Until a few years ago, long-term weather forecasts were fairly accurate. But recently, against the background of global warming and changes in almost all weather parameters, it has become much more difficult to make long-term forecasts. The most accurate weather forecast in Santiago is given for a period of 1 to 7 days. The most accurate data is the weather for today, the weather for tomorrow, or the weather forecast for the week. The weather forecast for a month is considered long-term. This is not to say that it is unreliable. It's just not as accurate as the short-term one. It should be noted that it is compiled through a series of meteorological measurements. Weather data for the previous days of the month are also taken into account. In the northern regions, the weather is more stable for forecasting. The southern regions are characterized by the active occurrence of atmospheric fronts, which brings precipitation, strong winds, thunderstorms, and hurricanes. The influence of the sun and the difference in temperature of the air masses play an important role in forecasting. Pronounced seasonality allows making a more accurate forecast. It determines the clear time intervals of the year.
