Vancouver pollen forecast - today, tomorrow and the week ahead

On 16 July 2026, overall pollen levels in Vancouver are moderate. Grass is the main contributor to airborne pollen, while ambrosia remain at lower levels

On 17 July 2026, pollen conditions in Vancouver will be different from today, with ambrosia at low levels and grass continuing to decline

According to the five-day outlook, grass and ambrosia pollen levels will increase later in the week.

On 16 July 2026, Grass is the dominant pollen source in Vancouver. ambrosia are also present but at lower levels. birch, cypress, oak, willow, alder, and artemisia are not currently active.

Wrapped in Pacific marine air along Burrard Inlet, Vancouver experiences an unusually long and mild pollen season, with alder and cedar releasing pollen as early as February, grasses staying active through a cool, damp summer, and mould spores often outlasting ragweed as the region's dominant late-season allergen compared with drier parts of Canada.

The Vancouver pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Vancouver, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
