Lisbon weather this week

Lisbon, PT Passport worthy

Lisbon scores 8.7 out of 10 and has no genuinely clear day in the next 16.

8.7/10
No clear day
0 genuinely clear days, 0 partly cloudy, 3 overcast, 0 wet, 0 stormy — out of 16 forecast days.
Bright days 0 vs dull days 3. 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 8.7 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 3 dull ones, expect grey skies. We are showing you the number and the contradiction rather than only the number.

3-day window, zero rain — Cool, grey, and dry — overcast all week, peaks around 75°F

How this week got its score

  • 3 forecast days: 0 clear/mainly clear, 0 partly cloudy, 3 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 8.3 × 0.55 = 4.58
  • Worst day drag: worst day is 8.3 × 0.25 = 2.08 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 3/3 = 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.
