One clean arc of rain
The station's rain follows a single arc. From December, the driest month at 10 mm, January to March stay dry, then each month from April is wetter than the last until July, the wettest at 140 mm, and from there each month is drier again, all the way back to December. There is no second wet spell. Across an average 699 mm a year, the heavy months run from May to September.
January and February share the warmest average daily maximum, 32.3°C, and those same months are among the driest of the year. July, the wettest month, is also the coolest, with average days of 18.5°C and nights of 8.2°C. At the station, warm and dry arrive together, and so do cool and wet.
A warm March, a wet September
Autumn is the warmer season at the station, with an average daily maximum of 26.3°C to spring's 23.8°C, and March's days are warmer than those of any spring month. Spring is the slightly wetter season. Its wettest month is September, at 79 mm, while October and November are already among the drier months of the year.

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.
Australian Centre for Disease ControlWho licenses pest work in Western Australia
In Western Australia, a commercial pest management business must be registered with the state’s Department of Health before it provides services. WA Department of Health
Treatments are done by pest management technicians or provisional technicians, and both must work for a registered business, their own or an employer’s. WA Department of Health
A provisional technician is still training for the full licence and is not allowed to work without supervision. HealthyWA (WA Department of Health)
After up to 30 working days of close, in-person supervision, an adult provisional technician may work under a licensed technician’s direction. HealthyWA (WA Department of Health)
Doing pest management work for others without a licence, or running a pest management business that is not registered, is an offence. WA Department of Health
Technicians licensed in New South Wales, Victoria, South Australia, Tasmania, the ACT or the Northern Territory, though not Queensland, may be eligible to work in Western Australia for a time under automatic mutual recognition, once they have notified the department and received its notice of registration. WA Department of Health
A technician’s licence card lists endorsements, which show the pesticide treatments the holder is qualified to carry out. HealthyWA (WA Department of Health)
HealthyWA suggests checking for the right endorsement before any work begins. HealthyWA (WA Department of Health)
