Weather in Townsville in April

A good month. April works. It is not the peak, but nothing about it fights you. Highs average 30 °C, lows 21.6 °C, and rain falls on 7 days — nothing in the month is working against you.

April ranks 6 of 12 in Townsville: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 7 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 30 °C days and 21.6 °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: 16 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest April day reached 35.2 °C and the coldest night fell to 13.3 °C, and the wettest single day dropped 74 mm — roughly 154% of the month's rain in one day.

This is the volatile part. April rainfall has ranged from 7 mm to 203 mm across the twenty years measured — a 196 mm spread around an average of 48 mm. The average is real but almost no individual April looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 11.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, high enough to notice on the warm days without dominating them.

How April sits in the year

Temperatures hold steady either side: 30.8 °C in March, 30 here, 28.1 in May. Nothing about the timing within the month matters much. Rain has already shifted: 7 days fewer than March had.

Daylight in April

11.7 hours of daylight, losing 0.5 hours across the month. That is between Townsville's extremes of 13.3 and 11 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 27.5 °C in April — warm enough that the water offers no relief from the heat. The sea peaks at 29 °C in February and bottoms out at 24 °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 Townsville versus nearby

If Townsville is one option among several, the nearby comparison is worth making. Airlie Beach is close enough to be a coin toss — 2.5 °C cooler, 3 days more rain. Cairns is the weaker option in April — within a degree on temperature, 11 days more rain.

So: April is a compromise. August is 22 points better and is what Townsville is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
