Wes, who celebrates his 22nd birthday today, has recently been out with an ankle injury but recovered to play well in a recent development squad game.
He's now joined the Glovers, who are riding high near the top of League One after an outstanding run recently and they have reported that he will go straight into the squad for this weekend's game against Tranmere.
Wes is yet to play league football for Burnley, his only two appearances in the first team have both come in the League Cup, against Morecambe in 2010 and in the home win against Burton in 2011, both as a substitute.
He has previously been out on loan in League Two with Grimsby, Accrington and Crewe, and this will be his first opportunity to play League One football.
He becomes the seventh player to go out on loan, joining Tom Anderson, Steven Hewitt, Cameron Howieson, Shay McCartan, Alex MacDonald and George Porter.
