Weather in Port-Vila in July

A good month. July works. It is not the peak, but nothing about it fights you. Highs average 24.9 °C, lows 24 °C, and rain falls on 13 days — nothing in the month is working against you.

July ranks 2 of 12 in Port-Vila. Only September scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 13 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

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 July reaches 30 °C; the day barely swings — 0.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 27.2 °C and the coldest night fell to 21.5 °C, and the wettest single day dropped 54 mm — roughly 78% of the month's rain in one day.

July is moderately variable: 21 mm in the driest year against 176 mm in the wettest, around an average of 69 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind sits around 22.4 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 25.9 °C in June, 24.9 here, 24.8 in August. Nothing about the timing within the month matters much.

Daylight in July

July sits at the dark end of Port-Vila's year — 11.2 hours of daylight against 13.2 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 25.5 °C in July — warm enough to stay in as long as you like. The sea peaks at 28.8 °C in February and bottoms out at 25.2 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, October is the trade worth considering — 8 points weaker on weather, and materially quieter.

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

July in Port-Vila versus nearby

If Port-Vila is one option among several, the nearby comparison is worth making. Nouméa is close enough to be a coin toss — 3.1 °C cooler, 1 day less rain. Nadi is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: July is effectively as good as it gets here — 5 points behind September, which is inside the margin where the weather stops being the deciding factor and price starts being it.
