Water freezes at 32°F, which is 0°C.

So, any temperature above freezing is anything higher than 32°F (0°C), even 33°F (0.5°C) and up.

Because this question is so straightforward, here’s the ultra-short version you can remember:

  • Freezing point of water: 32°F (0°C)
  • “Above freezing”: any temperature > 32°F (> 0°C)

You might still sometimes see frost even when the reported air temperature is slightly above 32°F, because the ground or surfaces can be a bit colder than the air right above them.

TL;DR: “Above freezing” means warmer than 32°F (0°C).
