Get started with WeatherKit

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.

Powered by Apple Weather

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.

Easy to use

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.

Privacy first

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 new

  • Add details to the daily forecast, including snowfall total, sleet total, maximum and minimum visibility, and forecasts for daytime and overnight.
  • Add cloud cover percentage by cloud layer to the current weather forecast.
  • Provide additional context to current weather with comparisons to historical averages.
  • Help users better prepare for tomorrowʼs weather with information about significant temperature and precipitation changes.
  • Inform users about past temperature and precipitation statistics with historical averages by month and day of year.

Available in iOS 18, iPadOS 18, macOS 15, watchOS 11, tvOS 18, and visionOS 2.


Apple Developer Program membership

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 and later. REST APIs can be used for websites and other platforms.

Availability and pricing

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.

  • 500,000 calls/month: Included with membership
  • 1 million calls/month: US$49.99

The Account Holder can upgrade or downgrade a subscription at any time. If the Account Holder:

  • Upgrades a subscription, a new billing period is started and you can start using the new plan immediately. Your quota resets to 0 and the number of API calls is replaced based on the new subscription.
  • Downgrades a subscription, you can continue to use your current plan during the current billing period.

Please note that unused API calls don’t roll over to the next month.
