How this forecast got its score

  • 5 forecast days: 1 clear/mainly clear, 1 partly cloudy, 3 overcast or foggy, 0 with a drizzle/rain/snow sky code, 0 stormy (sky codes; rain hours below).
  • Trimmed mean of day scores 7.4 × 0.55 = 4.09
  • Worst day drag: worst day is 6.2 × 0.25 = 1.55 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 3/5 = 60% coverage × 0.20 = 1.20
  • Best single day is 10.0 but it only counts through the trimmed mean - a lone great day cannot carry the window.
  • Hourly forecast: rain on 2 of 5 days (4h): 11 Nov (3h), 12 Nov (1h).
  • Whole 16-day forecast: 6 clear, 1 partly cloudy, 8 overcast or foggy, 1 with a rain sky code, 0 with a storm sky code; rain hours on 3 of them (20h).
