Weather in Townsville in June
Australia · 20-year averages, June
Prime time. If you get to pick your dates, June is the one. Highs average 26.2 °C, lows 16.4 °C, and rain falls on 5 days — nothing in the month is working against you.
June ranks 3 of 12 in Townsville. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain falls on only 5 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
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest June day reached 32.2 °C and the coldest night fell to 7.6 °C.
This is the volatile part. June rainfall has ranged from 3 mm to 139 mm across the twenty years measured — a 136 mm spread around an average of 24 mm. The average is real but almost no individual June looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 10.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.
How June sits in the year
Temperatures hold steady either side: 28.1 °C in May, 26.2 here, 25.9 in July. Nothing about the timing within the month matters much.
Daylight in June
June sits at the dark end of Townsville's year — 11 hours of daylight against 13.3 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
Sea temperature
The sea sits at about 24.9 °C in June — warm enough to stay in as long as you like. 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
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.
June 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 — 2.3 °C cooler, 1 day more rain. Cairns is the weaker option in June — within a degree on temperature, 6 days more rain.
So: June is effectively as good as it gets here — 4 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
