Algarve weather this week

Algarve, PT Passport worthy

Algarve scores 9.0 out of 10 and has exactly one genuinely clear day in the next 16. Dull days (6) still outnumber bright ones (5), so this is not a good week.

9.0/10
Mostly dull
1 genuinely clear day, 4 partly cloudy, 6 overcast, 0 wet, 0 stormy — out of 16 forecast days.
Bright days 5 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 9.0 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.

11-day window, zero rain — The clouds are winning — 1 clear day out of 11 plus 4 partly cloudy, 82°F

The next 16 days in Algarve

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 (11%), not the lowest, because the worst number is the useful one.

Booking window Thu 8 Oct–Sun 18 Oct: 9.0/10 for those days alone. The 16-day outlook score (9.0) covers the full table below and includes days outside that window.

Algarve daily forecast, Thu 8 Oct to Fri 23 Oct (16 days total). Best single day scores 10.0; worst scores 4.0. A lone good day cannot carry the week.

How this week got its score

  • 11 forecast days: 1 clear/mainly clear, 4 partly cloudy, 6 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 8.9 × 0.55 = 4.87
  • Worst day drag: worst day is 8.4 × 0.25 = 2.10 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 11/11 = 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.

The full model, including why a single great day cannot rescue a bad week, is on the methodology page.
