Winnipeg, Manitoba's vibrant capital located at the confluence of the Red and Assiniboia rivers, experiences a continental climate with harsh winters and warm summers that create distinct pollen seasons. This prairie city faces significant allergy challenges, particularly from ragweed in late summer and fall, with pollen seasons extending due to climate change. This comprehensive guide covers Winnipeg's pollen types, seasonal patterns, recent trends, and practical strategies for managing allergies throughout the year.
Pollen count measures the concentration of pollen grains per cubic meter of air, with levels categorized as low (1-20 grains/m³), moderate (21-80 grains/m³), or high (81-200 grains/m³). When pollen counts are elevated, allergy sufferers may experience sneezing, itchy eyes, nasal congestion, coughing, and difficulty breathing. Monitoring daily pollen levels helps residents plan outdoor activities and manage symptoms effectively.
Winnipeg's pollen landscape is dominated by three major categories: tree pollen in spring, grass pollen in summer, and weed pollen in late summer and fall. Ragweed stands out as the most significant allergen, with climate change dramatically impacting its season length. Between 1995 and 2015, Winnipeg's ragweed season extended by 25 days, reflecting broader trends documented in a 2019 Lancet Planetary Health study showing over 70% of studied cities experienced increases in annual pollen rates.
Winnipeg's prairie location and prevailing winds expose the city to pollen from vast open areas, intensifying ragweed exposure. University of Manitoba researchers warn that warmer winters will likely continue increasing both the incidence and prevalence of allergic respiratory conditions, making pollen monitoring increasingly important for public health.
Winnipeg's pollen calendar follows distinct seasonal patterns influenced by the region's continental climate.

Pollen season in Winnipeg typically runs from mid-March through October, with distinct phases throughout the year. Tree pollen dominates from March to June (birch, oak, ash, and elm being the main culprits), grass pollen peaks in July, and weed pollen, especially ragweed, takes over from late July through October. Climate change has extended the ragweed season by 25 days in recent decades, meaning allergy sufferers now face a longer overall pollen season.
The most common pollen allergens in Winnipeg are ragweed, birch, oak, ash, and various grass species. Ragweed is the dominant allergen from August through mid-September and remains active until the first hard frost in mid-October. Birch and oak are highly allergenic tree pollens that peak from late April through late May, though birch season timing can vary by up to a month year-to-year due to Winnipeg's extreme weather fluctuations. Grass pollen reaches its highest levels specifically in July, with moderate to high counts from late May through the end of July.
Avoid outdoor activities between 5 a.m. and 10 a.m., when pollen counts are highest as plants actively release pollen during these early morning hours. Plan outdoor exercise or gardening for late afternoon or evening instead, and use the Pollen Count & Alerts App to check daily forecasts before heading out. On high pollen days, keep windows closed during morning hours and shower after being outdoors to remove pollen from your hair and skin.
Living with pollen allergies in Winnipeg presents unique challenges, from the highly variable tree pollen seasons to the increasingly prolonged ragweed season driven by climate change.
