What should I pack for a holiday in the Algarve during December?
During the day, it's usually warm enough to wear T-shirts and shorts, or dresses, but it pays to pack a pair of jeans just in case the temperature drops. As it can be rainy in the Algarve in December, you might want to pack a light raincoat too. For night time, bring a jacket to keep you warm. On your feet, you'll probably find that trainers or sandals are a comfortable option for day-time wear. At night, however, feel free to don your favourite pair of heels for a romantic dinner with your partner, or perhaps a trip to a local wine bar.

Anything else to be aware of when travelling to the Algarve during December?
Be aware that, as December is off-peak season for the Algarve, some tourist attractions (like the local waterpark, for example) may not be running during the time of your visit. If visiting during Christmas (as I did), you'll need to ensure you book Christmas Day dinner in advance and, while many venues remain open on Christmas Eve, many will, of course, be shut on Christmas Day.
