The Weston Irish Festival began in 2000 as a one-day event which drew an attendance of 1500 people. As the first act took the stage, on what had been a beautiful morning, the clouds rolled in and by the end of the day had dumped three inches of rain on the festival. In the true spirit of the Irish however, the audience stuck it out, the musicians did all they could by playing impromptu sets wherever there was a reasonably dry spot in between the rain showers, and everyone managed to still have a great time.

Since then the event has grown to a three-day festival and has featured many of the greatest acts in Irish Music including, The Dublin City Ramblers, The Makem Brothers, Young Dubliners, Seven Nations, The Elders, Connie Dover, The Prodigals, The Fenians, and Brigid's Cross. The attendance has experienced a controlled growth to about 7,000 people in 2007, which is a lively crowd but still retains the intimate feel of a small town festival.
