October is an excellent "shoulder season" month to visit Lake Garda if you prefer crisp, cool weather and fewer crowds. In October 2026, temperatures typically range from a daytime high of 17∘C (63∘F) to a nighttime low of 8∘C (46∘F). The lake is surrounded by stunning autumn foliage, making it a prime time for photography and lakeside hiking. While the water is generally too cold for swimming, the "crisp air" is perfect for exploring the lakeside towns of Riva del Garda or Sirmione without the oppressive heat of July. You should expect about 5 hours of sunshine per day and roughly 8 days of rain throughout the month, so carrying a light waterproof jacket is a peer-to-peer "must." The best part of an October visit is the significant drop in prices for luxury hotels and the authentic atmosphere of the local harvest festivals, where you can sample fresh olive oils and regional wines without fighting through massive tourist throngs.
