It depends the exact time you go, as usually September is hot in the beginning of the month and tends to gets a little bit colder at the end of the month. I would say that in the south (Algarve) the weather should be around 25Â°C, and still probably beach weather. In Lisbon it would probably be colder, probably around 20Â°C, so probably not the right weather to go to the beach.
