I'm a 18 stone fat guy and I wanna learn to surf

Hello!
I'm a fat 18 stone guy who wants to learn to surf.
I've messed about on a foamie a few times and that's made me decide I want to learn how to surf
I'm in the process of loosing weight, I was 20 stone and I'm now 18 stone so I'm on the right path with weight loss but I'm a long way from where I should be.
I know you have to be fit to surf well but my question is can I learn to surf now or do I need to loose more weight before I can start to learn?
Thanks in advance!
