Weather in Maitland in September

Australia · 20-year averages, September

Prime time. If you get to pick your dates, September is the one. Highs average 23.4 °C, lows 10.1 °C, and rain falls on 7 days — nothing in the month is working against you.

September is the highest-scoring month of the twelve. The nearest rival is May, and the month at the other end of the year is January.

Rain on 7 days, 1 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 September day reached 36.4 °C and the coldest night fell to 3 °C, and the wettest single day dropped 37 mm — roughly 90% of the month's rain in one day.

September is moderately variable: 1 mm in the driest year against 96 mm in the wettest, around an average of 41 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 4.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 65%.

How September sits in the year

The month is on the way up: 4.2 °C warmer than August, and October adds another 3.7 °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

11.8 hours of daylight, gaining 1 hours across the month. That is between Maitland's extremes of 14.3 and 10 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 19.4 °C in September — swimmable, but it takes a moment to commit. The sea peaks at 24.5 °C in February and bottoms out at 19.3 °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, June is the trade worth considering — 13 points weaker on weather, and materially quieter.

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

September in Maitland versus nearby

If Maitland is one option among several, the nearby comparison is worth making. Central Coast 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 — 3.9 °C cooler, the same number of rain days.

So: September is the answer for Maitland. If it is booked out or priced out, May is the next best thing at 1 points behind, and January is the month to keep off the shortlist.
