Make sense of the weather

Learn what the numbers and the alert words mean, or make the forecast easier to read on your iPhone. These guides are available now, while Bold Weather is testing on TestFlight.

If you want to understand a forecast

Begin with how to read a weather forecast. Then read about feels like and wind chill, heat advisories, the UV index, and air quality and pollen, which the built-in Weather app shows. The radar guide explains the colors and the motion on a radar map.

If you want alerts on your phone

The weather alerts on iPhone guide explains the difference between a watch, a warning, and an advisory, and how to turn on notifications.

If you want a clearer view

Try the iPhone text-size guide, add a weather widget to your Home Screen or Lock Screen, or use the readable app checklist to compare apps on your own phone.

Every guide is general information. Weather safety guidance comes from the linked official sources, and none of it is medical advice.
