The thing to do for any burn, immediately, is to grab a pack of frozen vegetables or an ice pack or ice in a baggie and apply it for 15 minutes to the burned area. This will reduce the pain, limit the spread of the burn, and be of great relief.
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.

Severe weather events are extremely rare during October. Even though the temperature in the Algarve is starting to cool down in October it is still a great time of year to visit. The temperatures can still hover around the mid 20âs at this time of year and on rare occasions can even exceed the mid 30âs.
