Autumn leaves might be falling from the trees, but temperatures still resemble those seen during summer. But the North, after a warm weekend, will see temperatures drop at the beginning of next week.

Lisbon: The capital will be enjoying a very hot weekend, with thermometers set to reach highs well into the 30’s. Maximums will drop slightly during the course of the coming week.
The South: Blue skies and warm weather will once again be the order of the day in southern Portugal in the next seven days, with no sign of rain in sight.
The North: Northern Portugal will see highs drop to around 22 degrees Celsius next week, with a slight chance of rain by next weekend.
