Rain, wind and rising weekend heat could all impact the 2026 PGA Championship as Aronimink prepares to test a loaded 156-player field.
The 2026 PGA Championship weather forecast could become one of the defining storylines this week as the 108th edition of the major arrives at Aronimink Golf Club in Newtown Square, Pennsylvania.
The year’s second major begins Thursday, May 14, with a 156-player field chasing the Wanamaker Trophy, but course conditions may shift quickly.

Early-week sunshine should give players a clean window for final prep, with Tuesday and Wednesday expected to bring cool mornings, afternoon temperatures in the 60s and manageable winds.
The real concern arrives late Wednesday, when showers and possible storms are expected to move into the Philadelphia area.
Any overnight rain could soften Aronimink before the opening round, especially if lingering showers delay or complicate early Thursday tee times.
Thursday’s forecast calls for temperatures from the mid 50s into the mid 60s, with wind gusts that could climb above 20 mph.
That combination may reward patient ball-strikers and players who can handle changing green speeds. Friday looks drier, but stronger gusts could still make club selection tricky as the field battles to reach the weekend.
The cut at the PGA Championship will come after 36 holes, with the top 70 players and ties advancing. That differs from most PGA TOUR full-field events, which usually cut to the top 65 and ties.
By the weekend, Aronimink could play differently again. Saturday is expected to be warmer and sunnier, with highs pushing near 79 degrees.
Sunday may bring the best scoring conditions of the week, with temperatures rising into the mid 80s and only a small chance of rain.

If the championship is tied after 72 holes, the PGA of America will use a three-hole aggregate playoff on Nos. 10, 17 and 18. If needed, sudden death would follow on No. 18.
That means the winner may need more than elite form. He’ll need the right weather window, too.
