September is widely considered one of the absolute best months to visit Lake Garda, often described as a "second summer." During this time, the oppressive heat and intense humidity of July and August have faded, replaced by comfortable average highs of 24°C (75°F) and cooler, crisp evenings around 14°C. The water temperature remains warm enough for swimming (averaging 20°C), making it ideal for those who want a beach experience without the suffocating crowds of the peak season. September is especially popular with food and wine enthusiasts, as it marks the start of the harvest season and features major events like the Bardolino Grape and Wine Festival. While it is technically one of the wetter months, the rain typically comes in short, heavy bursts rather than prolonged gloom. For 2026 travelers, September offers a perfect balance: all ferries and attractions are still operating on full summer schedules, but the overall atmosphere is significantly calmer and more relaxed.
