Warm nights and a dry September
Summer nights stay warm: January and February both average 22.0°C overnight, and from December to March the days are warm too. July is the coolest month, its days still averaging 21.9°C and its nights cooling to 10.3°C. From September the warmth returns month by month, and by November the days are nearly as warm as summer's.
The rain, 1,049 mm in an average year, has its heaviest month in February at 161 mm, with March the next wettest. The driest months run from June to September, with July and September level at the bottom, so the dry reaches into early spring. October then brings a sharp lift in rain before November eases and December climbs again.
An October wetter than November
Autumn carries the summer wet onward, though not smoothly: April dips between a wet March and May's 101 mm. Spring begins in the driest month of the year and keeps its rain modest, with October wetter than November, which dips before December's rain. Both seasons keep warm days at their summer ends, March averaging 29.1°C and November 28.2°C.

Ticks can be found in any month. The Australian Government’s health advice puts the usual tick season at July to December, and says it differs from place to place.
