Your weather app says 34°F. But at ground level - where your plants actually live - it's 26°F. That difference is the reason you keep losing plants to "surprise" frosts. Frost Watch uses atmospheric science to predict what's really happening at ground level. Instead of relying on a simple temperature threshold, it calculates frost risk using dew point, cloud cover, wind speed, humidity, and radiative cooling physics - the same factors professional meteorologists use.
