The average year, 1991 to 2020, at the Bureau of Meteorology's Toowoomba Airport weather station, which stands for Toowoomba on this page, from SILO's records, which SILO completes with its own estimates for any day the station did not record. The termite seasons are the ones the Australian Museum names and the tick months are the ones the Australian Government’s health advice gives (both below); neither is read from the weather.

Wet summers and a dry spell that starts early

Toowoomba's rain is a summer rain. December, January and February are the wettest stretch, February the wettest month at 104 mm. The fall-off comes suddenly in April, May brings a brief return, and then the months from June to September stay dry together. From October the rain rises again to December, and the station averages 706 mm in a year.

July's days at Toowoomba average 17.0°C and its nights 6.1°C, the coldest of the year. From June to August the nights stay cold. January is the warmest month, its days averaging 28.7°C. The days climb and fall through the year without a sudden jump, and from August they rise every month until December.

Spring rain that rises month by month

Spring is the warmer and the wetter of Toowoomba's two in-between seasons, with 170 mm of rain to autumn's 148 mm. Autumn's rain comes unevenly: a wet March, then the year's driest month in April, then a wetter May. Spring's builds steadily, from a dry September to a wet November.

Pests and weather, from public sources

Termites

New colonies begin when winged termites leave the nest in a colonising flight. The Australian Museum says these flights happen in warm, humid weather, mostly in spring and autumn.

Cockroaches

The Better Health Channel says cockroaches do best where conditions are warm, humid and unhygienic.

Mosquitoes

“Mosquitoes need water to breed, and some mosquitoes can breed in very small amounts of water.”

NSW Health

Ticks

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.
