The best time to go to Lomas, Arequipa Region, Peru, is during the dry season, which runs from April to November.
This period offers consistently clear skies and comfortable temperatures, making it ideal for outdoor activities like exploring the beaches and nearby archaeological sites. The weather is generally sunny with average daytime temperatures ranging from the low 70s to low 80s Fahrenheit, and cooler evenings.
For travelers interested in marine life and coastal exploration, the months of September through November are particularly good. This is when the Humboldt Current is more active, bringing a greater abundance of marine species closer to the shore, which is excellent for snorkeling, diving, or boat excursions.
If you prefer a quieter experience with fewer crowds, late April and May, or October and November, are excellent choices.
