Arequipa Weather in October

October weather

October is warm, sunny and very dry in Arequipa. Afternoons reach 27°C, while nights cool to 11°C. Rain is rare, so you can spend long days exploring the historic centre, Santa Catalina Monastery and the viewpoints in Yanahuara. The clear, dry weather also suits a day trip towards Colca Canyon.

The midday sun can feel strong at Arequipa's altitude, so save your longer walks around the Plaza de Armas for morning or late afternoon. October isn't the hottest month: its daytime high matches November's, and September is only slightly cooler.

Events and local life

Peru marks the Battle of Angamos on October 8. It's a national holiday, though the scale of celebrations varies by place. You may also see processions for the Lord of Miracles, a major October tradition across Peru. In Arequipa, ask locally about routes and timings before setting out; processions can affect traffic around the centre.

For couples who enjoy wandering, the evenings around San Lázaro's narrow lanes feel especially pleasant once the day's heat eases.

Crowds and practical tips

October is generally calmer than Arequipa's busy dry-season months, especially July and August. You'll often find the main sights easier to enjoy, and accommodation prices may feel less pressured than during peak season. It's not empty, though, and the October holiday can bring extra local travel.

At the Santa Catalina Monastery, take a break in its shaded courtyards between sunny streets. For lunch nearby, try rocoto relleno, Arequipa's spicy stuffed pepper; ask how hot it is before ordering.
