👉 A bellweather is a type of weather forecast that provides information about the likely conditions for a specific period of time. It is used to predict the weather and help people plan their activities or make decisions in advance, such as choosing the right time to go on a hike, visiting a beach, or attending a concert. Bellwarks are often given by meteorologists or weather forecasters who use data from satellites, balloons, and other instruments to predict the movement of clouds, precipitation, and temperature changes
