When to change to winter tyres in Bergamo
Development preview: the climate figures on this page come from a synthetic sample dataset, not real measurements. The page is hidden from search engines until real data is in place.
Bergamo stays mild for longer: the 5-day average usually only drops below 7 °C around 7 December, so most drivers can wait until November.
Typical best window
21 November – 28 November
For an experienced driver on city roads, from climate averages. Novice drivers: 12 November – 19 November.

Frost is rare in November (about 0 days on average), so the 7 °C rule — not frost — usually decides the date.
The date varies a lot from year to year: over the last 10 autumns the 7 °C rule triggered as early as 8 November and as late as 8 January. Check the live forecast each year rather than relying on a fixed date.
Backtest: in 10 of the last 10 autumns, changing within this typical window would have put winter tyres on before the first slippery day (frost on a wet road or snow).
