Hey there. I've recently started learning about surfing. Have you ever surfed?
Only when I was very little. Is it hard?
It's sort of like riding a bike. You fall sometimes, but it gets better as you learn to balance.
Is it dangerous at all?
Riding a wave can be dangerous if it is a very high one, yes.
How cold does it get in the water?
The water temperature depends on which body of water you are surfing on. People have been known to utilize rivers, and even lakes for surfing.
