Everybody expects the 2025 U.S. Open to be a grind. 

Oakmont Country Club, this year’s host, is widely considered to be one of the toughest golf courses on the circuit, and the USGA prides itself on setting up the tournament to be an arduous test for the players.

As if that wasn’t enough, it does look like Mother Nature may also get involved, which should further complicate things for players – and bettors.

The U.S. Open should get off to a banner start with no rain projected for Round 1.

There is also very little wind in the forecast, which should give the players an honest look at Oakmont out of the gates.

The most notable bit of the forecast is that we could see temperatures in the mid-to-upper 80s.

Things aren’t quite ominous Friday, but there is a chance we see some disruption in play, most likely in the late afternoon.

There is just a 20 percent chance of precipitation at any point Friday, but it’s not out of the question for a thunderstorm to show up toward the end of the day.

Temperatures will be lower than Thursday, likely settling in the upper 70s. The wind should be a non-factor.

This is when Mother Nature begins to rub her hands together.

The forecast calls for a 50 percent chance of showers and storms in the afternoon, with heavy rain and lightning both possible. 

The tournament brass will want to avoid an early start Saturday, but if this forecast gets uglier, we could see tee times get moved up for Round 3 in order to avoid the afternoon storms, especially since Sunday’s weather also looks iffy.

The final round could be chaotic, as the current forecast looks similar to Saturday’s.

The forecasters are saying there’s a 50 percent chance of showers and storms, but that number could move in either direction as we get closer.
