Lisbon: Besides a few lingering clouds on Friday the rest of the weekend is looking clear and bright in the capital. But that does mean chillier temperatures. Highs will sit at around 14 degrees Celsius over coming days while lows will drop to 6.
The South: The forecast for the Algarve is very similar to that of Lisbon, with thermometers only rising a degree or two higher and overnight lows being slightly cooler. The weekend will overall be clear and sunny, at highs of 16 degrees Celsius and lows of 5.
The North: Temperatures in northern Portugal will be among the coldest in coming days, with daytime highs reaching the low teens, and minimum dropping to close to zero. The north will otherwise also see clear skies with just a few clouds around on Sunday.
