Historical disruption baseline
Typical disruptions in October
Based on 30 years of historical data, these are the disruption patterns most likely to affect plans in October.
Cold feels-like nights Measures: Cold feels-like nights (min <=5C). Observed about 28% of days (8.7 days/month) in October. Historical risk signal only, not a day-by-day forecast.
Likely frequency
8.7 days / month
- Share of days
- ~28% of days
- Upper edge
- Up to ~5°C (P95)
Why this matters
Cold feels-like nights are possible on ~9 days. Long outdoor blocks become harder to sustain, so layer up and keep a warm indoor fallback nearby.
