A daily rainfall total says little on its own: the same 5 mm can be one short downpour or a grey day of drizzle, which is why the hourly chart above is often the more useful of the two. Over the next fortnight the highest UV index for Bilbao is 7 — high enough to warrant sun protection in the middle of the day.

How reliable is a 14 day forecast?

The first three to five days are generally very accurate. After that the certainty drops off and it is better read as a trend than as an exact daily prediction.
