Weather in Coffs Harbour in July

Prime time. July is about as good as Coffs Harbour gets. Highs average 18.5 °C, lows 13.7 °C, and rain falls on 8 days — nothing in the month is working against you.

July ranks 3 of 12 in Coffs Harbour. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 8 days, 1 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 July reaches 30 °C; the day barely swings — 4.7 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 24.1 °C and the coldest night fell to 8.5 °C, and the wettest single day dropped 33 mm — roughly 80% of the month's rain in one day.

July is moderately variable: 2 mm in the driest year against 107 mm in the wettest, around an average of 41 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 11.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.

How July sits in the year

Temperatures hold steady either side: 19.1 °C in June, 18.5 here, 19.4 in August. Nothing about the timing within the month matters much.

Daylight in July

July sits at the dark end of Coffs Harbour's year — 10.4 hours of daylight against 14.1 at midsummer, gaining 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 20.6 °C in July — swimmable, but it takes a moment to commit. The sea peaks at 25.8 °C in February and bottoms out at 20.5 °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. If the dates are flexible, October is the trade worth considering — 10 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Coffs Harbour versus nearby

If Coffs Harbour is one option among several, the nearby comparison is worth making. Armidale is the weaker option in July — 6.3 °C cooler, 2 days less rain. Byron Bay is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: July is effectively as good as it gets here — 6 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
