We had been using the Darksky Time Machine service to pull hourly weather data for months into the future. From a rough test on Darksky it appeared predictions were supported through 2038 with "reasonable" values.
In WeatherKit, the API documentation states “Dark Sky Time Machine functionality is now built into the hourly and daily weather requests.”. Via the API one can specify dailyStart and dailyEnd in a daily weather request. However, it seems that forecast data is only available up to 11 days in the future. If one tries to query dates any further out, the API does not error but it returns an empty response.
Is there something I'm missing, or is the new Weatherkit functionality capped at 11 days.
The WeatherKit API allows one to request historical data for any location from August 1, 2021 until the current time and hourly and daily forecasts for the next 10 days. One may request a combination of historical and forecast data, but requests are limited to a single contiguous 10 day period.
Weather forecasts more than 10 days into the future are not supported at this time.
