Small groveling knee to thigh high wave surfable 12 months out of the year with a longboard, very high volume board, bodyboard, or surfmat just about every day of the year.
Located mile south of Platte River Trail Parking Lot (E 88th Ave & Colorado Blvd, Thornton, CO) walk south looking for the boat chute wave and CRSA "Dave's Wave" sign on the right side of path. Dave's Wave is surfable twice daily due to guaranteed releases of water and the wave comes in at about 200cfs when the stream gauge marker on the rock above the wave hits the .5 foot dot mark. Go with someone who has surfed the spot before or watch vids of Dave's Wave and use durable fins because they will be hitting the bottom at times. Wave blows out at 400cfs and will be best to find surf elsewhere.
