The Nifty Ten Fifty 2019, will likely occur on April 6, 2019. The Nifty Mixty is like Mavericks Surf contest. We wait until conditions are right, then announce the event a week or so prior. The window is typically mid March through end of April. We look for lush green conditions, with tacky surface, but after the rains have subsided such that there is little to no mud.
