Weather in Townsville in July

Prime time. If you get to pick your dates, July is the one. Highs average 25.9 °C, lows 15.5 °C, and rain falls on 3 days — nothing in the month is working against you.

July ranks 2 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 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 July reaches 30 °C. Across the twenty years measured, the hottest July day reached 32.2 °C and the coldest night fell to 6.7 °C, and the wettest single day dropped 56 mm — roughly 255% of the month's rain in one day.

This is the volatile part. July rainfall has ranged from 1 mm to 104 mm across the twenty years measured — a 103 mm spread around an average of 22 mm. The average is real but almost no individual July looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 10.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 69%.

How July sits in the year

Temperatures hold steady either side: 26.2 °C in June, 25.9 here, 27.2 in August. Nothing about the timing within the month matters much.

Daylight in July

July sits at the dark end of Townsville's year — 11.1 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 24.1 °C in July — 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.

July 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 — 2.7 °C cooler, the same number of rain days. Cairns is the weaker option in July — within a degree on temperature, 7 days more rain.

So: July is effectively as good as it gets here — 1 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
