Overview

About Pemba

Pemba is the northern island of the Zanzibar archipelago, about 50 kilometres from Unguja, and it is a very different proposition: greener, hillier, far less visited and almost entirely without the resort development that lines its neighbour’s coasts.

The Arabs called it Al Jazeera Al Khadra, the Green Island, and the name still fits. Clove plantations cover the interior hills, and Pemba produces the bulk of Zanzibar’s cloves, historically the source of the archipelago’s wealth and still a mainstay of the rural economy.

For visitors the draw is twofold. The Pemba Channel between the island and the mainland drops away steeply to great depth, creating wall dives with strong nutrient flow and correspondingly abundant marine life, rated among the finest in the Indian Ocean.

The second draw is simply how quiet it is. Tourism remains a small part of daily life, accommodation is limited to a handful of lodges, and the island’s Swahili ruins, mangrove creeks and forest reserve see almost no visitors at all.

People and culture

People and culture

Pemba is more conservative and more traditional than Unguja, and visitors are noticed rather than absorbed. Modest dress away from the beaches matters more here than on the main island, and a greeting in Swahili is genuinely appreciated rather than merely polite.

The island has a long-standing reputation across East Africa for traditional medicine and spiritual practice, and people travel from the mainland and beyond to consult healers here. That reputation is taken seriously locally and is not something to treat as a curiosity.

Ruins at Ras Mkumbuu, Chwaka and Pujini record Swahili settlements dating back to the tenth century, when this coast was part of a trading world connecting the African interior with Arabia, Persia, India and China. Ras Mkumbuu's mosque and tombs are the most substantial.

Clove harvesting dominates the agricultural calendar, and during the picking seasons the smell of drying cloves carries across the whole island. Visits to plantations are easily arranged and give a clear picture of how the island's economy still works.

Getting there

How to get there

By Air

Pemba's airport at Chake Chake receives daily flights from Zanzibar's Stone Town, around thirty minutes, and from Dar es Salaam and Tanga. Flying is how nearly all visitors arrive.

By Sea

Ferries run from Zanzibar and from Tanga on the mainland, but crossings are long, schedules unreliable and the Pemba Channel can be rough. Most travellers treat the ferry as a fallback rather than a plan.

Weather

Weather and climate in Pemba

Pemba shares the tropical maritime climate of the wider archipelago but is noticeably wetter and greener than Unguja, catching more rain across its hilly interior. Days run between 28°C and 32°C with nights around 21°C to 24°C, and humidity is high throughout the year.

The long rains fall from late March into May, with April the wettest by a clear margin, often exceeding 300 millimetres. Because Pemba has fewer sealed roads, the practical effect is greater: interior tracks become difficult, and the few lodges that stay open do so with reduced services.

The short rains of November and December arrive as sharp afternoon showers rather than sustained downpours. The island stays green year-round as a result of its higher overall rainfall, which is why the clove plantations thrive here.

June to October is the driest and most comfortable stretch, cooled by the monsoon winds. Water temperatures stay between 25°C and 29°C year-round, so a shorty wetsuit is ample whenever you dive.

Pack reef-safe sun protection, light layers and shoes you do not mind soaking on the boat.

Best time to go

Best time to visit Pemba

Best months
Jan–Feb, Jun–Oct, Dec

Pemba is a diving destination first and a beach destination second, so the calendar is driven by what the water is doing rather than by conditions ashore.

June to October is the main season, with dry weather, lower humidity and reliable conditions in the Pemba Channel. This is when the island's few lodges are busiest, which on Pemba still means quiet by any normal measure.

January to March brings the calmest, clearest water of the year and is the period serious divers choose. Visibility on the channel walls can exceed thirty metres. The trade-off is heat and heavy humidity ashore.

April and May should be avoided. The long rains are heavy, the channel is rough, visibility drops sharply and most dive operations close along with several lodges.

November and December occupy a middle ground: short showers, warm water, fewer visitors and lower rates.

Whichever season you choose, book ahead regardless, since total accommodation capacity across the whole island is very limited and moving between lodges mid-stay is impractical given the state of the roads.

Safety

Safety and security

Standard precautions apply. Travel with a licensed guide, keep valuables secured, and follow local advice on where and when it is sensible to walk. Roads deteriorate during the rains and night driving is best avoided throughout the region.

Where wildlife is present, remain in your vehicle outside designated areas and keep a respectful distance from all large animals. Water safety matters on the coast and the lakes: check conditions locally before swimming, and be aware of currents and tides.

Health precautions

Malaria is present across this region, so prophylaxis is advised and repellent should be used at dawn and dusk. Consult a travel clinic six to eight weeks before departure about yellow fever, typhoid, hepatitis A and B and tetanus.

Do not drink tap water untreated. Medical facilities vary considerably by location and are limited outside the larger towns, so travel with insurance that covers emergency evacuation and carry any prescription medication in your hand luggage.

FAQ

Frequently asked questions

How is Pemba different from Zanzibar's main island?

Pemba is greener, hillier, considerably less developed and far quieter. Where Unguja has resort strips along much of its coast, Pemba has a handful of lodges and an economy still built on cloves and fishing rather than tourism. It is also more conservative socially. Visitors who want beach nightlife and a choice of restaurants should stay on Unguja; those who want diving and genuine quiet should come here. Accommodation is limited, so booking ahead matters much more.

Why is Pemba known for diving?

The Pemba Channel between the island and the mainland drops away steeply to great depth, creating dramatic wall dives with strong nutrient flow and correspondingly abundant marine life. Visibility regularly exceeds thirty metres in the calm months, and sites around Misali Island and Manta Point are rated among the finest in the Indian Ocean. Currents can be strong on the channel walls, so several sites suit experienced divers better than those still building hours.

How do I get to Pemba?

Almost everyone flies. Daily services connect Chake Chake airport with Stone Town on Zanzibar in about thirty minutes, and there are also flights from Dar es Salaam and Tanga. Ferries run from Zanzibar and Tanga but the crossings are long, the schedules unreliable and the channel can be rough, so most visitors treat the boat as a fallback rather than a plan. Most lodges arrange airport transfers as part of a booking.

When should I visit Pemba?

June to October is the main season, dry and comfortable with reliable diving conditions. January to March brings the calmest and clearest water of the year and is what serious divers usually choose, at the cost of considerable heat and humidity ashore. April and May are best avoided entirely, as the long rains are heavy, the channel is rough and most dive operations and several lodges close for the season.

What is Misali Island?

Misali is a small uninhabited island west of Chake Chake, protected as a marine conservation area and the focus of much of Pemba's diving. Its reefs are in good condition, green turtles nest on its beaches, and the surrounding waters hold an unusual density of fish. Day trips run from the main island by boat, combining diving or snorkelling with time on the sand, and conservation fees paid on landing support local management.

Is there anything to do on Pemba besides diving?

Yes, though diving is what brings most visitors. The Ngezi Forest Reserve in the north protects remnant indigenous forest and the endemic Pemba flying fox. The Swahili ruins at Ras Mkumbuu include a tenth-century mosque and tombs. Clove plantation visits explain the island's economy, and kayaking the sheltered eastern mangrove creeks is a gentle alternative to the open sea. Kayaking the sheltered eastern mangrove creeks is a gentle alternative to the open sea, and the island's interior hills reward a slow drive with almost no other traffic on the road.

How many nights should I stay?

Four to seven nights suits most visitors, and divers should allow at least five to make the journey worthwhile given how few flights connect the island. Because accommodation is so limited and spread out, moving between lodges mid-stay is impractical, so choose one base and stay put. Pemba combines naturally with a few nights in Stone Town on Unguja at either end of a trip. Pemba combines naturally with a few nights in Stone Town on Unguja at either end of a trip.

Is Pemba suitable for families?

It can be, but with caveats. The lodges are small and geared toward divers and couples rather than children, activities for non-divers are limited, and medical facilities on the island are basic. Families wanting beach time with more infrastructure are far better served on Unguja. Older children who dive or snorkel confidently, however, will find Pemba's reefs exceptional and its quiet a genuine novelty.
