Pollen forecast for Christchurch today
Pollen levels in Christchurch today by trees, grasses and weeds, the forecast for the coming days, and when each plant’s pollen season usually starts and peaks.
In Christchurch, spring hay fever often starts with trees. Silver birch, planted along streets in towns around the city such as Rolleston, flowers from August to October and is now the main tree pollen causing allergic symptoms in New Zealand; macrocarpa, other cypresses and pines flower from July. These trees are not included in this forecast: for Christchurch the data source reports grass pollen only. Grasses follow in late spring and early summer, with a single seasonal peak here. New Zealand’s pollen records are fragmentary, so the calendar below is an estimate for a typical year.

On high-pollen 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.
