Tokyo weather this week

Tokyo, JP Passport worthy

Tokyo scores 8.1 out of 10 and has no genuinely clear day in the next 16.

8.1/10
No clear day
0 genuinely clear days, 0 partly cloudy, 3 overcast, 1 wet, 0 stormy — out of 16 forecast days.
Bright days 0 vs dull days 4. 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 8.1 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 4 dull ones, expect grey skies. We are showing you the number and the contradiction rather than only the number.

4-day window, 1.0% rain-affected — Warm, dry, and the sun never shows — zero clear days in 4, one rainy day

The next 16 days in Tokyo

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 16 days (100%), not the lowest, because the worst number is the useful one.

Booking window Sat 10 Oct–Tue 13 Oct: 8.1/10 for those days alone. The 16-day outlook score (8.1) covers the full table below and includes days outside that window.

Tokyo daily forecast, Tue 29 Sep to Wed 14 Oct (16 days total). Best single day scores 8.4; worst scores 4.1. A lone good day cannot carry the week.

How this week got its score

  • 4 forecast days: 0 clear/mainly clear, 0 partly cloudy, 3 overcast, 1 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 7.9 × 0.55 = 4.37
  • 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 4/4 = 100% coverage × 0.20 = 2.00
  • Best single day is 8.4 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.
