The best time to visit Urubamba is during the dry season, which runs from April to October.During these months, you'll experience clear skies and less rain, making it ideal for exploring the Sacred Valley and its many archaeological sites. While it's generally sunny, evenings and early mornings can be quite cool, so do remember to pack layers. This period is superb for those planning extensive outdoor activities and sightseeing.The shoulder months of April, May, September, and October offer a good balance of pleasant weather and fewer crowds compared to the peak months of June, July, and August. This can be particularly appealing for couples or solo travellers looking for a slightly more relaxed experience without compromising on good weather.While November to March is the wet season, it can still be a good time to visit if you don't mind occasional rain showers. The landscapes are lush and green, and there are fewer tourists, which can mean better value on accommodation and tours.
