Local Environmental Conditions
Sandbar Lake Provincial Park sits among a blend of woodland and open water. With Sandbar Lake nearby, lakeside vegetation along its shore contributes to the local mix. The allergenic tree mix nearby includes maple. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen. Wind carries pollen over long distances, so the wider landscape also shapes what arrives here.
Maple leads the season in mid-spring, bringing the main tree pollen peak. Grasses take over in early summer and keep pollen in the air into late summer. Rain is heaviest in summer, often giving short breaks from high pollen levels. By mid-fall, as temperatures fall to around 5°C, pollen levels are low again.

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

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. |
