Sailing is one of the sports that is dependent on the meteorological conditions, present at any given moment. The interaction of wind, sea and sailing forces is what transforms this recreational sport into the complex sport. There is a big difference between recreational sailing and racing sailing. Many people who are engaged in recreational sailing often do not worry much about weather, and apart from listening to weather news, they show little interest in getting to know the basic facts about the development of weather conditions at sea. Regatta sailing is something else, regatta sailing is characterized by tactics, and tactics are prepared before the race itself. On the start date, weather may change, and the original forecast may not be accurate, so one should know how to read all the signs on the sky that tell us how weather will change during the race. This can only do experienced sailors, whose travel planning and knowledge of the development of time is not a secondary one, but a primary activity on the sea. In this final work, we will thoroughly go through the basics of meteorology, and try to explain more closely all conditions arising from meteorology and affecting sailing and in what way affecting it.
