The weekly forecast includes a general and not detailed forecast, which can give an idea of the overall and average expected conditions, and how much this situation can differ from the typical climatological conditions of the period.
We highlight that the reliability of the weekly forecast is generally medium-low. The first week is usually the most reliable, whereas often the third week is more similar to the climatology of the period.
The goal of this section is to give an idea of the average weekly behaviour which differ from the evolution of individial meteorological events.
