Traveller notes on Piran in October
Notes from nearby Venice (97 km away)
Piran doesn't have its own notes for October yet — these are about Venice, close enough to share the season.
Venice's forum calls October generally kind — average highs around 19°C, often light-jacket weather with a chance of morning mist off the lagoon, cooling further and greyer by month's end. Regulars flag evenings as too cool for outdoor dining by mid-month, and note the city is never quiet but is noticeably calmer than mid-summer.
