How this forecast got its score

  • 3 forecast days: 0 clear/mainly clear, 0 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 8.5 × 0.55 = 4.68
  • Worst day drag: worst day is 8.5 × 0.25 = 2.12 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 3/3 = 100% coverage × 0.20 = 2.00
  • Best single day is 8.5 but it only counts through the trimmed mean - a lone great day cannot carry the window.
  • Hourly forecast: no rain hours in any of the 3 days.
  • Whole 16-day forecast: 5 clear, 0 partly cloudy, 6 overcast or foggy, 5 with a rain sky code, 0 with a storm sky code; rain hours on 6 of them (70h).
