In the case of islands, isn't it the temperature differential? (By
mid-afternoon, the land is warmer than the surrounding ocean, or something
like that.......) OTOH of my year in Indonesia (Malang, eastern upland
[+/-700m] Java), the daily rains (never torrential) came in mid/late
afternoon starting around January.  The worst I remember was a 3 week period
in Makassar (sea level) when it rained for the entire period, often
torrentially, with only occasional let-ups. Horrible, cold, clammy.

Do you, or anyone, know of a book or online resource that goes into this?
I've never been able to figure out orbits for the 2 moons of Cindu.
