Like its air temperature, the sea temperature in Vanuatu remains pleasantly warm throughout the year.

Don't be too influenced by the labels "dry" and "wet" season; rainfall in Vanuatu is possible throughout the year. The islands receive an average of around 2,400 mm (94 in) of rain annually, with rain falling on roughly 140 days of the year.

As expected, the wet season (November to April) brings the heaviest rainfall, averaging between 170 to 300 mm (6.7 to 11.8 in) per month. This is also when tropical showers and occasional storms are more frequent.

During the dry season (May to October), Vanuatu still experiences some rain, with monthly totals ranging from 100 to 165 mm (4 to 6.5 in). While this period is drier and generally more settled, short, sudden showers can still occur, especially in the afternoons or evenings.

Thanks to the islands’ lush, volcanic terrain, inland and mountainous areas tend to get more rain than the coastal zones. Regional microclimates mean that if one village is wet, it might be sunny just a few kilometres away.

Vanuatu enjoys long daylight hours throughout the year, with around 13 hours of daylight per day from November to February. During the dry season (May to October), daylight is slightly shorter, ranging from 11 to 12 hours, with June having the shortest days.

In terms of sunshine, the sunniest months are typically from September to November, when Vanuatu sees an average of 8 hours of bright sunshine per day. Meanwhile, December and January are usually the cloudiest months, with rainfall more frequent and daily sunshine averaging around 7-8 hours.

Vanuatu, located in the South Pacific cyclone belt, is at risk of tropical cyclones during the wet season from November to April. The highest risk months are typically January to March, with the chance of stronger storms increasing during El Niño years.

The country has experienced several significant cyclones. Cyclone Pam (2015) caused widespread destruction across multiple islands, damaging homes, schools, and infrastructure. Cyclone Harold (2020) brought strong winds, flooding, and power outages, while smaller cyclones frequently affect parts of the archipelago with heavy rain and coastal surges.

Whilst severe cyclones/hurricanes are relatively rare, Vanuatu has well-established emergency response plans in place. For peace of mind, check forecasts regularly and read our Cyclone Safety in Vanuatu guide to stay prepared during cyclone season.

The year begins hot, humid, and rainy in Vanuatu, in the heart of the wet season and peak cyclone period. Expect frequent tropical showers, high humidity and the possibility of cyclones, keep an eye on weather alerts and follow local guidance if a storm approaches. Despite the wet conditions, the islands remain lively with New Year celebrations and often very few tourists, so you can enjoy the "Blue Holes" and "Champagne Beaches" all to yourself.

February remains hot and humid in Vanuatu, with frequent, intense afternoon showers. On the plus side, tradewinds are calmer this month, making it an excellent time for outrigger canoe tours, paddleboarding, kayaking and snorkelling between the stormy periods.

It’s still within the cyclone season, so keep an eye on local weather updates. The islands’ lush greenery and relatively low tourist numbers make it a peaceful time to explore waterfalls like the Rarru Cascades and Tufuntari Waterfall (except on cruise ship days).

March in Vanuatu continues to bring tropical warmth and high humidity. Rainfall remains frequent but may start to ease slightly compared to the earlier wet season months. Calm winds make it a great time for snorkelling, fishing and outrigger canoe tours. However, the wet season run-off means that visibility for scuba diving isn't always at its peak.

Tourist numbers are still low, so it’s perfect for exploring the "Blue Lagoon" and culture villages without the crowds getting in the way of your experience or photos. Unless, once more, it's cruise ship day.

If your trip coincides with Chief's Day in early March, you may be lucky to spot village celebrations as you travel around the islands.

April is the transitional month from the wet season to the dry season, still bringing some “April showers” along with it. Temperatures and humidity are still quite high, but at least it’s the last month of the cyclone season.

April is typically when Easter takes place, so expect some public holidays to close some shops and services.

May ushers in the dry season in Vanuatu. Rainfall decreases, the heat remains pleasant, and humidity begins to ease. Tradewinds start to pick up, and larger swells come in, making this a good time to start thinking about surfing.

The UV levels are also not quite as intense as in summer, averaging around a 8 UV index at midday. May is a good time to visit popular islands, like Efate and Santo, before the tourist crowds arrive.

June is also culturally significant in northern Vanuatu, particularly on Pentecost Island, where the Naghol (land diving) season begins. This centuries-old ritual, which inspired modern bungee jumping, draws both locals and visitors eager to witness the spectacle.

July sits firmly within Vanuatu’s dry season, bringing clear skies, low humidity and plenty of sunshine. Rainfall is minimal, making it one of the best months for hiking, cultural tours and exploring the outer islands. Days are warm without being oppressive, while evenings are noticeably cooler and comfortable.

The southeasterly tradewinds are well established by this time of year, which is great for sailing and kitesurfing, though they can create choppier conditions for swimming and snorkelling on exposed coasts. Sheltered lagoons and reef-protected beaches remain calm and inviting.

Average temperature: 26°C / 78.8°F (day), 23°C / 66.2°F (night)

August is one of the best months to visit Vanuatu, with dry, sunny weather and some of the lowest humidity levels of the year. Daytime temperatures are comfortably warm, while the southeasterly tradewinds provide a refreshing breeze that’s ideal for hiking, village visits and exploring cultural and historical sites.

Conditions for scuba diving are typically at their best with optimal visibility due to less surface run-off. Meanwhile, don't miss the Nalawan Festival in Southwest Malekula that hits Fire Beach in August.

As August falls within the peak travel season, it’s wise to book flights and accommodation well ahead of time.

September continues Vanuatu’s dry-season sweet spot, with low humidity, minimal rainfall and plenty of sunshine. Cooling coastal breezes keep daytime temperatures comfortable, making it an excellent month for sightseeing, hiking and cultural experiences. Sea conditions are generally good, especially in the mornings, although tradewinds can still create some chop later in the day.

Tourist numbers begin to ease compared to peak winter months, but local school holidays can bring a livelier atmosphere, especially at Vanuatu's largest music festival, Fest Napuan, offering a great chance to mingle with locals.

October marks the transition from Vanuatu’s dry season into the wetter months ahead. Daytime temperatures remain comfortably warm, while humidity begins to rise slightly and short, tropical showers become more common, usually in the afternoons rather than all day.

With around eight hours of sunshine daily and relatively few visitors, it’s still a rewarding time to travel.

Average temperature: 27°C / 80.6°F (day), 21°C / 69.8°F (night)

November signals the true start of Vanuatu’s wet season, bringing warmer temperatures, rising humidity and more frequent tropical showers. The tradewinds ease off, which often results in calmer seas, ideal for snorkelling, diving and lagoon cruises. While rain becomes more common, it usually falls in short, heavy bursts rather than all-day downpours, leaving plenty of time to explore between showers.

With the cyclone season approaching, it’s wise to keep an eye on weather forecasts, especially if you’re planning outer island travel. Note that the Unity Day public holiday is also in November.

Average temperature: 29°C / 84.2°F (day), 22°C / 71.6°F (night)

December sits firmly within Vanuatu’s wet season, bringing high heat, humidity and more frequent tropical downpours. Showers are often heavy but short-lived, and the lush landscapes are at their most vibrant. It’s also the heart of the festive period, with Christmas celebrations, church gatherings and festivals adding a unique island flavour to the holidays.

As cyclone season is well underway, it’s wise to stay informed with weather updates and allow flexibility in your travel plans. December is also a popular time for travel, so booking flights and accommodation early is recommended.
