Lisbon: Despite crystal clear skies and being bright and sunny the capital will feel very cold for the foreseeable future as clear skies mean icy temperatures; maximums will be of around 14 degrees Celsius and minimums of 3.
South: Southern Portugal will also be bright and a couple of degrees warmer than the rest of Portugal, especially from Monday, when some cloud-cover moves in. Readings will range between highs of 17 degrees and lows of 5.
North: Even the north will be sunny, but still very cold, with temperatures closer to those of southern Portugal. The mercury will rise very gradually towards the end of the coming week, when cloud and light showers are forecast.
