Orvieto sits on a flat tuff cliff 325 metres above the Umbrian valley floor, giving it a climate distinct from the surrounding lowlands. The elevation means cooler nights year-round and more wind exposure than valley towns like Todi or Perugia. The city has a warm-summer Mediterranean climate (Koppen Csb) with cold, damp winters and hot, dry summers. Annual rainfall averages 793 mm, with November the wettest month (110 mm) and July the driest (32 mm). The mean annual temperature is 13.9°C (57°F).

Winters in Orvieto are cold and damp. January is the coldest month, with daytime highs around 10°C (50°F) and overnight lows dropping to 2°C (35°F).

Orvieto Weather by Month: Spring (March to May)

April averages 68 mm of rain across 9 days. The key challenge is layering: mornings in March can be 4°C (39°F) while afternoons feel like early summer.

Orvieto Weather by Month: Summer (June to August)
Summers are hot, dry, and the busiest season. July and August both see average highs of 30 to 31°C (86 to 88°F), with July the driest month at just 32 mm of rain over 4 days. The tuff stone buildings provide natural insulation, but midday sightseeing on the exposed Piazza del Duomo can be brutal. Humidity is moderate (55 to 60%). Evenings cool to 17 to 18°C (63 to 64°F). Sunshine peaks at 10 hours per day in July. August 15 (Ferragosto) sees many Italian businesses close for a week, though tourist-oriented restaurants mostly stay open. Pack light cotton, sunglasses, sunscreen, and a refillable water bottle. See also our best neighborhoods in Orvieto for more information.
