Yes — October is one of the better months to visit Zanzibar. It sits at the tail end of the long dry season, with warm days near 30–31 °C (86–88 °F), sea temperatures around 26–27 °C (79–81 °F) and roughly 8–9 hours of sunshine a day. The short rains usually begin in the second half of October, so early in the month is reliably dry, while later weeks can bring brief, passing showers. Crowds are lighter than the July–August and Christmas peaks, and prices sit comfortably below high season.

The verdict: is October worth it?
For most travellers, October is a genuinely good time to come. It’s the last stretch of Zanzibar’s long dry season, so you still get the warm, sunny days the island is known for — but without the full weight of the July–August European rush or the December–January festive peak. That combination of reliable early-month sunshine, warm sea and thinner crowds is exactly why many repeat visitors quietly rate it.
The one honest caveat is timing within the month. October is a transition month: the short rains (locally, the vuli) typically start somewhere around the middle-to-late part of October and build through November. Early October behaves like classic dry season; the closing weeks can see short, passing showers. It’s not a wet month by Zanzibar standards, but it’s fair to expect the occasional downpour later on — usually brief, often overnight or in the afternoon, and rarely enough to derail a day.
Local tip
If dry, settled weather is your top priority, aim for the first half of October and you’ll rarely be disappointed. Travelling later in the month? Build in a little flexibility — we plan itineraries so beach and boat days can swap with Stone Town, spice farms or forest walks if a shower rolls through.
What is the weather like in Zanzibar in October?
October in Zanzibar is warm, sunny and humid, with daytime highs typically around 30–31 °C (86–88 °F) and nights easing to about 22–24 °C (72–75 °F). You can expect roughly 8–9 hours of sunshine a day, especially earlier in the month.
Rainfall is where October differs from mid-dry-season months like July and August. For much of the first half of the month it stays dry, but the short rains generally begin in the second half of October, so it’s normal to see a handful of rainy days — often brief showers rather than all-day rain. Humidity is moderate and creeps up as the month goes on and the rains approach.
Wind is generally light to moderate. October falls near the changeover between the south-easterly kusi winds of the dry season and the north-easterly kaskazi that follows, so breezes tend to ease compared with the reliably windy June–September stretch. That matters mainly for kitesurfers, who get more consistent wind earlier in the dry season than in October.
As with any tropical island, conditions vary year to year — the exact date the short rains arrive shifts, so it’s worth checking a forecast close to travel. What rarely changes is that October days are warm, largely sunny and comfortable for beach time and touring.
Daytime high~30–31 °C
Night low~22–24 °C
Sea temp~26–27 °C
Sunshine~8–9 hrs/day

Sea and beach conditions in October
The Indian Ocean around Zanzibar stays warm all year, and October is no exception — sea temperatures of roughly 26–27 °C (79–81 °F) mean you can swim comfortably without a wetsuit. For snorkelling and diving, water clarity is generally good, and it tends to be at its best earlier in the month before the first rains stir up run-off and sediment. Popular reef sites such as Mnemba Atoll generally show well in October, though visibility on any single day always depends on tide, wind and recent weather.
One thing first-time visitors are often surprised by is Zanzibar’s tides. The east coast — beaches like Paje and Jambiani — has a large tidal range, so at low tide the sea can retreat a long way across the reef flat, exposing seaweed farms and limiting swimming until the water returns. The north coast, around Nungwi and Kendwa, keeps deep water close to shore at almost any state of tide, which is why it’s the easiest choice for reliable, any-time swimming.
Local tip: plan around the tide, not just the clock
If you’re staying on the east coast, check the day’s tide times before booking a swim, snorkel or sandbank trip — the sea’s timetable matters more than the hour on your watch. Prefer to swim whenever you like? Base yourself in the north at Nungwi or Kendwa. We can line up boat trips to match the tide either way.
Is Zanzibar crowded in October?
October is a shoulder-season month, which is a big part of its appeal. The island’s busiest windows are July–August, when European summer holidays peak, and mid-December to January, over the festive season. October sits between them: beaches feel calmer, restaurants in Stone Town are easier, and popular excursions are less rushed than at peak times.
That said, “quieter” isn’t “empty.” October’s good weather still draws steady visitors, and late in the month some European half-term travellers arrive, so the most sought-after boat trips can fill on busy days. Booking the headline experiences — a Safari Blue day on the water or a Mnemba snorkelling trip — a few days ahead is sensible rather than essential.
Is October expensive? Costs and budget
October generally offers good value. Accommodation and flight prices tend to sit below the July–August and festive peaks, while still being a notch above the deepest low-season lull of April–May. In practical terms, you’re paying shoulder-season rates for near-high-season weather — one of the reasons the month is a favourite with value-minded travellers.
A few things influence what you’ll actually pay. Hotel demand rises for the most in-demand beachfront properties, so the best-value rooms book up first. Flight costs move with the season and can tick up around late-October half-term. Tour prices depend mostly on group size: our excursions are run privately for your party and priced per person on a sliding scale, so the per-head cost falls as your group grows. Because published prices change with the season, the most reliable figure is always a current quote.

Best things to do in Zanzibar in October
October’s warm sea and largely settled weather suit almost everything the island offers. These are the experiences that work especially well this month.
Snorkelling & dolphins at Mnemba
Warm water and generally good early-month visibility make Mnemba Atoll a highlight for snorkelling, and the calmer seas improve your odds of respectful dolphin encounters offshore.
Explore the Mnemba snorkelling tour →Safari Blue on the water
This full day of sailing, snorkelling, a sandbank stop and a seafood lunch is at its best when seas are calm — often the case on settled October days.
See the Safari Blue day trip →Jozani Forest & coral caves
A shaded, weather-proof choice: meet the endemic red colobus monkeys and cool off in a crystal-clear cave — ideal if a late-month shower passes through.
Discover Jozani Forest and the caves →Spice farm tour
Cooler than the peak-summer heat and easy to combine with Stone Town, a spice farm visit is a relaxed, sensory half-day that works in any October weather.
Book a spice farm tour →Stone Town, Prison Island & a sandbank
Explore the UNESCO old town, meet the giant tortoises on Prison Island and picnic on the Nakupenda sandbank — a classic combination in comfortable shoulder-season conditions.
See the Stone Town & sandbank tour →Add a mainland safari
October is a strong window for pairing the beach with a wildlife safari on the mainland, before the November rains arrive — an easy add-on to a Zanzibar trip.
Plan a safari from Zanzibar →Best beaches and areas in October
Every coast has its own character, and October rewards choosing the right base for how you like to spend your days.
- Nungwi & Kendwa (north): deep water close to shore at all tides, so swimming is easy any time; lively, with the widest choice of hotels, restaurants and sunset spots.
- Paje & Jambiani (east): long, photogenic beaches with a big tidal range; wonderful at high tide, and the traditional home of kitesurfing — though wind is less reliable in October than in the windier dry-season months.
- Matemwe (north-east): quieter and closest to Mnemba Atoll, ideal if snorkelling is your priority.
- Michamvi (south-east peninsula): calm, scenic and known for west-facing sunset views — a relaxed choice for couples.
- Stone Town: not a beach base, but the best hub for culture, history and easy access to most day tours.
Is October right for your kind of trip?
October suits a wide range of travellers. Here’s who tends to enjoy it most.
- Couples & honeymooners: warm, romantic and calmer than peak season, with better resort availability. See our Zanzibar honeymoon guide for pairing ideas.
- Families: with schools in session across much of the world for most of the month, beaches feel relaxed; late-October half-term brings a modest uptick.
- First-time visitors: reliable early-month weather and lighter crowds make October a forgiving introduction to the island.
- Divers & snorkellers: warm water and generally good visibility, best earlier in the month before the rains.
- Safari combiners: a strong month to add a mainland safari before the November rains.
- Value seekers: shoulder-season pricing with near-high-season weather.
October vs September vs November: which fits you?
The three months around October each have a distinct feel. If you’re still deciding, this quick comparison helps — and you can read the neighbours in full via our September guide and November guide.
| Month | Weather | Crowds | Prices | Best for |
|---|---|---|---|---|
| September | Dry, sunny, breezy; reliable | Moderate, easing from summer | Upper-shoulder | Diving, dependable sun |
| October | Warm & mostly dry; short rains build late | Shoulder; quieter than peak | Good value | Beaches, safari combos, all-rounders |

Frequently asked questions about Zanzibar in October
Is October a good time to visit Zanzibar?
Yes. October is the tail end of the long dry season, with warm, mostly sunny days, a warm sea for swimming and lighter crowds than the July–August and festive peaks. The main thing to know is that the short rains usually begin in the second half of the month, so early October is the driest, most settled window.
Does it rain in Zanzibar in October?
Some rain is likely, but October is not a wet month by Zanzibar standards. Much of the first half stays dry, while the short rains typically start in the second half — usually as brief showers, often overnight or in the afternoon, rather than all-day rain. Expect roughly seven to nine days with some rain across the month.
How hot is Zanzibar in October?
Daytime temperatures are typically around 30–31 °C (86–88 °F), cooling to about 22–24 °C (72–75 °F) at night. Humidity is moderate and rises toward the end of the month as the short rains approach, so it can feel warm and sticky at midday.
Is the sea warm enough to swim in October?
Yes — sea temperatures are around 26–27 °C (79–81 °F), warm enough to swim comfortably without a wetsuit. On the east coast, remember that the large tidal range can pull the water far out at low tide; the north coast around Nungwi and Kendwa stays swimmable at any tide.
Is October good for snorkelling and diving in Zanzibar?
It’s a good month, especially earlier on. The warm water and generally good visibility suit reef sites like Mnemba Atoll, though clarity on any given day depends on tide, wind and recent rain. Visibility tends to be best before the short rains arrive later in the month.
Is Zanzibar crowded in October?
Not especially. October is shoulder season, sitting between the July–August and December–January peaks, so beaches and Stone Town feel calmer and availability is good. Late-October half-term brings a modest rise, so it’s wise to book the most popular boat trips a few days ahead.
Is October a good time for a safari from Zanzibar?
Yes, October is a strong window to pair the beach with a mainland safari, generally offering good game viewing before the November rains. Exact conditions and wildlife movements vary year to year, so it’s worth planning the safari portion with an operator who tracks current conditions.
What should I pack for Zanzibar in October?
Pack light, breathable clothing, swimwear, strong reef-safe sunscreen, a hat and sunglasses. Add a light rain layer or compact umbrella for late-month showers, insect repellent, and modest clothing that covers shoulders and knees for Stone Town, spice farms and village visits.
