Local Environmental Conditions
The area around the heart of Penticton is mostly built-up land, with some open water. Close to standing water, lakeside trees such as willow, poplar and alder contribute to what is in the air. The allergenic tree mix nearby includes maple, poplar and alder. Grasses are a major source, with mugwort and plantain adding to the weed pollen load.
Alder opens the pollen season in early spring. Maple and poplar follow in mid-spring, bringing the main tree pollen peak. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. The season closes with mugwort and plantain from midsummer into early fall. By mid-fall, as temperatures fall to around 5°C, pollen levels are low again.

When is pollen season in Penticton?
How often is the Penticton pollen forecast updated?
The Penticton pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Penticton 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 Penticton 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 Penticton, 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. |
