Weather in Apia in June
Samoa · 20-year averages, June
Shoulder season. June sits in between. You will get good days and you will lose some. You should expect rain on 17 days of the month, which is more days wet than dry.
Apia barely has seasons. June scores 63 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: 17 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 28.3 °C days and 26.9 °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 June reaches 30 °C; the day barely swings — 1.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 29.7 °C and the coldest night fell to 24.5 °C, and the wettest single day dropped 62 mm — roughly 68% of the month's rain in one day.
June is moderately variable: 21 mm in the driest year against 221 mm in the wettest, around an average of 91 mm. Roughly two Junes in three land near that average, and the third does something else entirely.
Wind sits around 19 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 81%, high enough to notice on the warm days without dominating them.
How June sits in the year
Temperatures hold steady either side: 28.7 °C in May, 28.3 here, 27.9 in July. Nothing about the timing within the month matters much.
Daylight in June
Apia sits close enough to the equator that daylight barely moves all year — 11.3 hours in June, 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 28.6 °C in June — 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
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
June in Apia versus nearby
If Apia is one option among several, the nearby comparison is worth making. Nuku‘alofa is a better bet in June — 4.1 °C cooler, 4 days less rain. Avarua is a better bet in June — 3.8 °C cooler, 6 days less rain.
So: June works, with August the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
