Weather in Airlie Beach in May

Prime time. May is about as good as Airlie Beach gets. Highs average 25.7 °C, lows 20.3 °C, and rain falls on 8 days — nothing in the month is working against you.

May ranks 5 of 12 in Airlie Beach: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 8 days, 0 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 May reaches 30 °C; the day barely swings — 5.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest May day reached 30.5 °C and the coldest night fell to 12.4 °C, and the wettest single day dropped 115 mm — roughly 319% of the month's rain in one day.

This is the volatile part. May rainfall has ranged from 4 mm to 152 mm across the twenty years measured — a 148 mm spread around an average of 36 mm. The average is real but almost no individual May looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 10 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.

How May sits in the year

The month is on the way down: 1.8 °C cooler than April, with June dropping another 1.8 °C. The first week and the last are not the same trip.

Daylight in May

May sits at the dark end of Airlie Beach's year — 11.2 hours of daylight against 13.3 at midsummer, losing 0.4 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 25.8 °C in May — warm enough to stay in as long as you like. 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

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.

May 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 — within a degree on temperature, 3 days more rain. Townsville is close enough to be a coin toss — 2.4 °C warmer, 3 days less rain.

So: May works, with August the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
