The biennial matchplay event between Europe and USA currently begins on a Friday but officials will look into bringing the start forward in 2010.
The move would spread the matches out, helping to combat Welsh autumn weather, and also increase revenues.
"It is a situation we are looking at," said Sandy Jones, chief executive of the Professional Golfers' Association.
"No decision has yet been taken and won't be for some time. Certainly not until later this year at the earliest."
The 2010 competition will take place at Wales' Celtic Manor but owing to a restructure of the American PGA season from 2007, the event is likely to move from its September slot to October.
But shortened daylight and the increased threat of inclement weather could hamper the event in its current format.
The 2006 Ryder Cup is set for the K Club outside Dublin, Ireland from September 22 to 24.
In 2008 the event will be staged at Valhalla, Kentucky, USA.
