Hi!
As a beginner, you won't need 12kn of wind to learn this sport. Planing is not the only way to have fun on a windsurfer. Cruising in displacement mode can be fun too. It's just a different way to enjoy the sport and a different stage in your progression.
The sport doesn't seem to be dead. It's actually regaining some grounds and manufacturers have a hard time to fulfill the demand - maybe just a COVID effect, who knows?! But for sure, it is less popular than back in the 80s and 90s. But who cares, if it's fun to do, why worry about how popular or unpopular it is?
As far as maximizing your opportunities for sessions when the weather is right, work or any scheduled commitments are certainly getting in the way. However, once you can windsurf, you can learn how to windfoil (foil attached to the board instead of the fin) to get you going in more marginal - less windy - conditions. Proximity to a launch site can also be a factor that promotes frequency. And yes, the midwest is a great area to windsurf - whether on the great lakes or on inland lakes. This website has a full inventory of places to go to.
As far as learning, I have to admit, there are not a whole lot of options around. A couple I know; maybe a bit far but here they are:
- North Shore Windsurfing Club offers free initiation classes on Lake Winnebago during the summer months near Appleton, WI. Check their Facebook page for more info.
- Sheboygan Sailing School used to offer windsurfing clinics in the summer last year. Not sure this is still happening this year though. Located in Sheboygan, WI.
I'm not sure what's available in Illinois...
The best way to learn windsurfing is to take a vacation trip to a destination where you can dedicate a few hours over a few consecutive days with an instructor. Doing it on your own would be frustrating especially if you've never had an experience sailing on anything. Here are a couple of great places to learn:
- The Outer Banks in NC (Avon, NC) is a great place to do that: Warm and shallow waters, steady moderate wind in summer, experienced windsurfing instructors
- For a more exotic destination, the lovely island of Bonaire, Dutch Caribbean: 86 degree year-round, great for a winter vacation, tropical shallow lagoon, top-spot to learn and progress, great vacation spot with world-class diving activity.
Anyone I know that has been patient enough to engage with this sport has been hooked for life! Not the easiest sport around but very rewarding for those who put the effort.
Good luck!
