Become A South African Weather Guru

What is the difference between a weather forecast and report?

A weather forecast is given before the date in question and gives an indication of what weather conditions could be expected. Weather forecasts can be made one to two weeks in advance. The forecast skill however drops rapidly during the first week of a forecast, such that daily conditions generally become unpredictable after about a week to ten days.

A weather report can only be given for a past period and gives the actual weather conditions that hale already occurred. It can be produced for any time period for any place where the South African Weather Service has a first order station or an automatic weather station (AWS) in operation.
