Sebring, FL Air Quality
EPA monitor data through 2025 · Updated August 13, 2026 · Methods
In 2025, Sebring, FL recorded 0 days above an Air Quality Index of 100, the level at which EPA begins warning sensitive groups, out of 365 days with monitoring data. Most of those bad days were driven by ozone and fine particles equally. Under the AQI rules that applied before 2013, the same air would have scored 0 days. Since 2002, unhealthy days are 100% lower on a consistent definition.
Unhealthy days by year, scored two ways
EPA changed what an AQI of 100 means in 2013 and again in 2015, so a count published before those changes is not comparable to one published after. Each panel below applies a single fixed rulebook to every year, so each is internally consistent. Why this matters.
