Weather in Apia in July

A good month. July is a solid month to be in Apia. You should expect rain on 16 days of the month, which is more days wet than dry.

Apia barely has seasons. July scores 68 out of 100 against a best of 72 in August — a gap small enough that the month you choose matters far less here than the week you choose.

This is persistent light rain rather than storms: 16 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. 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 — 1.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 29.3 °C and the coldest night fell to 23.4 °C, and the wettest single day dropped 44 mm — roughly 59% of the month's rain in one day.

July is moderately variable: 2 mm in the driest year against 198 mm in the wettest, around an average of 75 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind sits around 19.3 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 July sits in the year

Temperatures hold steady either side: 28.3 °C in June, 27.9 here, 28 in August. Nothing about the timing within the month matters much.

Daylight in July

Apia sits close enough to the equator that daylight barely moves all year — 11.4 hours in July, against a range of just 1.6 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 28.1 °C in July — warm enough that the water offers no relief from the heat. The sea peaks at 29.5 °C in March and bottoms out at 27.8 °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, September 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 Apia versus nearby

If Apia is one option among several, the nearby comparison is worth making. Nuku‘alofa is a better bet in July — 4.6 °C cooler, 3 days less rain. Avarua is a better bet in July — 4.1 °C cooler, 4 days less rain.

So: July is effectively as good as it gets here — 4 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
