Pollen forecast for Perth today
Pollen levels in Perth today by trees, grasses and weeds, the forecast for the coming days, and when each plant’s pollen season usually starts and peaks.
In Perth, grass pollen triggers most hay fever from October to December, according to Perth Pollen, the city’s pollen monitoring and forecast service, run with Curtin University. Its outlook for 2025 expected levels to build through November. Perth Pollen launched in November 2022 as Western Australia’s first real-time pollen count, so local records are still relatively short. The seasonal calendar below is a model-based estimate for a typical year, and the exact start of the grass season depends on the weather. Check the forecast above for the levels expected over the next few days.

- Pollen levels are usually highest on warm, dry and windy days; rain washes pollen out of the air for a while.
- Keep windows closed when the level is high and air rooms after rain.
- After a long time outdoors, change clothes and wash your hair; dry laundry indoors.
- Sunglasses help keep pollen out of your eyes.
- If you have allergy symptoms, talk to a doctor — this page does not replace medical advice.
