Weather in Airlie Beach in August

Australia · 20-year averages, August

Prime time. If you get to pick your dates, August is the one. Highs average 24.2 °C, lows 17.4 °C, and rain falls on 3 days — nothing in the month is working against you.

August is the highest-scoring month of the twelve. The nearest rival is September, and the month at the other end of the year is January.

Rain falls on only 3 days, so an itinerary with no wet-weather fallback is a reasonable risk. 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 August reaches 30 °C. Across the twenty years measured, the hottest August day reached 29.8 °C and the coldest night fell to 10.1 °C, and the wettest single day dropped 34 mm — roughly 227% of the month's rain in one day.

This is the volatile part. August rainfall has ranged from 0 mm to 69 mm across the twenty years measured — a 69 mm spread around an average of 15 mm. The average is real but almost no individual August looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 8.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 69%.

How August sits in the year

Temperatures hold steady either side: 23.2 °C in July, 24.2 here, 26.3 in September. Nothing about the timing within the month matters much.

Daylight in August

August sits at the dark end of Airlie Beach's year — 11.4 hours of daylight against 13.3 at midsummer, gaining 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 23.1 °C in August — comfortable for a proper swim. The sea peaks at 28.6 °C in February and bottoms out at 23.1 °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.

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

August in Airlie Beach versus nearby

If Airlie Beach is one option among several, the nearby comparison is worth making. Mackay is close enough to be a coin toss — 2.3 °C cooler, the same number of rain days. Townsville is close enough to be a coin toss — 3 °C warmer, 1 day less rain.

So: August is the answer for Airlie Beach. If it is booked out or priced out, September is the next best thing at 0 points behind, and January is the month to keep off the shortlist.
