Weather in Mackay in April
Australia · 20-year averages, April
A good month. April works. It is not the peak, but nothing about it fights you. Highs average 26.1 °C, lows 24.2 °C, and rain falls on 13 days — nothing in the month is working against you.
April ranks 8 of 12 in Mackay: past the worst of the year but short of August, which is the month to book if the dates are open.
Rain on 13 days, 2 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 April reaches 30 °C; the day barely swings — 1.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 29.7 °C and the coldest night fell to 18.3 °C, and the wettest single day dropped 82 mm — roughly 94% of the month's rain in one day.
April is moderately variable: 11 mm in the driest year against 192 mm in the wettest, around an average of 87 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.
Wind sits around 17 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 77%, high enough to notice on the warm days without dominating them.
How April sits in the year
Temperatures hold steady either side: 27.6 °C in March, 26.1 here, 24.2 in May. Nothing about the timing within the month matters much.
Daylight in April
11.6 hours of daylight, losing 0.6 hours across the month. That is between Mackay's extremes of 13.4 and 10.9 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 27.1 °C in April — warm enough that the water offers no relief from the heat. The sea peaks at 28.5 °C in February and bottoms out at 23 °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.
April in Mackay versus nearby
If Mackay is one option among several, the nearby comparison is worth making. Airlie Beach is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Rockhampton is close enough to be a coin toss — 2.7 °C warmer, 6 days less rain.
So: April is a compromise. August is 19 points better and is what Mackay is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
