Big Sur weather this week

Big Sur, California

Big Sur scores 7.9 out of 10 and has exactly one genuinely clear day in the next 7. Dull days (6) still outnumber bright ones (1), so this is not a good week.

7.9/10
Mostly dull
<built-in method clear of dict object at 0x7ce2615a4f00> genuinely clear days, 0 partly cloudy, 6 overcast, 0 wet, 0 stormy — out of 7 forecast days.
Bright days 1 vs dull days 6. Dull wins, so we do not call this a good week.
We are not showing a flattering tier word here. Why the score and the sky can disagree.

The model gives this week 7.9 out of 10 because it is warm and largely rain-free, and those are the two things the score measures. It is not measuring sunshine. With 1 genuinely clear day and 6 dull ones, expect grey skies. We are showing you the number and the contradiction rather than only the number.

How this week got its score

  • 7 forecast days: 1 clear/mainly clear, 0 partly cloudy, 6 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 7.6 × 0.55 = 4.18
  • 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 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 (2026-08-10→2026-08-12) scores 8.2 on its own.
  • Legacy gate counted 6/7 days as "perfect sun"; this model counts 1 genuinely clear.
