Weather in Port Douglas in June

Prime time. If you get to pick your dates, June is the one. Highs average 25.1 °C, lows 21.2 °C, and rain falls on 11 days — nothing in the month is working against you.

June ranks 4 of 12 in Port Douglas: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 11 days, 1 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 June reaches 30 °C; the day barely swings — 3.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 31.3 °C and the coldest night fell to 14.8 °C, and the wettest single day dropped 41 mm — roughly 76% of the month's rain in one day.

June is moderately variable: 5 mm in the driest year against 150 mm in the wettest, around an average of 54 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 10.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How June sits in the year

Temperatures hold steady either side: 26.1 °C in May, 25.1 here, 24.7 in July. Nothing about the timing within the month matters much.

Daylight in June

Port Douglas sits close enough to the equator that daylight barely moves all year — 11.2 hours in June, against a range of just 1.9 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 25.6 °C in June — warm enough to stay in as long as you like. The sea peaks at 29.2 °C in February and bottoms out at 24.7 °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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

June in Port Douglas versus nearby

If Port Douglas is one option among several, the nearby comparison is worth making. Cairns is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Townsville is a better bet in June — within a degree on temperature, 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.
