The conversion

80°C = 176°F

°F = (°C × 9/5) + 32, so (80 × 9/5) + 32 = 176.

80 °C is well outside the range outdoor air occupies on Earth, so there is no useful weather description for it — this page is arithmetic rather than a forecast.

The other direction

176 °F converts back to 80 °C, which is the same relationship read the other way. Going from Fahrenheit to Celsius, subtract 32 first and then multiply by 5/9 — doing it in the other order is the usual mistake and produces a plausible-looking wrong answer.
