How this week got its score

  • 9 forecast days: 9 clear/mainly clear, 0 partly cloudy, 0 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 10.0 × 0.55 = 5.50
  • Worst day drag: worst day is 9.8 × 0.25 = 2.45 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 9/9 = 100% coverage × 0.20 = 2.00
  • Best single day is 10.0 but it only counts through the trimmed mean - a lone great day cannot carry the window.

The full model, including why a single great day cannot rescue a bad week, is on the methodology page.
