Local Environmental Conditions
Oak Hills — Located practically next door, 200 meters off, this area has woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. Ground-level conditions like local landscaping can nudge these figures slightly either way. Nearby weather stations report comparable trends across the broader stretch of the county.
By mid-spring, oak and birch in the woods take over, typically landing in April and May. Grass pollen takes over next, building to a peak around June, followed by ragweed's own peak stretch from mid-August into October. This general pattern holds fairly steady across the surrounding county from year to year.

| 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. |
