Weather in Bundaberg in September
Australia · 20-year averages, September
Prime time. September is about as good as Bundaberg gets. Highs average 24.7 °C, lows 17 °C, and rain falls on 6 days — nothing in the month is working against you.
September ranks 3 of 12 in Bundaberg. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. 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 September reaches 30 °C. Across the twenty years measured, the hottest September day reached 32.8 °C and the coldest night fell to 9.4 °C, and the wettest single day dropped 45 mm — roughly 129% of the month's rain in one day.
This is the volatile part. September rainfall has ranged from 3 mm to 132 mm across the twenty years measured — a 129 mm spread around an average of 35 mm. The average is real but almost no individual September looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 11 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 69%.
How September sits in the year
The month is on the way up: 2.3 °C warmer than August, and October adds another 1.6 °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
11.9 hours of daylight, gaining 0.7 hours across the month. That is between Bundaberg's extremes of 13.7 and 10.6 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 23 °C in September — comfortable for a proper swim. The sea peaks at 27.7 °C in February and bottoms out at 22.6 °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, April 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.
September in Bundaberg versus nearby
If Bundaberg is one option among several, the nearby comparison is worth making. Hervey Bay is close enough to be a coin toss — 2.3 °C warmer, the same number of rain days. Rockhampton is close enough to be a coin toss — 3.7 °C warmer, 2 days less rain.
So: September is effectively as good as it gets here — 2 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
