Local Environmental Conditions
Columbus sits on the bluffs above the Tombigbee River, where the dominant vegetation is a mix of southern live oak with Spanish moss, loblolly pine, and riverside cypress, shaping the local pollen profile across the seasons. Seasonal timing here follows the broader regional pattern typical of this part of the country. None of this differs sharply from one year to the next barring unusual weather.
The pollen calendar in Columbus opens with oak and pine starting January before cedar takes over and peaks through February. Grass pollen rises through March and April, and pigweed and ragweed keep weed pollen elevated into October. Warm, humid Gulf Coast conditions stretch the spring pollen season longer than in most of the country.

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. |
