While you’re out on the water enjoying yourself, you don’t want to be worrying about if you’re getting too much sun or if you’re going to end up with a wicked sunburn on your face. And you definitely don’t want to end up cutting your paddling time short just because you’re not protecting yourself from the sun’s rays.
Always wear a good sunblock before hitting the water with your SUP. Even if it is not a particularly sunny day, you should still apply sunscreen because the sun’s UV rays can still reach your skin. And long term sun exposure can lead to skin cancers and all sorts of other unpleasant experiences – including early wrinkling of your skin!
