The same beach, twice a day
A Zanzibar beach is not one place. On much of the island the sea withdraws a long way at low water and returns at high, and the beach in the photograph you booked from exists for part of the day rather than all of it. This is not a defect and it is not a secret. It is the single most useful thing to understand before choosing where to spend a day, and it is the thing most beach lists leave out entirely, because a list of names cannot express it.
The practical version: ask what a beach is like at low tide, not what it looks like in the picture. The picture was taken at high tide. They always are.
The coasts, and what each is for
The north tip — Nungwi and Kendwa. The tide moves least here, which is why it is the default answer for anyone whose holiday is mostly swimming. It is also the busiest part of the island’s coastline, and busy is part of the product rather than a flaw in it. Our Nungwi area guide sets out what that trade actually buys.
The east and south-east — Paje, Jambiani, Bwejuu, Michamvi. A wide, shallow lagoon behind a reef. At low water it becomes flats you can walk far out onto; at high water it fills. This is the coast the kite schools are on, for exactly that reason, and it is the coast where “I’ll just go for a swim” is a question with a timetable attached. See the Paje area guide, and, if you are choosing between the two coasts, Nungwi or Paje, which is the same decision written as a comparison.
The south-west and the Stone Town side. Closest to the airport and to the town, and the least beach-led part of the island: this is where you stay if the town is the point and the sea is the background. Sunset here faces the right way, which the east coast does not.
A note that belongs here rather than in a box at the bottom: a large tidal range and a shallow reef lagoon mean water moves a long way and quickly, and most beaches have no lifeguard. That is the hazard we would put first for any visitor, and it is covered in is Zanzibar safe, which splits that question into the parts that can actually be answered.
The offshore sandbanks. Not a coast at all — bars of sand that surface at low tide and are gone at high, reached by boat. They are the most photographed “beach” in Zanzibar and the least permanent. What one costs to reach, and who actually runs the best-known trip to them, is on the Safari Blue page.
The measurement we have, and the one we do not
We hold a published tidal measurement for the east coast — taken at Chwaka Bay, not at Paje, and reported that way on the Paje area guide rather than rounded into a local figure it is not.
For the north tip we hold no published measurement at all. “Barely a tide at Nungwi” is a claim every guide to the island repeats, ours included, and on our own evidence that is repetition rather than a source. We have not attached a number to it, because a number would read better than the truth. It is logged as an open question, and any specific figure you see quoted for Nungwi — on any site — is worth treating as unsourced until someone shows you the measurement behind it.
So the difference between the coasts is real in kind and, for one of them, unmeasured in degree. That is a less satisfying sentence than a table would be. It is the one we can stand behind.
Seaweed, and what you are looking at
On the east coast the low-tide flats are farmed. The lines of rope and the low green growth that appear as the water goes out are seaweed cultivation, largely worked by women from the villages behind the beach, and it has been one of the coast’s steadier sources of income for decades. Some visitors read it as neglect of a beach. It is the opposite: it is the beach being used.
Resorts vary in how much they clear in front of their own frontage, which is a matter to ask about before booking rather than to discover afterwards — and it is a question about a specific property, not about a coast.
What we will not publish about beaches
We do not rank them. We do not use “best”, because it carries no source and no method. And we will not recommend a beach on the strength of a property that happens to sit on it until we hold that property’s published rates with a date, know what its kitchen actually does about vegetarian, Jain and halal preparation, and can state whether we earn a commission on it. That work is not finished. Until it is, the honest page is this one.
The method behind every figure we do publish is how we price; the gaps are in open questions; the mistakes are in corrections.
FAQ
When is the tide out in Zanzibar?
It varies by day and by coast, and it moves through the calendar rather than sitting at a fixed hour. Published tide tables for Zanzibar are harder to obtain than you would expect, which is why we have not put a schedule on this page — the gap is recorded in our open questions register. Ask your property for the week you are actually there.
Which Zanzibar beach can you swim at all day?
The north tip is the usual answer, and it is the answer we would give — with the caveat that we hold no published tidal measurement for Nungwi and are therefore describing a difference in kind rather than one we can quantify. The east and south-east coasts have a large tidal range and a shallow lagoon, so swimming there follows the water.
Is the seaweed on the beach a problem?
It is a crop. On the east coast the low-tide flats are farmed for seaweed by people from the villages behind the beach. How much of it sits in front of any particular hotel is a question for that hotel, not for the coast.
