Weather in Katoomba in March

A good month. March is a solid month to be in Katoomba. Highs average 22.3 °C, lows 11 °C, and rain falls on 12 days — nothing in the month is working against you.

March ranks 5 of 12 in Katoomba: past the worst of the year but short of October, 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

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest March day reached 32.1 °C and the coldest night fell to 2.2 °C, and the wettest single day dropped 56 mm — roughly 66% of the month's rain in one day.

March is moderately variable: 25 mm in the driest year against 216 mm in the wettest, around an average of 85 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 1.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.

How March sits in the year

The month is on the way down: 3 °C cooler than February, with April dropping another 3.7 °C. The first week and the last are not the same trip.

Daylight in March

12.4 hours of daylight, losing 1.1 hours across the month. That is between Katoomba's extremes of 14.4 and 9.9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 26.3 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. At 991 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

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.

March in Katoomba versus nearby

If Katoomba is one option among several, the nearby comparison is worth making. Bathurst is close enough to be a coin toss — 3 °C warmer, 3 days less rain. Sydney is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: March is effectively as good as it gets here — 5 points behind October, which is inside the margin where the weather stops being the deciding factor and price starts being it.
