St. Augustine weather this week

Just your ID

St. Augustine scores 8.3 out of 10 and has exactly one genuinely clear day in the next 16. Dull days (6) still outnumber bright ones (1), so this is not a good week.

8.3/10

Mostly dull

1 genuinely clear day, 0 partly cloudy, 5 overcast, 1 wet, 0 stormy — out of 16 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 8.3 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, 5 overcast, 1 wet (fog/drizzle/rain/showers), 0 stormy.
Trimmed mean of day scores 8.3 × 0.55 = 4.55
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 9.8 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.
