how much rain does lisbon get
Summer temperatures are warm and sometimes hot, while winters are mild and damp. Lisbon sees a lot of sunshine (over 3300 hrs per year) and about 100 days of rain a year. The Atlantic Ocean strongly influences the weather in Lisbon, primarily as a consequence of the nearby flow of the Gulf stream. These currents ensure that the coastal city of Lisbon does not experience the extreme temperatures that can occur in central Portugal and Spain. While on average about 600 mm, or 24 inches, of rain falls annually in Lisbon, the precipitation is spread out over 100 days of the year, so there are rare days without at least some sunshine. Like anywhere in the world, weather varies year on year in Lisbon and averages don't tell the whole picture.
