Mark Sponsler grew up on an avocado farm outside Miami. One day an avocado ricocheted off his window shutters during a storm, and something clicked. He’s been obsessed with weather ever since. He graduated from Rollins College in 1980 with a degree in Business Administration, then spent years managing software projects for companies like Rockwell International and Lockheed-Martin. Not exactly the resume you’d expect from the guy who predicts Mavericks swells down to the hour. In 1998, Mark launched Stormsurf. It started as an email thread between local surfers. Now it’s the source big-wave surfers actually trust. Stormsurf has consulted on IMAX films, Nightline, 48 Hours, and was the lead forecasting source for the movie Chasing Mavericks.
