Weather in Broome in March

A hard month. March asks something of you. Go in knowing what. You should expect rain on 15 days of the month, which is more days wet than dry.

March ranks 7 of 12 in Broome: past the worst of the year but short of June, which is the month to book if the dates are open.

Rain on 15 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 33.8 °C days and 25.9 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 10 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest March day reached 43.4 °C and the coldest night fell to 18.8 °C, and the wettest single day dropped 67 mm — roughly 57% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 17 mm to 415 mm across the twenty years measured — a 398 mm spread around an average of 117 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 8.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.

How March sits in the year

Temperatures hold steady either side: 33.5 °C in February, 33.8 here, 34.8 in April. Nothing about the timing within the month matters much. Rain is the thing that moves: April brings 11 days less of it, so pushing the dates later buys drier weather.

Daylight in March

12.2 hours of daylight, losing 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 30.2 °C in March — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

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.

March in Broome versus nearby

If Broome is one option among several, the nearby comparison is worth making. Labuan Bajo is a better bet in March — 4.6 °C cooler, 12 days more rain. Darwin is a better bet in March — 3.7 °C cooler, 12 days more rain.

So: March is a compromise. June is 42 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.
