Hi! My app, Temp Blanket, uses WeatherKit to provide users with historical high and low temperatures (as well as some weather condition info) for the location from which they wish to request data - they enter the location in a textfield that I then convert to Geo Coordinates before passing on to WeatherKit.
A user in Germany has informed me that her results for Dresden do not match the actual temperatures in the last few days. Actual temperates have been in the -13 to 2 C range and she is seeing a range of 4 to 21 C. In fact, she reports that she gets the same temperatures, no matter what location she tries. When I try Dresden in my app (from my office in Fort Lauderdale, FL) I get correct temperatures for Dresden.
Another data point - If I try to get temperatures for Nairobi, Kenya for the last few days, I get the correct temperatures for yesterday (High of 22C, Low of 16C) but the prior days' temps are very far off. I get temps in the range of -12 to 1 C but the actual temps were 15 to 26 C.
The temperature history data seems to work correctly in the UK, based on feedback from a user there.
So, I have to wonder and ask - does WeatherKit historical data work correctly for all locations worldwide or is it not reliable in certain locations/countries? This is critical information to have so that we do not have dissatisfied users in countries where this service is not yet working correctly. I would disable the app in those countries if this were the case but I need to know what those countries are.
Thanks in advance.
