Weather forecast in Barcelona

Below is a comparison of websites related to weather forecast for Barcelona. We've classified as if they hit or not, in their predictions.

Meteorology is not an exact science, but in Spain there are rivalries between cities and this causes the weather forecasts are different from each other. The predictions from Madrid, tend to predict too much rain over Barcelona. The predictions from the tourist office in Barcelona, tend to predict too much sun. Although, in general, when the weather is changing, everyone is a disaster, and all fail a lot.

At positions 8, 9 and 10 are the websites that tend to always put sun when rain is likely (Meteo Cat) or vice versa, websites that have a malicious forecast with two weeks straight of rain over Barcelona, in summer (July 2011) when in fact virtually not a drop fell (AEMET and Quetiempo), and now something similar is happening with TuTiempo (year 2023).
