Southern California is experiencing uncharacteristically high humidity this summer, with dew points near 70°F in Los Angeles.

- Dew point vs. humidity: What’s the difference and why does it matter in Tennessee
The article explains that dew point and relative humidity are distinct meteorological measures. Dew point indicates the temperature at which air becomes saturated with moisture, while relative humidity shows the percentage of moisture in the air relative to temperature. In Tennessee, dew points in the 70s during summer create oppressive conditions, making dew point a more reliable indicator of comfort than fluctuating relative humidity.
