How to use the Sfax planner
Start with the live current-category teaser, choose the activity, then use the email reveal for a complete hourly comparison. AirAgora evaluates complete two-hour windows starting between 06:00 and 22:00 local time. It gives 70% of the score to mean severity and 30% to the worst hour, keeps an earlier window when scores are materially tied, and avoids naming a winner when the difference is too small.%!(EXTRA string=Sfax)
If every practical period remains in a poor category, the result is described as the least polluted available window rather than as good or safe. Missing hours, provider errors, and stale data remain visible instead of being filled with invented values.
