Weather in Coffs Harbour in October
Australia · 20-year averages, October
A good month. October is a solid month to be in Coffs Harbour. Highs average 23.5 °C, lows 17.6 °C, and rain falls on 12 days — nothing in the month is working against you.
October ranks 5 of 12 in Coffs Harbour: 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: the day barely swings — 5.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest October day reached 32.9 °C and the coldest night fell to 10.9 °C, and the wettest single day dropped 100 mm — roughly 98% of the month's rain in one day.
October is moderately variable: 15 mm in the driest year against 300 mm in the wettest, around an average of 102 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.
Wind is light at 12.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.
How October sits in the year
Temperatures hold steady either side: 21.7 °C in September, 23.5 here, 24.9 in November. Nothing about the timing within the month matters much. Rain has already shifted: 5 days more than September had.
Daylight in October
12.8 hours of daylight, gaining 0.9 hours across the month. That is between Coffs Harbour's extremes of 14.1 and 10.2 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 21.6 °C in October — comfortable for a proper swim. 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
Shoulder. The value months — prices ease off and you get the place closer to itself. October is the value pick for Coffs Harbour: it scores within 10 points of August without carrying August's prices.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
October in Coffs Harbour versus nearby
If Coffs Harbour is one option among several, the nearby comparison is worth making. Armidale is close enough to be a coin toss — within a degree on temperature, 2 days less rain. Byron Bay is close enough to be a coin toss — within a degree on temperature, 1 day less rain.
So: October works, with August the better month by 10 points if the dates can move. If they cannot, nothing here should stop you booking.
