I have seen Apple engineers post numerous times on threads about this topic. Each time they state that historical data goes back to Aug 1, 2021 and that's it. It's a joke really. If you truly need historical data (and an actual reliable weather API), you should probably consider something else.

Same here. It's a shame that they took such a great product and ruined it in less than 2 years. As of today my app is not working. Same API calls in postman take over 10 seconds and some only giving errors. Shameful.

It was first noted almost 2 years ago that the Dark Sky API would stop on March 31, 2023. You will need to switch to WeatherKit to keep your weather apps working.

I started getting the same message. Renewed my bearer token with a new one and the problem is resolved. Seems strange as I created a key with an expiration date 7 years in the future. It does seem like the key expired though.
