How this week got its score

  • 7 forecast days: 2 clear/mainly clear, 0 partly cloudy, 3 overcast, 2 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 8.0 × 0.55 = 4.42
  • Worst day drag: worst day is 6.5 × 0.25 = 1.62 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 6/7 = 86% coverage × 0.20 = 1.71
  • Best single day is 10.0 but it only counts through the trimmed mean - a lone great day cannot carry the window.
  • Advertised 3-day window (2026-08-06→2026-08-08) scores 9.4 on its own.
  • Legacy gate counted 4/7 days as "perfect sun"; this model counts 2 genuinely clear.
