The best time to visit San Luis is during the dry season, which runs from May to October.
During these months, you'll experience consistently pleasant weather, with less rainfall and clearer skies, making it ideal for exploring the natural beauty and outdoor activities the region offers. The days are generally sunny and warm, while evenings are cool and comfortable.
This period is particularly good for those looking to hike and enjoy the stunning Andean landscapes without the interruption of heavy rains. The trails are more accessible, and the views are often unobstructed. It's a great time for couples or solo travellers who want to make the most of the outdoor adventures.
While November to April is the wet season, it can still be a good time to visit for those who don't mind occasional rain showers and want to see the countryside at its most lush and green.
