Weather in Zanzibar in August
August in Zanzibar is a hot month. Plan the serious walking for morning. The rest of the day wants shade and a slower pace.
In Tanzania, this is how Zanzibar actually wears August, not how a country centroid would. August is winter in the southern year. A northern summer packing list is the wrong brief for Zanzibar. August is the cold side of the year in Zanzibar. Pack for that, not for a leftover summer photo.

What to expect
Daytime
Hot days in Zanzibar. Ruins, markets and hills are a morning job. Midday sightseeing is how people remember August for the wrong reason.
Nights stay warm. Air-con, if you can get it, is part of the brief. A jumper for August in Zanzibar is almost always a waste of bag space.
Rain
Rain is not the story in Zanzibar in August. Pack for sun. A shower would be news, not a plan.
Do not build the trip around weather windows. Build it around shade if it is hot, and around getting outside if it is not.
Evening
Evenings stay warm.
What to pack
