Seattle weather this week

Seattle, Washington

Seattle scores 8.8 out of 10 and has no genuinely clear day in the next 7.

8.8/10
No clear day
0 genuinely clear days, 0 partly cloudy, 7 overcast, 0 wet, 0 stormy — out of 7 forecast days.
Bright days 0 vs dull days 7. 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 8.8 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 0 genuinely clear days and 7 dull ones, expect grey skies. We are showing you the number and the contradiction rather than only the number.

7 cloudy / 0 wet days, no clear days in 7 — Cool, grey, and dry — overcast all week, peaks around 84°F

The next 7 days in Seattle

Every number below is the forecast we hold, rendered as text — nothing here is drawn on a canvas or filled in by JavaScript. The rain figure is the highest chance across all 7 days (2%), not the lowest, because the worst number is the useful one.

Booking window Thu 13 Aug–Sat 15 Aug: 8.8/10 for those days alone. The 7-day outlook score (8.8) covers the full table below and includes days outside that window.

Seattle daily forecast, Thu 13 Aug to Wed 19 Aug (7 days total). Best single day scores 8.5; worst scores 8.5. A lone good day cannot carry the week.

How this week got its score

  • 7 forecast days: 0 clear/mainly clear, 0 partly cloudy, 7 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 8.5 × 0.55 = 4.68
  • Worst day drag: worst day is 8.5 × 0.25 = 2.12 - 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 8.5 but it only counts through the trimmed mean - a lone great day cannot carry the window.
  • Advertised 3-day window (2026-08-13→2026-08-15) scores 8.8 on its own.
  • Legacy gate counted 7/7 days as "perfect sun"; this model counts 0 genuinely clear.
