This year's games season has been hit hard by the unseasonal summer weather.
The Tomintoul event has suffered in the past being called off in 2009, 2002 and 1987, but with tomorrow forecast to stay dry until early evening, chances are good.
Patricia Grant, committee secretary, said: "There have been a lot of games called off this year including Stonehaven and Loch Lomond, but the park looks not bad.
"Drainage was put in four years ago and it has worked.
"The weather has been abysmal but unfortunately we can’t control that."
She added: "We don’t do pre-booking so people enter on the day except for the dancing, we’ve got 90 so far."
The 171st Tomintoul games will begin at 11am with the highland dancing and the junior heavy events.
The official opening will take place at 1pm when the senior heavy events get underway with a full programme including tossing the caber, hammer and shot putt.
There will also be a hill race, piping and tug o’ war competitions as well as Ballater Pipe Band.
Tomintoul is one of the Grampian Games, a series of a dozen that takes place across the summer months and features the Glenfiddich Heavy Events Championship tournament.
The heavy athlete who gains the most points across 12 games will be crowned winner, with competition at Tomintoul expected to be fierce.
Jim Brown, chairman of the Grampian Games Association, said: "The heavies are one of the real highlights of any games and we are hoping to see some of the top names including reigning champion Bruce Robb and current championship leader Craig Sinclair competing at the weekend".
