How this week got its score
- 13 forecast days: 9 clear/mainly clear, 0 partly cloudy, 4 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
- Trimmed mean of day scores 9.5 × 0.55 = 5.24
- Worst day drag: worst day is 7.0 × 0.25 = 1.75 - one bad day cannot be averaged away.
- Longest consecutive run of good days (≥7.0) is 13/13 = 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.
