All Months
April through October gives you the best weather — dry skies, warm days around 70°F, and cool nights that rarely drop below 40°F. This is peak season though, so expect crowds at major sites and higher prices for tours. The rainy season from November to March brings afternoon downpours that can flood streets and make Colca Canyon trips tricky. But here's what locals know — the rain usually hits after 2pm, leaving mornings clear for sightseeing. Plus accommodation prices drop by 30-40%. May and September hit the sweet spot with great weather and smaller crowds. The city celebrates its founding every August 15th with parades, fireworks, and street parties that take over the historic center. Just book accommodation well in advance if you're coming for the festival.
