Weather in Bathurst in September

Prime time. September is about as good as Bathurst gets. Highs average 17.4 °C, lows 5.8 °C, and rain falls on 6 days — nothing in the month is working against you.

September ranks 4 of 12 in Bathurst: past the worst of the year but short of April, which is the month to book if the dates are open.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 17.4 °C days and 5.8 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest September day reached 30.2 °C and the coldest night fell to -1 °C, and the wettest single day dropped 30 mm — roughly 71% of the month's rain in one day.

September is moderately variable: 2 mm in the driest year against 114 mm in the wettest, around an average of 42 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 2.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 67%.

How September sits in the year

The month is on the way up: 4.1 °C warmer than August, and October adds another 4 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in September

11.8 hours of daylight, gaining 1 hours across the month. That is between Bathurst's extremes of 14.3 and 10 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 27.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

September in Bathurst versus nearby

If Bathurst is one option among several, the nearby comparison is worth making. Katoomba is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Dubbo is a better bet in September — 5 °C warmer, 1 day less rain.

So: September works, with April the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
