The best time to go to San Luis is typically during the dry season, from December to April.
During these months, you'll experience pleasant, sunny weather with lower humidity, making it ideal for exploring the town and surrounding natural beauty. The temperatures are comfortable for outdoor activities like hiking or visiting the nearby coffee plantations. This period also generally avoids the heavier rainfall that can occur in the wet season, ensuring your plans are less likely to be disrupted.
Couples looking for a relaxing escape will find these months particularly appealing. The clear skies and comfortable climate are superb for enjoying the scenic views and the generally unhurried pace of life in San Luis. It's a great time for leisurely walks and enjoying meals outdoors.
For travellers interested in local culture and traditions, visiting in December can be especially rewarding due to festive celebrations leading up to Christmas.
