WeatherKit brings valuable weather information to your apps and services through a wide range of data that can help people stay up to date, safe, and prepared. It’s easy to use WeatherKit in your apps on Apple platforms with a Swift API, and on any other platform with a REST API.
WeatherKit is powered by the Apple Weather service, a state-of-the-art global weather forecast that provides all of the data you need to power your app with timely, hyperlocal weather information. This enables your app to offer current weather conditions and 10-day hourly forecasts for temperature, precipitation, wind, UV Index, and more. Minute-by-minute precipitation for the next hour and severe weather alerts are available for select regions.
WeatherKit includes a Swift API that leverages modern Swift syntax. And with Swift concurrency, it’s easy to request weather data with just a few lines of code. WeatherKit is also customizable, so you can request just the data you need. And because WeatherKit is built on time-tested Foundation and CoreLocation APIs, it’s simple to format measurements, convert units, and get location information.
In keeping with Apple’s commitment to privacy, WeatherKit is designed to give hyperlocal forecasts without compromising user data. Location information is used only to provide weather forecasts, is not associated with any personally identifiable information, and is never tracked between requests.
What’s newAvailable in iOS 18, iPadOS 18, macOS 15, watchOS 11, tvOS 18, and visionOS 2.
Access to WeatherKit is included in the Apple Developer Program, which also provides the tools, resources, and support you need to develop and distribute apps — including access to beta software, app services, testing tools, app analytics, and more.
WeatherKit requires iOS 16, iPadOS 16, macOS 13, tvOS 16, visionOS 1.0, or watchOS 9 or later. REST APIs can be used for websites and other platforms.
WeatherKit provides up to 500,000 API calls a month per Apple Developer Program membership. If you need additional API calls, the Account Holder of your Apple Developer Program membership can subscribe in the Account tab of the Apple Developer app. Subscription plans are priced in U.S. dollars, or in local currency where available.
The Account Holder can upgrade or downgrade a subscription at any time. If the Account Holder:
Please note that unused API calls don’t roll over to the next month.
When using WeatherKit in your apps, web apps, or websites, you’ll need to follow guidelines and requirements for attributing weather data from Apple. For details, view the attribution requirements section below.
For apps on Apple platforms, the WeatherKit framework is included in Xcode 14 or later. For other platforms and websites, use the WeatherKit REST API.
Use Certificates, Identifiers & Profiles to configure your Service ID and keys to access the Apple Weather service. Once you implement WeatherKit, you’ll be able to view your API call usage.
If your apps, web apps, or websites display any weather data from Apple (other than weather alerts or value-added services or products, as described below), you must clearly display the Apple Weather trademark (Weather), as well as the legal link to other data sources.
Value-added services or products means data, products, and/or services you develop that are derived from weather data from Apple and are transformed so that no user or other third party can discover, access, reverse engineer, or otherwise ascertain or use the original weather data from Apple. When displaying value-added services or products, you agree to attribute the source of the data to “Weather”, along with a notice that the data provided by Apple has been modified.
