Why can't the previous weather forecast be found?

Weather forecast is a kind of forecast, which solves the future weather problem, so it is called forecast. The past weather should be the recorded data of the actual weather, but not the forecast. If it is used, you can check it with the Meteorological Bureau. Of course, you have to pay.

Just because it is no longer a prediction, it loses the meaning of consultation, so it will not be discovered again.
