Why the weather app is not accurate?

Hi Iichico32, 

Thank you for posting to the Apple Support Communities. 

Please start with these troubleshooting suggestions if an app on your iPhone is not loading as you would expect: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open. It can also be helpful to restart and update your iPhone before testing the Weather app again: 

• Restart your iPhone.
• Update your iPhone or iPad.

You can also stay informed about any app or service outage using Apple’s System Status tool. 

Please reply back here if you need more help with the Weather app.

All the best!
