Saturday and Sunday in Zanzibar compared on the same forecast: Weather Score, high and low, rain chance and amount, maximum wind, sky and UV, with the better day named and the margin shown. Weekends more than four days out carry a note that the ranking can change with newer model runs.
Any weather decision in Zanzibar starts from the light budget. In September the location gets about 12 h 7 min of daylight, with the sun peaking 84° above the horizon — that sets how warm afternoons run, how long outdoor plans stay viable and how much usable photographic light the day contains. The scores above layer the live Open-Meteo forecast on top of that baseline.

Scores are capped by dealbreakers — heavy rain, dangerous wind, thick fog or hazardous UV pull a day down no matter how pleasant the rest of the numbers look.
