How this forecast got its score

  • 5 forecast days: 0 clear/mainly clear, 1 partly cloudy, 4 overcast or foggy, 0 with a drizzle/rain/snow sky code, 0 stormy (sky codes; rain hours below).
  • Trimmed mean of day scores 8.5 × 0.55 = 4.68
  • 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 4/5 = 80% coverage × 0.20 = 1.60
  • Best single day is 9.2 but it only counts through the trimmed mean - a lone great day cannot carry the window.
  • Hourly forecast: rain on 1 of 5 days (2h): 12 Nov (2h).
  • Whole 16-day forecast: 5 clear, 2 partly cloudy, 6 overcast or foggy, 3 with a rain sky code, 0 with a storm sky code; rain hours on 4 of them (63h).
