Summers are the best mostly because you may enjoy being in the water all day, no matter whether you are at the seaside or pool. In those cases, good swimmers are more than necessary, because no matter how people enjoy, there is always a risk that someone will drown or be in danger. In that case, if you are a good swimmer, perhaps with the first aid certificate, you are eligible to apply for this job in France, and spend your summer enjoying and holding everything under control. Yes, there is always a risk that something bad may occur, but in 99% nothing actually happens, so even though you should always be ready, do not push yourself so far to the point of not enjoying the fact you are working in France.
