How this week got its score

  • 7 forecast days: 2 clear/mainly clear, 1 partly cloudy, 4 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 8.6 × 0.55 = 4.72
  • Worst day drag: worst day is 7.9 × 0.25 = 1.98 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 7/7 = 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.
  • Advertised 3-day window (2026-08-06→2026-08-08) scores 9.1 on its own.
  • Legacy gate counted 7/7 days as "perfect sun"; this model counts 2 genuinely clear.
