The 36th street wave probably won't be in. The Weir just 5 minutes east of downtown Boise past the golf course is lots of fun, great front and back surfing, 360, sidesurfs etc, always good but shallow, generally folks are there most afternoons and evenings. A step up is the Gutter, Bladder wave and Fishladder at Horseshoe Bend approximately 30 minutes from Boise. The Gutter can be real playful and retentive, with a good recovery pool. Tuck tight it can be shallow. I have not been there when the Bladder wave is in, but I hear it is great. When I am in Boise I never miss a chance to hit both play spots.
