How this week got its score

  • 7 forecast days: 0 clear/mainly clear, 2 partly cloudy, 5 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 6.5 × 0.55 = 3.55
  • Worst day drag: worst day is 5.5 × 0.25 = 1.38 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 1/7 = 14% coverage × 0.20 = 0.29
  • Best single day is 7.1 but it only counts through the trimmed mean - a lone great day cannot carry the window.
  • Advertised 3-day window (2026-08-09→2026-08-11) scores 6.2 on its own.
  • Legacy gate counted 7/7 days as "perfect sun"; this model counts 0 genuinely clear.
