 69 degrees, with a low of 57 degrees, and winds will range from 10 to 20 miles per hour, according to The Weather Channel.

Widespread showers in the morning become scattered in the afternoon on Friday, but forecasters expect a much lighter wind of 5-10 mph coming from the southwest with a high temperature around 65 degrees. Much of the same Saturday. Cloudy with off-and-on rain, high temperatures in the mid 60s and winds from the southeast at 5-10 mph.

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.
