Weather is a weather forecasting mobile app developed by Apple Inc, available on iOS since the release of the iPhone and iPhone OS 1 in 2007. It allows users to see the conditions, forecast, temperature, and other related metrics of the device's current location, as well as a number of other cities. A version of Weather is also available for watchOS and Apple Watch devices, however, is limited in functionality; Weather exists only as a widget for iPadOS devices with similarly limited functionality.
Earlier versions of Weather up through the release of iOS 7 sourced the app's forecast data from Yahoo! Weather; in March 2019, Yahoo! shut down the servers distributing data for the Weather app on devices supporting iOS 7 and earlier operating systems. Since iOS 8, The Weather Channel has been used as the app's weather data source.
Locations can be added or removed by pressing the list icon in the bottom right corner of the application, which allows the user to type in the city's name, ZIP Code or postal code or airport code. For each city, the app will display the current, highest, and lowest temperatures, a 10-day forecast, UV index, time of sunrise and sunset, current wind direction and speed, rainfall measurements, current humidity, outdoor visibility range, and barometric pressure. In some locations, the app will also display an air quality report and show next-hour precipitation when raining or snowing.
iOS 14 introduced support for severe weather warnings, allowing a user to receive notifications for government-issued severe weather events such as tornadoes, flash flooding, strong winds, and snow storms. With iOS 15, a weather map can be accessed from the bottom left of the application which can display the temperature, air quality, and a multi-day precipitation forecast.
Inability to display 69°
In July 2021, some testers of the iOS 15 beta software noticed that the Weather app avoided displaying an accurate temperature when it was 69°F. Former Apple developer Joo Pavo speculated that the app uses whole numbers in Celsius for the temperature data, later converting it to Fahrenheit for the user interface and thus making it impossible for any number that was not the result of the conversion to be displayed.
