Vanuatu Weather in January

January is one of the warmest months in Vanuatu, sitting squarely within the country’s tropical wet season. Daytime temperatures typically reach around 30°C (86°F), while nighttime lows average about 23°C (73°F). With high heat and humidity, conditions can feel warmer than the thermometer suggests, particularly during the middle of the day, making lightweight clothing and regular hydration essential.

Sea Temperature in January

The ocean around Vanuatu stays warm year-round, but January brings some of the warmest sea temperatures. On average, the sea sits at a balmy 28°C (82°F), perfect for swimming, snorkelling and other water activities.

If you’re hoping to catch some sun in Vanuatu in January, you’re still in for plenty of bright spells despite it being the wet season. The islands average around 7 hours of sunshine per day, giving you ample time to explore beaches, lagoons and lush inland landscapes.

That said, cloud cover and short, heavy rain showers are common, often passing quickly and followed by sunshine. January also enjoys long daylight hours, with roughly 13 hours of daylight each day.

UV Levels During January

UV levels in Vanuatu are extremely high in January, often reaching 11+ on the UV index around midday. It's important to wear reef-safe, high-SPF sunscreen, along with protective clothing and a hat if you're out in the sun for long periods. For advice on what sunscreen to wear, see The Best Sunscreens for Vanuatu + Sun Protection Tips.

Sunrise and Sunset in January

January has daylight hours lasting about 13 hours a day in Vanuatu.

• Sunrise: 5:23 am at the beginning of January and 5:41 am at the end of January
• Sunset: 6:27 pm at the beginning of January and 6:30 pm at the end of January.

January sits firmly in the heart of the wet season in Vanuatu and is one of the wetter months of the year. On average, the islands receive around 301 mm of rainfall, with roughly 19 days in the month seeing some form of precipitation. Humidity is high, and rain is a regular feature of daily weather patterns.

That said, rainfall in Vanuatu is often short, intense and tropical rather than constant drizzle. Heavy downpours tend to pass quickly, frequently giving way to sunshine or broken cloud cover. This rhythm still allows plenty of time for swimming, snorkelling and exploring, especially if you plan activities around the weather and stay flexible with your schedule.

• Efate (Port Vila) – The average rainfall in January is 301 mm (11.9 in)
• Espiritu Santo - The average rainfall in January is 334 mm (13 in)

January falls within the South Pacific cyclone season (November to April), meaning Vanuatu has a higher chance of tropical storms during this time. While a direct cyclone impact is unlikely for most travellers, periods of heavy rain, strong winds and rough seas can occur when systems pass nearby.

Vanuatu is one of the region’s more cyclone-exposed countries, as shown by past severe events such as Cyclone Pam (2015). To reduce risk, the dry season (May to October) is the safest time to visit, but travellers in January should stay alert to weather updates and follow local safety advice if warnings are issued.

If you want to avoid the risk of cyclones in Vanuatu, it’s best to travel in the dry season. For those planning to travel during January, be aware of what to do if there is a cyclone alert by following our guide, Cyclone Safety in Vanuatu.

One of the things we love about Vanuatu is that it never feels overwhelming. Even in January, you'll find it refreshingly uncrowded. That said, January is school holiday time for locals, so you might notice a bit more buzz around natural attractions and beaches.

While every island has its charms in January, Efate makes a great home base during this time of year, only becoming "busy" on cruise ship days. Being home to the capital, Port Vila, it's the most accessible island with the best range of accommodation, restaurants and transport options, most of which have availability unlike the more popular months of the year.

What's more, the wet season transforms the landscapes into something quite spectacular, making January perfect for chasing waterfalls like Mele Cascades and Rarru Cascades. To escape the rain, visit the islands of Pele, Nguna, Moso and Lelepa in what locals call the "dry pocket" of Efate. You'll love visiting pristine white beaches, snorkelling with giant clams and turtles, and the historical site of Chief Roi Mata's Domain.

Don't write off Vanuatu's outer islands just yet, though. If weather and transport align, Tanna is a standout choice for adventurous souls. We can't get enough of Mt Yasur, one of the world's most accessible active volcanoes. The rich kastom culture and dramatic landscapes there are simply unforgettable.
