reposting this in case it got missed the first time around here https://developer.apple.com/forums/thread/775900 We had a question that came up when we comparing data from WeatherKit to other sources - WeatherKit visibility was well beyond the boundaries we had historically, even from Darksky. That raises two questions: is visibility actually in meters like the docs say? is this visibility at ground level, 500ft, or some other height? We were seeing visibility numbers of up to 40 miles (after converting the number the API sent to miles), where all of our other sources are usually within 10 miles

We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days. Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things. Here are some example API calls that are giving us a 404 error now https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US Does anyone have any insights or information on this? Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.

I use WeatherKit with Swift to get multiple cities weather by longitude and latitude. But I use this API in WeatherService for daily forecast: final public func weather<T>(for location: CLLocation, including dataSet: WeatherQuery<T>) async throws -> T And I found there is something wired: The date of WeatherKit::DayWeather is based on my device's timezone settings. Tokyo's Day Weather is start at UTC+8, New York' Day Weather is start UTC+8. Is there any way to set timezone correctly?

Hi, My app is going to consist of 2-3 pages of weather data. Do I have to add the Apple Weather logo to each page, or just the main one? Thanks, Dan Uff

Is there a list of countries that are currently supported by WeatherKit's WeatherAlerts?

Hello, We’re using the Apple WeatherKit API in our application and would like to better understand how the conditionCode field is determined in the hourly data. In particular, we have encountered cases where both rain and strong winds occurred within the same hour, but the conditionCode returned was related to wind (e.g. windy), even though rain was present and more relevant to our use case. Could you please clarify: What is the logic or prioritization used by WeatherKit when selecting the conditionCode for an hourly period that includes multiple weather events? Is rain ever prioritized over wind in this field? If so, under what conditions? Since precipitation has more impact for our analyses and decision-making than wind, understanding how this field is computed is important for us. Thank you in advance for your help. Best regards,

I found that only ConditionCode in the current Weather is a field related to weather description, but it is just an enumeration of weather predictions. I want to present different weather descriptions to users in different languages.What should I display to the user based on?

In the availability and pricing section, we have reviewed the plans and we will be upgrading to 50 or 100 million calls/month but before we do, we have a couple questions. Does the API have rate limit or throttling? Do you have additional weather forecast endpoints like hail, radar, or pollen forecast? I see in this thread https://developer.apple.com/forums/thread/795642 that air quality is not available Thanks

Does WeatherKit Rest api have the following forecast endpoints? Pollen and Flu Air quality Radar forecast served through a REST API? Hail Solar energy Frost Potential Index

Weatherkit stopped again providing next hour rain data for United kingdom and ireland

Hello Apple Developer Support Team, I am the Account Holder of my Apple Developer Program team (Team ID: T2BKUF6E93). My iOS app is using Swift WeatherKit (WeatherService) on device. Although my environment is completely configured, the system WeatherDaemon consistently fails to generate the WeatherKit JWT token. My environment: Team type: Apple Developer Program (paid) Team ID: T2BKUF6E93 Account role: Account Holder Xcode: latest version Device: iPhone (real device) Provisioning Profile: iOS Team Provisioning Profile (auto-managed) Entitlement: com.apple.developer.weatherkit included WeatherKit Key: created successfully (.p8 downloaded) Bundle ID: correct and WeatherKit capability enabled App reinstalled after each configuration change Device rebooted Even after enabling WeatherKit capability and generating a WeatherKit Key, the system still fails to generate JWT: Failed to generate jwt token for: com.apple.weatherkit.authservice Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" The error persists across: multiple device restarts full clean/rebuild in Xcode deleting and reinstalling the app pulling the latest provisioning profiles waiting more than several hours for backend propagation What I suspect My WeatherKit entitlement and/or WeatherKit Key may not be fully propagated to the provisioning server or WeatherDaemon backend, even though everything appears correctly configured on the Developer Center. I kindly request the support team to: Verify whether the WeatherKit Entitlement is correctly attached to my app ID and provisioning profile. Verify whether my WeatherKit Key is properly registered and propagated for my team. Check if there are any backend propagation delays or stuck states for my Team ID (T2BKUF6E93). Confirm whether WeatherDaemon has permission to generate JWT for my app. Thank you Please let me know if any logs, screenshots, or provisioning profile identifiers are needed. Thank you for your help! Best regards, Jiangyang

I have a watch only app that display an open/close park status and the current temperature with a current condition icon. That's it. On second submission the watch app was rejected due to no WeatherKit attribution. I have a lack of clarity of what's needed. With my single view that display my content I don't want WeatherKit attribution to overwhelm what's being presented to the user. I've tried looking for watch apps in the store that provide attribution and I'm not finding any. Looking for advice on how to meet this requirement without attribution overpowering my content.

Hey all, Running into an issue with a WeatherKit. Whenever I make a WeatherKit API call, I get this error: Details: { domain: WeatherDaemon.WDSClientErrors, localizedDescription: invalidAuthorization: 401, underlyingError: Unknown, code: 3 } This only happens when calling via the Swift package: swift WeatherService.shared.weather(for: location).currentWeather When I was calling the WeatherKit REST API directly from Dart, everything worked fine. So far I’ve: Enabled WeatherKit in the Apple Developer account Added the WeatherKit capability to the app Refreshed provisioning profiles Installed the app fresh on device/simulator Has anyone seen this specific invalidAuthorization: 401 from WeatherDaemon.WDSClientErrors when using WeatherService in Swift, and know what might be missing or misconfigured?

I am using the WeatherKit REST API with hourlyStart/hourlyEnd parameters to request up to 240 hours of forecast data. However, when requesting later in the day, the API returns fewer than 240 hourly forecasts — e.g., 239 at 08:00, 238 at 09:00, etc. and goes up to 224 for 23:00 It appears the returned list is contiguous but truncated at the end compared to the full 240-hour window. I have also tried getting the data after sometime, like 09:00 data at 09:45 but still was missing the same data at the end. Is this expected WeatherKit behavior or a bug? If it’s expected, is there documentation explaining how the “forecast horizon” is determined and when it is updated? Thank you.

Hey Im currently trying to use the weatherkit API and Im seeing the following returned: {"reason": "OVER_QUOTA"} Im using the correct service, key and bundle ID. Ive generated a private key too.

We are operating an application that uses WeatherKit. Despite revoking a specific WeatherKit key on the Apple Developer website, the number of API calls associated with that key continues to increase. We are looking for a way to completely disable this particular key. Any advice or suggestions would be greatly appreciated.

Starting March 24, the API is incorrectly returning 302 Moved Temporarily" redirecting the API to Location: https://developer.apple.com/weatherkit/ This is incorrect, it should be giving an API JSON response as specified by: https://developer.apple.com/documentation/weatherkitrestapi/get-api-v1-weather-language-latitude-longitude Is this happening for anyone else?

where can i find the account quota usage for WeatherAPI?

I pull an hourly UV index forecast in my app via WeatherKit, but I’ve noticed it flips back and forth between two "stable" forecasts throughout the day, as if the data source is switching between providers, as a result giving a sense of instability in the presented forecast. Is there any way to lock or specify a single forecast source for greater consistency? I have a feature that notifies users when the UV index crosses a set threshold, but these repeated “back-and-forth” changes trigger multiple alerts that feel spammy and unreliable. Any advice or best practices for handling this would be greatly appreciated.

In WatchOS 26 you can now configure Apple Watch Widgets that use AppIntents instead of having a preconfigured option via AppIntentRecommendation. This is demonstrated in the Weather Details Widget. In that, the Intent has been set up such that the options have icons for each parameter. How can I update my Intent code to offer this? struct DataPointsWidgetIntent: AppIntent, WidgetConfigurationIntent { static var title: LocalizedStringResource = "Data Points Widget Configuration" static var description = IntentDescription("Configure the individual data point display for Widgets.") static var isDiscoverable: Bool { return false} init() {} func perform() async throws -> some IntentResult { print("DataPointsWidgetIntent perform") return .result() } @Parameter(title: "Show Individual Data Points", default: true) var showDataPoints: Bool? @Parameter(title: "Trend Timescale", default: .week) var timescale: TimescaleTypeAppEnum? static var parameterSummary: some ParameterSummary { Summary("Test Info") { \.$showDataPoints \.$timescale } } } enum TimescaleTypeAppEnum: String, AppEnum { case week case fortnight static var typeDisplayRepresentation = TypeDisplayRepresentation(name: "Trend Timescale") static var caseDisplayRepresentations: [Self: DisplayRepresentation] = [ .week: "Past Week", .fortnight: "Past Fortnight" ] }
