Is December a good time to visit Zanzibar?
Yes — December is one of Zanzibar’s best months to visit, with a caveat about timing. The first two weeks are the tail end of the short rains, so expect brief afternoon or evening showers between mostly sunny spells. From roughly mid-December the short dry season sets in: consistent sunshine, warm 25–30 °C days, sea temperatures around 28 °C, and calm, clear water good for snorkelling and diving. December is high season, and the Christmas–New Year fortnight is the busiest and most expensive window of the year, so early December offers the better balance of good weather and lower prices.
- Weather: 25–30 °C, drier after mid-month
- Sea temp: ~28 °C, warm for swimming
- Season: High season (peak over the holidays)
- Rainfall: ~134 mm, mostly early December
- Crowds: Busy; Christmas–New Year is peak
- Best for: Beaches, snorkelling, festive trips
If you are weighing up when to fly out, December is an easy month to recommend — but the trip you get depends heavily on which half of the month you travel and how far ahead you book. As a Stone Town–based operator running tours here since 2014, we plan dozens of December trips each year, and the questions travellers actually ask are practical ones: will it rain, is the sea warm, how crowded is it, and how much more does the festive season cost? This guide answers each in turn, then points you to the activities and beaches that suit December best. For the wider picture, see our month-by-month guide to the best time to visit Zanzibar.
Zanzibar weather in December
December is a transition month. It begins as the short rains (roughly November–December) fade out and ends firmly in the short dry season that runs into February. In practice, that means two slightly different halves.
In early December, expect warm, humid days interrupted by short showers — usually brief downpours in the afternoon or evening rather than all-day rain, leaving plenty of dry hours for the beach and tours. From mid-December onwards, the showers thin out, the skies clear, and sunshine becomes far more reliable through Christmas and New Year. Daytime temperatures sit around 25–30 °C and can touch 33 °C, with high humidity eased by coastal breezes. December also has some of the longest days of the year — close to 12.5 hours of daylight — which means more usable time for excursions.
| Weather aspect | What to expect in December |
|---|---|
| Temperature | 25–30 °C (77–86 °F), occasionally up to ~33 °C |
| Rainfall | ~134 mm total, concentrated in early December; brief showers |
| Humidity | High, eased by sea breezes on the coast |
| Sunshine | Increasingly reliable from mid-month; ~12.5 hrs daylight |
| Sea temperature | Around 28 °C — warm for swimming and snorkelling |
Weather figures are typical averages. Conditions vary year to year, and climate patterns can shift a shower earlier or later than the historical norm.
Sea, beaches and swimming conditions in December
Sea conditions in December are generally good and improve as the month dries out. The water is warm — around 28 °C — and underwater visibility is usually strong once the short rains ease, making the second half of the month especially good for snorkelling and diving. That said, conditions on any given day depend on location, tide, wind and recent rainfall, so it is worth planning water activities around the tide rather than assuming every site is calm at every hour.
The north coast — Nungwi and Kendwa — holds deeper water close to shore and stays swimmable across the tide, which makes it the most reliable choice for travellers who mainly want to swim. The east coast (Paje, Jambiani, Matemwe) has stronger tidal swings and, in December, steadier breeze that suits kitesurfers. If you want to combine snorkelling with calm, clear water, the reefs around Mnemba Atoll are at their best in the drier weeks.
How busy is Zanzibar in December?
December is high season, and it is not evenly busy. The first two to three weeks are comparatively calm — a genuine sweet spot of improving weather and pre-holiday prices. From around 20 December to 2 January, demand peaks: this is the single busiest, most sought-after travel window in Zanzibar, driven by Christmas, New Year and school holidays across Europe and the Gulf.
What that means for you is simple: popular beach hotels, festive dinners and the most-booked excursions (Safari Blue, sunset cruises, private Stone Town–Prison Island–Nakupenda combinations) sell out well ahead over the holidays. If your dates fall in the festive fortnight, treat early booking as essential rather than optional. If your dates are flexible, the first half of December gives you most of the upside with far less pressure on availability and price.
What does Zanzibar cost in December?
December is the most price-sensitive month of the year, but the cost story is almost entirely about timing. Accommodation and international flights climb sharply through the Christmas–New Year window, when many hotels charge peak-season rates and some add compulsory festive gala dinners. Travel in early December, before roughly the 18th, and you will usually find noticeably lower room rates and better flight availability for very similar weather.
Tour and excursion prices are far less seasonal than hotels and flights. Our day tours are priced per person, private to your own party, and the per-person rate drops as your group grows. For orientation, here are typical starting prices for popular December activities:
| Activity | From (per person) | Why it suits December |
|---|---|---|
| Spice Farm Tour | $10 | Great on a short shower day; half-day, sheltered |
| Stone Town Tour | $17 | Culture-focused; ideal if early rain interrupts the beach |
| Sunset Dhow Cruise | $27 | Long, clear December evenings; strong for couples |
| Swimming with Dolphins | $27 | Calm early-morning seas; year-round at Kizimkazi |
| Nakupenda Sandbank | $60 | Sandbank picnic shines in the drier second half |
| Safari Blue | $60 | Full-day snorkel & sail; best in clear, calm weather |
Prices are per-person “from” rates for private-to-your-party tours and fall as group size increases. Luxury add-ons and large groups are quoted individually on WhatsApp.
Our advice: split the difference on dates
If you want festive atmosphere without festive prices, target 10–20 December. You get the drier, sunnier back half of the month, the decorations and build-up in Stone Town, and rates well below the 24 December–1 January peak. If the holiday itself is the point, book flights, hotel and your headline excursions two to three months ahead — festive-week capacity is the first thing to disappear.
Best things to do in Zanzibar in December
December suits both water-based days and cultural ones, which is useful early in the month when a short shower can reshuffle your plans. We match the activity to the conditions rather than sending everyone to the same beach.
- Best for snorkelling: the reefs at Mnemba Atoll and a full-day Safari Blue trip, both strongest once the water clears mid-month.
- Best for couples: a sunset dhow cruise makes the most of December’s long, clear evenings.
- Best for a rainy early-December morning: a spice farm tour or a walk through Stone Town — mostly sheltered and unaffected by a passing shower.
- Best for nature: Jozani Forest and its red colobus monkeys, an easy half-day that works in any December weather.
- Best for a mainland add-on: a wildlife safari from Zanzibar to Mikumi or the Serengeti pairs naturally with a beach week.
December also falls within the whale-shark season (roughly November–February) around the nearby Mafia Archipelago — a bucket-list sighting for divers willing to travel, and one to arrange only through operators that follow responsible-wildlife practices.
Browse all Zanzibar toursIs December good for the festive season?
It is one of the main reasons people come. Christmas and New Year in Zanzibar blend Swahili culture with a genuinely multicultural festive mood — beach barbecues, live music, seafood gala dinners and New Year’s Eve parties, particularly around Stone Town and the northern beaches. Because this is a large topic with its own booking timeline, we have covered it in depth separately: read our dedicated guide to Christmas and New Year in Zanzibar for what to book, when, and how to avoid the common festive-season mistakes.
Is December good for different types of travellers?
December works for most travellers, with a few timing notes:
- Couples and honeymooners: excellent — warm sea, long evenings and a festive mood — but book the holiday fortnight early, as the best romantic hotels fill first.
- Families: strong choice thanks to the school-holiday overlap and calm swimming at Nungwi and Kendwa; the flip side is that everyone else travels then too, so reserve early.
- First-time visitors: ideal all-rounder, especially in the drier second half.
- Beach and water lovers: the improving conditions and 28 °C sea make it one of the better months.
- Budget travellers: favour early December, or consider the lower-priced shoulder months in our November guide.
What to pack for Zanzibar in December
- Light, breathable clothing for warm, humid days
- A packable rain layer or small umbrella, mainly for early December
- Reef-safe sunscreen, sunglasses and a hat — UV is strong even on cloudy days
- Modest cover (shoulders and knees) for Stone Town and village visits
- Reef shoes for rocky entries and low-tide walks on the east coast
- Insect repellent for evenings
Local tip: plan water days around the tide
Sandbank trips like Nakupenda and east-coast swimming depend on the tide, not just the forecast. When you book with us, we schedule your snorkelling and sandbank days to the December tide tables so you arrive at the right state of water — a detail that quietly makes or breaks a trip here.

Frequently asked questions about visiting Zanzibar in December
Does it rain a lot in Zanzibar in December?
Not heavily. Early December carries the tail end of the short rains, so expect brief afternoon or evening showers rather than all-day rain — usually with plenty of dry hours around them. From about mid-December the showers thin out and sunshine becomes reliable through the holidays. Total rainfall for the month averages around 134 mm, most of it falling in the first two weeks.
Is the sea warm enough to swim in December?
Yes. Sea temperatures sit around 28 °C, which is comfortable for swimming, snorkelling and diving. Underwater visibility is generally good and improves as the month dries out, making the second half of December especially rewarding for reef trips. Conditions on the day still depend on tide, wind and location, so it helps to plan water activities around the tide.
Is Zanzibar crowded in December?
December is high season. The first two to three weeks are relatively calm, but the Christmas–New Year fortnight (roughly 20 December–2 January) is the busiest window of the year, driven by holidays across Europe and the Gulf. Hotels, festive dinners and popular excursions book out well ahead over that period, so early booking matters most if your dates fall in the holidays.
Is December expensive in Zanzibar?
It depends almost entirely on timing. Accommodation and flights peak over Christmas and New Year, when many hotels charge top-season rates and add festive gala dinners. Travel in early December, before around the 18th, and you will usually find noticeably lower prices for very similar weather. Day-tour prices are far less seasonal than hotels and flights.
When is the cheapest time to visit Zanzibar in December?
The first two weeks. Early December combines improving, drier weather with pre-holiday prices, before the sharp rise that begins around 20 December. If you want festive atmosphere without festive rates, aim for roughly 10–20 December, which gives you the sunnier back half of the month at well below peak prices.
Is December a good time for snorkelling and diving?
Yes, particularly in the second half of the month. As the short rains clear, the water warms to around 28 °C and visibility improves, making reefs such as Mnemba Atoll and full-day Safari Blue trips excellent. December also falls within the whale-shark season near the Mafia Archipelago, best arranged through responsible operators.
How does December compare to January in Zanzibar?
Both sit in the short dry season and are strong months. December is the transition — wetter early, then drying out, with the festive peak and its higher prices. January is hotter and fully dry, with excellent diving visibility and post-holiday demand that eases slightly after the first week. See our Zanzibar in January guide for the detail.
Should I book my December tours in advance?
For the Christmas–New Year period, yes — festive-week capacity on popular excursions such as Safari Blue, sunset cruises and private island combinations is the first to sell out. For early-December dates you have more flexibility, but booking a few weeks ahead still secures your preferred days and lets us schedule water activities around the tides.
The verdict: is December worth it?
For most travellers, yes. December delivers warm days, a 28 °C sea, long daylight hours and — after mid-month — reliable sunshine, alongside the best festive atmosphere of the year. The one trade-off is price and availability over Christmas and New Year, which is entirely manageable if you either travel in early December or book the holiday fortnight well ahead.
