Weather in Broome in October

The month to avoid. October is the month most people should skip in Broome. Daytime highs average 38.8 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.

October ranks 10 of 12 — near the bottom of Broome's year. June is the month that works, and the swing between the two is 56 points, which is a different holiday rather than a slightly better one.

Rain falls on only 2 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.

What the averages hide

Averages flatten a month, and this one hides a few things: 28 days of the month clear 35 °C — that is not a heatwave, it is the month. Across the twenty years measured, the hottest October day reached 45.1 °C and the coldest night fell to 16.7 °C.

October is dependably dry, and that reliability is the point: across the twenty years measured, the wettest October on record still only managed 32 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Octobers brought 9 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 11.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 51%.

How October sits in the year

Temperatures hold steady either side: 36.1 °C in September, 38.8 here, 39.5 in November. Nothing about the timing within the month matters much.

Daylight in October

12.5 hours of daylight, gaining 0.5 hours across the month. That is between Broome's extremes of 13.2 and 11.1 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 26.8 °C in October — warm enough to stay in as long as you like. The sea peaks at 30.2 °C in March and bottoms out at 24.7 °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

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

October in Broome versus nearby

If Broome is one option among several, the nearby comparison is worth making. Labuan Bajo is a better bet in October — 6.2 °C cooler, 13 days more rain. Darwin is a better bet in October — 5.7 °C cooler, 11 days more rain.

So: October is a compromise. June is 53 points better and is what Broome is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
