Sea Kayaking and Paddleboarding in Tanzania

What paddling on this coast is

Sea kayaking and paddleboarding in Tanzania are quiet-water activities, and that is not a limitation so much as the point. This is not a surf coast or an expedition coast. It is a coast of sheltered lagoons behind reef, of tidal creeks running into mangrove, of small islands within sight of each other, and of bays that go flat for months at a time.

The result is that a beginner can have a genuinely good hour here with very little instruction, and that a competent paddler can cover real distance between islands on the right day. What both need to understand first is the tide and the wind, because between them they decide whether a paddle is a pleasure or a problem.

Paddling also fills the gap in other people's holidays. It is what works on a windless day that kills a kite session, and it is the quietest way into a mangrove creek.

This coast sits beside Tanzania's safari country rather than inside it, though the lake paddling further inland genuinely does sit alongside the western and southern circuits.

Where sea kayaking works

Chole Bay on Mafia is arguably the best sea kayaking water in the country. It is a large, sheltered, shallow bay inside a marine park, ringed by reef and mangrove, with Chole and Juani islands a short crossing away and enough shoreline to paddle for days. It stays workable in weather that closes the open coast.

Menai Bay, off Fumba and the south-west of Unguja, is the other standout: a big protected bay with islands, sandbanks and mangrove creeks, and considerably less boat traffic than the north of the island. Chwaka Bay, on the east side, is similar in character and quieter still.

On the east coast lagoons, from Matemwe down through Paje and Jambiani, paddling works at high water and becomes impossible as the flat drains. In the north, around Nungwi and Kendwa, there is water at any tide but more boats and more open sea.

Pemba's deeply indented west coast, with its creeks, inlets and mangrove, is superb paddling water with almost nothing organised on it. On the mainland, the Wami river mouth inside Saadani, the river and creeks at Pangani, the channels at Kilwa and the island water off Dar es Salaam all paddle well.

Tide and wind, which decide everything

The tide here is semidiurnal, with a range from roughly a metre at the neaps to over three metres at the springs, and it does two things to a paddler.

It decides whether there is water. On a reef flat, the difference between high and low is the difference between a lagoon and a mudflat, and a kayak that set off comfortably can find itself being dragged. It also decides which way you are going: in creek mouths and the gaps that drain a lagoon, the tidal stream can be stronger than you can paddle against. The standard planning rule is to go out against the stream and come back with it, so that the tired half of the trip is the assisted half.

Wind is the more dangerous of the two. The prevailing winds on this coast are the north-easterly kaskazi from roughly December to March and the stronger south-easterly kusi from roughly June to September, and on the east coast both arrive side-onshore, which is forgiving. What is not forgiving is an offshore breeze, and it does happen, particularly in the early morning and on the west-facing coasts. Wind and rainfall run on separate calendars on this coast, and the islands' two wet seasons are the ones that decide when operations close.

An offshore wind is the single most serious hazard in this activity, and the reason is that it does not feel dangerous. The water in the lee of the land is flat, the paddling out is easy, and the trouble only becomes apparent on the way back, by which point you are tired, further out than you meant to be, and making no progress. A kayak has a great deal of windage and very little power. Check the wind direction before launching and do not go out on an offshore breeze, however pleasant it looks.

Paddling the mangrove creeks

This is the best thing you can do with a kayak on this coast. A creek at high water is silent, shaded, roofed by the trees and full of birds, and a boat with an engine changes all of that. Kingfishers, herons, crabs on the roots, and the occasional monitor lizard sliding off a branch.

The constraint is the tide, and it is strict: a creek that is navigable an hour either side of high water is mud at low. Getting the timing wrong means either a long wait or a long drag. Go with somebody who knows the channels the first time, because a mangrove system at falling tide is a maze in which every direction looks identical.

Chwaka Bay and Menai Bay on Unguja, the Pemba creeks, the Wami at Saadani and the Pangani river all give creek paddling. The forest itself, and what is in it, is covered in the mangrove guide.

Stand-up paddleboarding

Paddleboards have spread along this coast faster than kayaks, partly because they stow more easily and partly because the east-coast lagoons at high water are close to perfect for them: warm, flat, shallow enough to stand up in when you fall off, and large enough to go somewhere.

Two differences from a kayak matter. A board catches far more wind relative to its speed, so the offshore-wind problem is worse rather than better, and a modest breeze that a kayaker would shrug at will blow a standing paddler downwind steadily. And a board is much harder work in any chop, which on this coast means the lagoons are the place and the open coast generally is not.

For a beginner, a wide inflatable board on flat water at high tide in a sheltered lagoon is about as gentle an introduction to a watersport as exists. Kneeling rather than standing solves most of the balance and most of the wind problem at once. A leash is not optional: a board separated from its rider moves downwind faster than a person can swim.

Lake kayaking

Tanzania's great lakes offer paddling that is completely unlike the coast, and two of the finest shorelines in Africa for it.

Lake Tanganyika, particularly along the Mahale shore, combines extraordinarily clear water with forested mountains dropping straight to the beach. Lake Nyasa at Matema has sand beaches and a mountain backdrop. Lake Victoria, from Mwanza and the island parks, has rock formations and bays.

Three things make lake paddling a different decision from sea paddling.

Schistosomiasis. Paddling means getting wet, and this is fresh water. The United States Centers for Disease Control names only two safe categories in countries where the parasite is transmitted: the sea and chlorinated swimming pools. Its description of transmission includes streams and rivers, not only still water, and the widely repeated idea that fast-flowing water is safe has no backing from either CDC or the World Health Organization. All three lakes have produced documented infections in visitors. This does not make paddling impossible, but it makes it a health decision to take with a travel health professional rather than with a hotel. The wider position is in the beach holidays guide.

Crocodiles and hippos. Both occur, concentrated in vegetated shallows, river mouths and bays rather than open rocky shore. Here local knowledge genuinely does settle the question, and it should be asked for and followed.

Weather. Tanganyika and Victoria are large enough to build a serious sea very quickly, and afternoon squalls on both are sudden. Paddle early, stay close in, and do not cross open water on a lake you do not know.

Safety

The rules are short and they are the ones people skip.

• Check the wind direction before you launch, and do not go out on an offshore breeze.
• Check the tide, and plan to come back on the assisting stream rather than against it.
• Wear a buoyancy aid. The water is warm and that is precisely why people do not bother.
• Use a leash on a paddleboard, always.
• Tell someone where you are going and when you expect to be back.
• Carry water and take a phone in a dry pouch, and stay within reach of shore unless you are with a guide.
• Wear reef shoes for launching and landing, because sea urchins are everywhere on these flats.
• Stay clear of channel mouths and the gaps where a lagoon drains, where the stream runs hardest.

If you are blown offshore and cannot make ground, the standard advice is to stay with the craft, sit or lie on it to reduce windage, and signal. A kayak or board is visible and buoyant; a swimmer is neither.

What to take, and who this suits

Sun is the underestimated problem. A paddler is exposed for the whole trip with light coming off the water as well as the sky, and the tops of the feet, the backs of the hands and the underside of the chin are the places people get caught. A long-sleeved rash vest, a brimmed hat and sunglasses on a retainer.

Beyond that: water, a dry bag, reef shoes, and on a longer paddle something to eat. Binoculars if birds are part of the appeal, which in the creeks they should be.

The activity suits almost anyone who can swim and is reasonably mobile, and a sheltered lagoon paddle at high water is manageable for children with an adult alongside. It does not suit anyone unwilling to plan around the tide and the wind, because that is most of what makes it safe.
