Weather in Byron Bay in April

A good month. April is a solid month to be in Byron Bay. Highs average 24.1 °C, lows 21.9 °C, and rain falls on 14 days — nothing in the month is working against you.

April ranks 8 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 14 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 April reaches 30 °C; the day barely swings — 2.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 28.6 °C and the coldest night fell to 15.6 °C, and the wettest single day dropped 59 mm — roughly 61% of the month's rain in one day.

April is moderately variable: 25 mm in the driest year against 229 mm in the wettest, around an average of 96 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind sits around 18.6 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 74%.

How April sits in the year

Temperatures hold steady either side: 25.6 °C in March, 24.1 here, 22.1 in May. Nothing about the timing within the month matters much. Rain has already shifted: 5 days fewer than March had.

Daylight in April

11.4 hours of daylight, losing 0.8 hours across the month. That is between Byron Bay's extremes of 13.9 and 10.3 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 25.3 °C in April — warm enough to stay in as long as you like. 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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

April 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, 2 days less rain. Coffs Harbour is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: April works, with August the better month by 15 points if the dates can move. If they cannot, nothing here should stop you booking.
