Lisbon: The Portuguese capital will be mild and humid this weekend, but should see the sun dominate from the middle of next week after the odd shower in between days.
The South: Temperatures in southern Portugal will start the weekend sitting around season averages before climbing to between 15 at night and 25 in the day by the end of the coming week.
The North: Northern parts of the country should be slightly warmer than central Portugal, and in many ways will resemble the weather down south except at night, when lows could still fall to single digits.
