Is October a Good Time for Zanzibar? An Honest 48-Year Take on Weather, Prices & Snorkeling

Our family has been sending guests to Zanzibar from Arusha since 1978, and October is one of the months we recommend most often. Travellers searching for Zanzibar in October usually want a straight answer: will the short rains spoil the beach? In practice, October is one of the island's best-value months if you plan around brief late-day showers — 18 to 22 sunny days, warm 25–27°C ocean water, Mnemba diving still in season, hotel rates 20–30% below the September peak, and complete 5-night beach extensions from about $700 per person before international flights. Mornings do most of the holiday work.

October Weather — The Short Rains in Context

October marks the arrival of the short rains — Zanzibar's second rainy season. But it is critical to understand what "short rains" means in practice. These are not the sustained, day-long downpours of the March–May long rains. They are typically intense, dramatic afternoon thundershowers: dark clouds build in the early afternoon, rain falls heavily for 30–90 minutes, and then the sky clears and the evening is often spectacular.

October rainfall averages 100–150mm for the month — spread across perhaps 8–12 rainy days, not continuous rain. On the days it does rain, the rain typically falls between 1pm and 4pm. You lose the afternoon. You keep the morning and the evening. Most days in October — perhaps 18–22 days — are completely dry and sunny.

The trade winds begin to ease in October as the southeast monsoon transitions toward the northeast monsoon that brings the short rains. This means the seas can be less flat than September, though they remain swimmable. The transition in ocean currents means the water temperature rises slightly — back to 25–27°C — as the cold southern currents ease.

The October Rhythm — How to Plan Your Days

The key to October is scheduling around the likely afternoon rain. Our recommendations for structuring an October Zanzibar trip:

Mornings (7am–1pm): Beach, swimming, snorkelling, dhow cruise. The mornings in October are often the most beautiful of the year — warm, calm, clear light. Mnemba snorkelling trips, dolphin tours to Kizimkazi, and beach time all work perfectly in the morning window.

Early afternoon (1–4pm): Cultural activities, lunch, relaxation. Stone Town exploration in the early afternoon works well — the rain keeps you indoors, and the atmosphere of the Old City in the rain is extraordinary. A long lunch at a Stone Town restaurant, reading on a covered terrace, or a visit to the Slave Market memorial and museum are ideal for the rainy window.

Late afternoon and evening (4pm onwards): The rain clears, the sky lights up, and the island re-emerges at its finest. Sundowners on a rooftop, dinner in a beach restaurant, a walk along the shore as the clouds break — October evenings are often the most beautiful of the year.

Diving in October — Excellent Conditions

October is one of the better months for diving despite the short rains. The diving conditions are still good: water clarity remains at 25–40m, and whale sharks are occasionally still encountered near Mnemba as the season winds down. The reefs at Mnemba, Matemwe, and Chumbe are in excellent condition.

What changes in October is the water temperature. As the cold southern currents begin to ease, the water warms slightly from September's lows. October water temperature is 25–27°C — the warmest since June, and comfortable with a 3mm wetsuit. For some divers, this warmer water is more pleasant than September's cooler temperatures.

October Safari Combo — Migration End and Shoulder Season

October is an interesting month for the Tanzania safari combination. The Great Migration is winding down — the crossings continue in early October but the herds are beginning to move south. By mid-October, the migration is largely concluded for the year. This means the Northern Circuit is transitioning into the shoulder season: less dramatic than September, but with excellent general wildlife viewing still available in the Serengeti and Ngorongoro.

For travellers who prioritise wildlife above all, October is not the ideal month. But for those whose interest is broader — wildlife plus beaches plus culture — October offers excellent value and a more relaxed pace than the peak months.

Beach by Beach — What October Is Actually Like on the Sand

Our family has put guests on every beach in Zanzibar for 48 years, and October is the month when the differences between them matter most. The umbrella "Zanzibar" page hides real day-to-day variation between the north, the east, and the south coasts. Here is what each coast actually feels like in October.

Nungwi & Kendwa (north coast) — the calmest choice

Nungwi and Kendwa are the two beaches we send most of our October guests to, and the reason is simple: they are the only beaches in Zanzibar that do not dry out at low tide. Every other coast retreats hundreds of metres on a falling tide — fine for long walks, poor for swimming. In October, when the morning calm matters most (because the afternoon may bring rain), Nungwi and Kendwa give you swim-anytime water. The southeast trade winds have eased in October, so the sea is flat most mornings — glassy, clear, snorkelling straight off the beach.

What October specifically means here: water temperature is rising back toward 27°C, the wind has dropped from August's peak, and visibility off the reef is 15–25m. There are no big international resort chains on Nungwi — it is a working fishing village with a strip of mid-range and boutique hotels. Sunsets face west over the smaller islands. If you want a calm, low-friction beach day, this is where to be.

Paje & Jambiani (east coast) — windier, dramatic skies

The east coast is the kite-surf coast — and October is when the wind is easing, which actually makes it interesting in two directions. The first two weeks of October can still carry August's stronger southeast trades, which is the best kite-surfing of the year. From mid-October the wind begins to swing, and by the third week it is intermittent enough that first-time kiters have a learning window they don't get in August.

But Paje and Jambiani are also where October's short rains are most photogenic. The afternoon clouds build over the inland baobab forest and roll in off the water — long horizontal cloud formations, vivid sunsets behind them, the smell of rain on hot sand. The tides on the east coast retreat 600m–1km on a low spring tide, so beach-walking is the activity, not swimming. We recommend a 4WD if you are staying on the east coast in October — the access roads to the smaller hotels turn to mud after a heavy shower.

Matemwe, Pwani, & the Mnemba reef (northeast) — for divers

The northeast coast is where Zanzibar's best diving lives — Mnemba Atoll is the headline site, but Leven Bank, Chumbe, and the inner reefs around Matemwe are equally good and less dived. October is the last reliably strong month for the Mnemba dive season before the November transition. Visibility is still 25–35m most days, water temperature is 25–27°C, and whale sharks — though no longer guaranteed — are reported on roughly one in three October dive days.

The northeast beaches themselves are quieter than Nungwi, with smaller boutique lodges and the working-village rhythm of Matemwe and Pwani Mchangani. The reef is the draw, not the sand. If you are coming to Zanzibar primarily to dive and you can pick any month, October is the answer.

Stone Town — the half-day we always build into October trips

Stone Town is the historic quarter of Zanzibar City, a UNESCO World Heritage Site of narrow alleys, carved wooden doors, Persian-bath architecture, the old slave market, and the Forodhani night-food gardens. It is on every Zanzibar itinerary for a reason — and in October, when the afternoon rains reliably arrive between 1pm and 4pm, Stone Town is exactly where you want to be.

We build Stone Town into October trips as a half-day on arrival or before departure. The morning walk is the spine of it: the House of Wonders, the Old Fort, the Slave Market memorial, the Anglican Cathedral, the central market for spices, and the rooftop of the Africa House hotel for a tea looking over the harbour. Most of this is indoors or under awning, so a 1pm–3pm thundershower interrupts very little. The Forodhani Gardens sea-food barbecue comes alive at sunset — try the Zanzibar pizza, the lobster, the sugar-cane juice — and it is the most economical evening meal on the island.

Two practical notes from our October operations: book a Stone Town guide through your hotel (USD 20–30 for a half-day) rather than the freelance touts at the dock; and if you are staying on the north or east coast, plan Stone Town on your arrival or departure day because the drive back in heavy rain is slow and visibility is poor on the unlit roads after dark.

Getting There — Flight or Ferry?

Most travellers arrive in Zanzibar by air — Zanzibar International Airport (ZNZ) has direct flights from Dar es Salaam (multiple daily, 20 minutes), Arusha (2–3 daily, 1h 30m), Nairobi (4–5 daily, 1h 30m), and a growing list of European gateways via Addis Ababa, Doha, or Istanbul. From your safari's end point in the Northern Circuit (Arusha or Manyara), the standard arrangement is a 1h 30m domestic flight directly into Zanzibar — bookable through us at the same time as your safari and usually bundled into the trip price.

The ferry from Dar es Salaam is the alternative and it is genuinely interesting for travellers who want to feel the sea crossing — the modern MV Mapenduzi and sister vessels take 2h–2h 15m, depart from the Kigamboni terminal (south of Dar city centre, allow 45 minutes from the international airport), and run several times a day. Tickets are USD 35–50 per person one-way, payable in cash at the terminal. The boats are air-conditioned and stable — they do not pitch — and the sea is usually calm in October.

When we recommend the ferry vs flight: the flight if your safari ended at a northern airstrip and you have one or two nights in Zanzibar; the ferry if you have come in overland from Dar, want to experience the channel, and are not time-pressed. We do not recommend the ferry in March–May (the long-rains seas can be rough), and we do not recommend it after dark on your departure day (the last return boat is 16:00, and an evening flight is far easier).

Combining With the Northern-Circuit Safari — What Actually Works in October

October is a transitional month for the safari half of a Tanzania trip. The Great Migration crossings are ending in the first half of the month (the last herds move out of the Mara River area by mid-October), and the dry-season game viewing that makes September excellent begins to soften. But this is not a negative — it just means the safari half of an October trip rewards a different itinerary than the July–September peak.

Our standard October 9-day combination, which we have refined across 48 years of family operation, runs as follows. Days 1–4: Tarangire (elephants in huge herds, baobab-studded landscape, fewer vehicles than Serengeti) plus a night at the Ngorongoro Crater rim. Days 5–6: two nights in the Central Serengeti for general wildlife — lion prides, leopard in the Seronera valley, cheetah on the short-grass plains. Days 7–9: fly Manyara to Zanzibar, transfer to the north coast, three nights beach.

What this itinerary gives you that a Serengeti-only October plan does not: Tarangire in October is excellent (the dry-season concentrations are at their tightest, the Tarangire River is the only permanent water for many miles), and the safari closes on the Crater — which has reliable wildlife year-round — before the beach relaxation. The Serengeti in October is not the spectacle it is in July–September, but the safari has the rare advantage of being uncrowded: vehicles are few, lodges offer shoulder-season rates (15–25% below September), and the light in October is softer than the high-sun glare of mid-summer.

Price for a private October 9-day for two travellers sharing: from USD 5,800 per person in mid-range accommodation (a Tarangire-tented lodge, a Crater-rim lodge, a Central Serengeti camp, and a Kendwa or Nungwi beach hotel — equivalents vary by availability); USD 8,200–10,500 per person at the upper-mid range; USD 12,000+ per person at the luxury tier (premium Tarangire lodge, Crater-rim suite with floor-to-ceiling views, a private-conservancy Serengeti camp, and a luxury north-coast villa). Domestic flights into and out of Zanzibar are bundled into all three tiers.

October Costs — Best Value in the High Season Window

October prices are 20–30% below the September peak — genuine value within the high-season window. This is the single best-value month in the September–November period.

Mid-range beachfront rooms: $70–130 per night. Luxury resorts: $250–450 per night. Significant savings versus September, with only marginally different weather (the short rains versus the fully dry conditions of September).

A complete 5-night Zanzibar extension in October — mid-range accommodation, spice tour, diving day, and transfers — costs $700–1,200 per person. At luxury level: $1,500–2,500 per person.

Our Verdict — October

October is the traveller's month for Zanzibar. If you are comfortable with brief afternoon showers and want the best combination of good weather, excellent diving, and genuine value, October is outstanding. You sacrifice nothing in experience quality — and you gain meaningfully in price and space.

The short rains are a modest disruption, not a significant problem. Most days are fine, and the rain that does fall is typically predictable and short. The dramatic skies that the short rains produce — extraordinary cloud formations, vivid sunsets, the smell of rain on hot sand — are a photographer's delight.
