The rolling Middle Tennessee limestone landscape creates modest pollen gradients, while the humid subtropical climate supports an extended pollen season throughout this rapidly growing Nashville suburb.
Spring Hill's Tampa suburban setting in Florida produces an extended pollen season opening in December with oak and cedar before grass from surrounding Hernando County land peaks through February and March. Mugwort and nettle extend exposure into autumn, while the flat Gulf Coast suburban setting and the warm subtropical climate support near year-round pollen production throughout.

| 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. |
