Weather in Katoomba in October

Prime time. If you get to pick your dates, October is the one. Highs average 19.6 °C, lows 6.7 °C, and rain falls on 9 days — nothing in the month is working against you.

October is the highest-scoring month of the twelve. The nearest rival is April, and the month at the other end of the year is June.

Rain on 9 days, 2 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

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average October reaches 30 °C. Across the twenty years measured, the hottest October day reached 29.3 °C and the coldest night fell to -2 °C, and the wettest single day dropped 42 mm — roughly 75% of the month's rain in one day.

October is moderately variable: 5 mm in the driest year against 111 mm in the wettest, around an average of 56 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 1.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 63%.

How October sits in the year

The month is on the way up: 3.7 °C warmer than September, and November adds another 3.3 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in October

12.9 hours of daylight, gaining 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

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, May is the trade worth considering — 12 points weaker on weather, and materially quieter.

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

October 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 — within a degree on temperature, 1 day less rain. Sydney is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: October is the answer for Katoomba. If it is booked out or priced out, April is the next best thing at 1 points behind, and June is the month to keep off the shortlist.
