Hello! It is very important to take into account how the weather will play out while doing water sports. The surf could be too high and could drown you or take you out so you can't get back in. There could be a hurricane just coming in and you would never know if you had not checked. The tide could go up in the area without you knowing about it and there will not be any land. There are several reasons as to why you should always check the weather when taking part in any water activities!
I hope this helped!
I am, yours most sincerely,
