Calgary's pollen season runs from April through October, with three main allergen waves. Long winters keep early-year counts low, but spring melt triggers a fast tree-pollen ramp-up across Calgary, Alberta.
Right now: June brings grass pollen into peak in Calgary. This is typically the worst month for grass-allergic Canadians.
Spring
Apr – Jun
Tree pollen from birch, maple, oak, and alder. Birch is a leading trigger in central Canada.
Summer
Jun – Aug
Grass pollen peaks in June and July — timothy, ryegrass, and Kentucky bluegrass dominate.
Fall
Aug – Oct
Ragweed is the dominant fall allergen across southern Canada — pollen can travel hundreds of kilometres.
Conditions vary across Calgary — urban heat islands tend to extend pollen seasons by 1-2 weeks. PollenTracker uses live data plus the official Canadian AQHI scale so the air-quality number matches what you'd see on WeatherCAN or your local news.

CAUTION
Tree pollen is moderate, but 43 km/h wind may stir it up. Take your usual precautions if you're sensitive.
Weather: 43 km/h wind with gusts to 61 km/h is spreading pollen more aggressively.
Lower-risk hours: 14:00-16:00
