The temperature in the south of Portugal during the day are around 12-20°C (usually sunny). During the night, temperatures usually drop to 12-15°C, but may decreases to 8°C at the most. Anyway, you will get always from us a very cosy and warm blanket that is suitable for these temperatures. In case you want to have it even warmer, book with us your heater. Electric heater (1000 W) with a 230V extension cord (25 m) that can be used on campsites to heat-up the van during winter (e.g., during the night). You must connect it to the electric grid in a campsite.
