Edmonton sits in the Aspen Parkland transition zone between the prairies and the boreal forest, exposing residents to pollen from both prairie grasses and northern forest trees. Its continental climate produces long, cold winters followed by compressed but intense pollen seasons, often triggering a dramatic spring pollen explosion. Ranked as one of the worst cities for allergies in Canada, Edmonton also faces compounding factors like wildfire smoke and high mold spore counts. This guide covers the key pollen types, seasonal patterns, and practical strategies to help you manage allergies in Edmonton.
Understanding Pollen Count in Edmonton
Pollen count measures the number of pollen grains per cubic meter of air, collected daily using rotation impaction samplers and analyzed through optical microscopy. In Edmonton, the Aerobiology Research Laboratories operate a monitoring station with over 32 years of data. When counts are high, allergy sufferers typically experience sneezing, runny nose, nasal congestion, and itchy or watery eyes.
Key Pollen Types and Trends in Edmonton
Edmonton's position between prairie grasslands and boreal forest creates exposure to a wide range of allergens. Birch pollen is the most significant tree allergen, reaching very high levels in May, while poplar and aspen also produce very high counts from late March through early June. Pine pollen has been increasing in Edmonton over recent years, and climate change is extending the overall pollen season with earlier starts and higher counts. Approximately 25% of Canadians suffer from allergic rhinitis, and Edmonton's ranking suggests local prevalence may be even higher.
- Birch Pollen: The dominant spring allergen in Edmonton, reaching very high levels from late April to mid-June with peak counts in May
- Grass Pollen: Mixed grasses including Timothy and Kentucky Bluegrass produce moderate to high counts from mid-June through early October, peaking in July
- Mugwort and Sagebrush: Moderate weed pollen levels from mid-July to late September, overlapping with wildfire smoke season to create compounded respiratory stress
- Pine and Spruce Pollen: Very high counts from early May through early August, with pine pollen increasing notably in recent years
Climate change is a key driver of worsening allergy conditions in Edmonton. Warmer winters lead to earlier pollen season starts, and extreme heat events like the 2021 Western Canada heat dome have contributed to significant pollen count increases in subsequent years. The North Saskatchewan River Valley, the longest stretch of connected urban parkland in North America, also acts as a major local pollen source with sheltered ravines where pollen can accumulate.
Seasonal Pollen Patterns in Edmonton
Edmonton's pollen season runs from March through September, with timing that can shift by up to four weeks depending on spring temperatures.
- Spring (March to May): Poplar, alder, and birch dominate, with birch reaching very high levels in May making this the peak tree pollen period
- Summer (June to July): Birch fades as pine and spruce peak in June, then grass pollen takes over in July reaching its highest levels of the year
- Late Summer (August to September): Weed pollen from mugwort, sagebrush, and sporadic ragweed combines with wildfire smoke and high mold spore counts to create a triple threat for respiratory health
- Fall and Winter (October to February): Pollen levels drop to minimal or zero, offering relief for allergy sufferers through the cold winter months

How can I protect myself from pollen in Edmonton, especially during the intense spring season?
Because Edmonton's long winters lead to a compressed and intense spring pollen explosion, monitoring daily pollen counts is essential. Use the Pollen Count & Alerts App to receive real-time alerts so you can limit outdoor activities on peak days, particularly during May when birch pollen surges. Keep windows closed on high-count days, shower after spending time outdoors, and be aware that wildfire smoke in late summer can compound pollen-related respiratory symptoms.
