Weather in Port-Vila in January

Vanuatu · 20-year averages, January

Shoulder season. January is shoulder season in Port-Vila — cheaper, quieter, and a genuine gamble. You should expect rain on 20 days of the month, which is more days wet than dry.

January ranks 10 of 12 — near the bottom of Port-Vila's year. September is the month that works, and the swing between the two is 23 points, which is a different holiday rather than a slightly better one.

Rain on 20 of the month's 31 days, 7 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Pack for 28.1 °C days and 27.1 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average January reaches 30 °C; the day barely swings — 1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 30.2 °C and the coldest night fell to 24.8 °C, and the wettest single day dropped 113 mm — roughly 57% of the month's rain in one day.

January is moderately variable: 12 mm in the driest year against 396 mm in the wettest, around an average of 197 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind sits around 17.7 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How January sits in the year

Temperatures hold steady either side: 27.6 °C in December, 28.1 here, 28.5 in February. Nothing about the timing within the month matters much.

Daylight in January

January is at or near the longest days of Port-Vila's year: 13.1 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 28.3 °C in January — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

January in Port-Vila versus nearby

If Port-Vila is one option among several, the nearby comparison is worth making. Nouméa is a better bet in January — within a degree on temperature, 5 days less rain. Nadi is close enough to be a coin toss — within a degree on temperature, 3 days more rain.

So: January is a compromise. September is 21 points better and is what Port-Vila is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
