Weather in Byron Bay in June

A good month. June is a solid month to be in Byron Bay. Highs average 20.4 °C, lows 17.7 °C, and rain falls on 12 days — nothing in the month is working against you.

June ranks 7 of 12 in Byron Bay: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 12 days, 3 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 June reaches 30 °C; the day barely swings — 2.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 24.8 °C and the coldest night fell to 10.9 °C, and the wettest single day dropped 103 mm — roughly 95% of the month's rain in one day.

June is moderately variable: 16 mm in the driest year against 282 mm in the wettest, around an average of 108 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind sits around 19.2 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 72%.

How June sits in the year

Temperatures hold steady either side: 22.1 °C in May, 20.4 here, 19.6 in July. Nothing about the timing within the month matters much.

Daylight in June

June sits at the dark end of Byron Bay's year — 10.3 hours of daylight against 13.9 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 22.9 °C in June — comfortable for a proper swim. The sea peaks at 26.5 °C in February and bottoms out at 21.5 °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

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.

June in Byron Bay versus nearby

If Byron Bay is one option among several, the nearby comparison is worth making. Brisbane is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Coffs Harbour is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: June works, with August the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
