What’s wrong with the iPhone weather forecast showing 80 degrees?

When you see the weather forecast on your iPhone showing over 80 degrees, it may not be that the temperature is actually that high, but that the default display on your phone is Fahrenheit. Apple devices typically automatically set temperature units based on the user's region, but users can adjust this manually. Here are the simple steps to set it up:

First, open your phone and find the Weather app.

Next, find the lower right corner of the weather forecast interface, where there is usually a settings icon, click to enter.

In the settings menu, you will see an option usually marked with "C/" or "°F", which is used to switch the temperature unit. Click the "C/" button and the system will switch to Fahrenheit temperature display. Thus, 80 degrees means 80°F, not 80 degrees Celsius. If you're used to Celsius, just remember to switch back.
