What are the ideal conditions for learning how to wingfoil? Anything really, just get out there and give it a go!
But on a more serious note, if you do have a choice, we would suggest 12-15knots windspeed and as flat water as possible. The wind speed may seem a bit high and some might even be thinking: "Well I could be kitesurfing in that wind", and yes you would be right. But as a beginner it is simply easier to have a little extra power with an average size wing rather than to struggle keeping the wing up in super light winds! Depth is also super important of course, as you need to have enough space for your foil. These are the perfect conditions in our opinion. Of course, that doesn’t mean you can’t learn in anything else. Wingfoiling is still foiling, so you could go out and try with just 10 knots. It will be harder to fly for sure, but not impossible, especially with the right gear! The same goes for stronger winds. A smaller wing will allow you to have control and if anything, stronger winds will get you flying sooner. Also, don’t worry too much about some chop or small waves. Once you have good wing control, you will be surprised at how much balance that gives you on a board! Not to mention that if you learn in waves then everything else later on will seem normal or easy. Transitioning from flat to waves is where the real challenge is.
