It is vitally important to find out about the weather forecasts for the area where you plan to navigate.

Meteorology (from the Greek μετέωρον metéōron ‘high in the sky’, ‘meteor'; and λόγος lógos ‘knowledge’, ‘treatise’) is the interdisciplinary science of atmospheric physics, which studies the state of the weather, the medium atmospheric, the phenomena produced and the laws that govern it.
The weather forecast
Several times a day, at fixed times, the data from each meteorological station, from the ships and from the satellites arrive at the regional services in charge of centralizing, analyzing and exploiting them, both to advance the meteorology and to establish forecasts on the key weather it will do in the days to come. As the observations are repeated every 3 hours (according to the world synoptic schedule), the succession of the maps and diagrams allows us to appreciate the synoptic evolution: it is possible to see how the disturbances are formed or resolved, if the pressure and temperature are rising or falling , if the force of the wind increases or decreases or if it changes its direction, if the air masses that are directed towards such a region are humid or dry, cold or warm, etc. It thus seems quite easy to foresee the path that the disturbances will follow and to know the weather that it will do in a certain place after one or several days.
In reality, the atmosphere is a gigantic three-dimensional gas mass, turbulent and whose evolution is influenced by so many factors that one of them can unpredictably exert a preponderant action that disrupts the expected evolution in an entire region. Thus, the weather forecast is less insecure the shorter the anticipation and the smaller the space it refers to. For this reason, the forecast is classified as micrometeorological, mesometeorological or macro-meteorological, depending on whether the area is 15 km, 15 to 200 km or more than 200 km, respectively.
The forecasts are formulated in the form of bulletins, some of which are intended for citizens in general and others for certain branches of human activity and air and maritime navigation, agriculture, construction, tourism, sports, regulation of waterways, certain industries, natural disaster prevention, etc.
