How this week got its score
- 6 forecast days: 0 clear/mainly clear, 0 partly cloudy, 5 overcast, 1 wet (fog/drizzle/rain/showers), 0 stormy.
- Trimmed mean of day scores 7.0 × 0.55 = 3.88
- Worst day drag: worst day is 5.4 × 0.25 = 1.35 - one bad day cannot be averaged away.
- Longest consecutive run of good days (≥7.0) is 3/6 = 50% coverage × 0.20 = 1.00
- Best single day is 7.2 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.
