Local Environmental Conditions
Here, nearby, the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers. As with most local readings, actual levels can vary somewhat with short-term weather swings. The general pattern described here holds fairly steady across nearby areas with similar land cover. Local wind exposure and land use can shift the exact mix slightly from block to block.
The bank's hazel and willow kick off the pollen season ahead of the rest, leading off the pollen calendar, with a peak generally falling in late winter. Through late spring, grass pollen climbs steadily toward its June peak, handing off to ragweed, which peaks from mid-August through October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

When is pollen season in Lakeshore?
How often is the Lakeshore pollen forecast updated?
The Lakeshore pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Lakeshore 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 Lakeshore 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 Lakeshore, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
