As we all know that we need to unlock iPhone if users want to see weather conditions, unlike Andriod, this is not default feature in iOS.

But there is a Twig tweak (thanks to Creatix Team) brings weather/temperature status on your lock screen, now supports iOS 11 Electra jailbreak.

The Twig is quite simple in weather tweak, it will make the weather icon and tempreature on the left side of the unlocking screen. The default time and date info will be moved to the right side. You could preview as below：

But to remind, this feature needs to permanently open the privacy of weather and location, or it can't read any data on your lock screen.

To set location, go to Settings-Priavcy-Location Services, abd find the Wether and set it to Forever.
