The built in weather app on the iPhone can easily display hourly weather. Here’s how:

To display hourly weather, just simply tap and drag down from the second day shown (in this instance Wednesday).

1. Launch the weather app

2. Tap on the second day listed and drag down. The first day listed will expand to show hourly weather.

3. Tap and drag back up to return it to normal.

4. Alternatively, you can tap on the text in the weather app titled “hourly” under the city name.
