Swimming upwind is not very easy at all. In fact, It is a virtually an impossible task. On almost every breath, you inhale water. So you stop, spluttering, thinking that you are very stupid to do that. I happens all the time to me. It doesn't help that I usually swim in salt water, so you inhale seawater. The crawl stroke is best for swimming upwind. You breath to the side instead of the front. When you swim with a mask and snorkel, you overcome this problem.
