My app AirCompare is a smart home controller and makes system decisions based on local weather. Users have been seeing absurdly wrong (~10°F off) current temperatures, and of course that's a problem. I've seen similar complaints on Reddit and one poster claims that Apple switched from whatever DarkSky was using (which seemed accurate) to a predictive model from IBM. Compare iOS15 to iOS16 and you may see a large discrepancy in the Weather app. As a developer needing an accurate current temperature, I'm wondering if this is a temporary problem or whether we can expect this to continue going forward. If it's the latter, I'll need to find something more reliably accurate.

Upon requesting forecast data for more than 9 days, the API would return "400 Bad Request". Here are some values I tried (as of 2024-07-02T15:00:00Z): (dailyStart is in past) dailyStart=2024-07-01T15:00:00Z dailyEnd=2024-07-11T15:00:00Z expected= 10 days forecast actual= 10 days forecast (dailyStart is current date, forcecast > 9 days) fails dailyStart=2024-07-02T15:00:00Z dailyEnd=2024-07-12T15:00:00Z expected= 10 days forecast actual= 400 Bad Request (dailyStart is current date, forecast <= 9 days) dailyStart=2024-07-02T15:00:00Z dailyEnd=2024-07-11T15:00:00Z expected= 9 days forecast actual= 9 days forecast (no values passed) fails dailyStart= dailyEnd= expected= 10 days forecast actual= 9 days forecast The official documentation says: dailyEnd: The time to end the daily forecast. If this parameter is absent, daily forecasts run for 10 days. dailyStart: The time to start the daily forecast. If this parameter is absent, daily forecasts start on the current day. This started happening sometime last week. Would someone please tell me what changed with the API? Thank you.

Hi. The WWDC video of the v2 weatherkit api showed some examples for the REST API. However, they were very limited. The documentation for the REST API is currently for the v1 weatherkit API. When will the documentation for the v2 API be released? There are some new features of the v2 that I would really like to use, but I can't without knowing the new v2 REST API specifications. Any guidance would be much appreciated. Thanks!

Hello Apple team, I would like to request a feature to display the past temperature data (e.g., last 7 days) for each place in the Weather app(Especially past 24 hours of data for any given city ). Just like how it shows future 7-10 days of data. This would allow users to quickly view temperature trends and patterns for users like us to re-member how that day was like,etc,etc. Please consider adding a 'Past Weather' section or a graph that shows the temperature fluctuations over the past week. Thank you for considering my request!

I would like to request two enhancements to the Weather app: Add a Celsius/Fahrenheit conversion option directly on the home page, rather than requiring users to access it through the three-dot menu. Consider displaying both Celsius and Fahrenheit scales side by side, without requiring users to choose a conversion option(only if its feasible for your team). This would be particularly helpful for users who are familiar with both scales, such as Asians living in America. Thank you for considering my request!

I am using WeatherKit to display relevant weather information to the User in my App. I also thought it would be helpful to show any time-sensitive WeatherAlert. I would like to direct the User directly into the system Weather app to get more details/information. weather://open ... works... Is this a faux-pas? Is there a approved/proper way of doing this? I know WeatherAlert.detailsURL exists but I figured it may be useful for the User to see all details related to weather right from the source.

Starting in the last week or two the daily forecast returned by weatherkit rest api changed to 9 days instead of 10 days if I don't pass in the dailyStart and dailyEnd paramters. Now, if I pass in those parameters to get me anything more than 9 days then I get 400 error. 9 days or less works. Obviously something changed in the api. Apple, please fix this asap!!!

We pass a CLLocation to the new WeatherService monthlyStatistics() BUT in the returned metadata the CLLocation data does NOT match what we sent in the request. For example, send lat -27.1480114 long -109.4273371 in the monthly stat request and get back data for lat -27.148000717163086, long -109.427001953125. There’s no mention in the documentation of the returned location being “close to” the requested location. If this is working as designed how close are the results allowed to be? In my small sample they seem to be around 45-55 meters away. I’m considering less than 100 meters away to be a match, but don’t know if that’s correct.
