Local Environmental Conditions
The heart of Port Coquitlam is surrounded mainly by built-up land, with a good deal of woodland. Along a stream or river nearby, trees such as willow, poplar and alder grow in the damper ground and add their own pollen. Of the allergenic trees nearby, maple matters most, while alder and poplar also contribute. Grasses and weeds such as plantain round out the local mix.
First to flower is alder, in mid-spring. Maple and poplar follow in late spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in midsummer, with temperatures around 15°C, and their pollen lingers into late summer. Plantain brings a final peak from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen.

How often is the Port Coquitlam pollen forecast updated?
The Port Coquitlam pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Port Coquitlam come from nearby or far away?
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.
Are pollen levels in Port Coquitlam based on measurements or forecasts?
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 Port Coquitlam, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
