The best time to visit Mar Del Sur is during the summer months, from December to March, when the weather is warm and sunny, great for enjoying the beaches and outdoor activities.
During this period, you can expect average temperatures ranging from 20°C to 28°C, with plenty of sunshine. This is ideal for swimming, sunbathing, and exploring the coastal area. December and January are particularly popular, as they coincide with the main holiday season in Argentina, so the town will be lively with more restaurants and shops open.
For those looking for a slightly quieter experience while still enjoying good weather, late February and March are excellent alternatives. The crowds begin to thin out, but the pleasant temperatures and sunny days persist, offering a more relaxed trip. You'll still find most facilities operating, making it a great time for couples seeking a peaceful getaway.
If you are a solo traveller who prefers cooler weather and fewer people, the shoulder seasons of November or April can also be appealing.
