Lisbon: The weekend and week ahead will be sunny and bright but those clear blue skies mean it will feel nippy during the day, with highs of 14 forecast, and very cold at night, when the mercury will plunge to around 4 degrees.
South: Even the normally-warmer southern Portugal won’t be able to avoid the chilly weather, although the coming week is looking clear and sunny. Daytime temperatures will still be mild, at around 18 degrees, but overnight lows will plunge to around 5.
North: Even northern Portugal will be bright and sunny for the foreseeable future although the temperatures will be a few degrees lower than in recent weeks, see-sawing between highs of 16 degrees Celsius and night-time lows of 3.
