Where does the data come from? Weather Channel says 7/5 and 27/19 for the next two days, yet my watch says-7/-28 and 4/-25. Not even close.
We could write volumes about the reliability of weather forecasting in general.
However, with regard to the weather data provided through the API that is used in Facer the provider is OpenWeathermap.org
You can go to their website to view the forecast that applies to your location at https://openweathermap.org/
Their data is not always the same as what you’ll find with Accuweather (The Weather Channel), NOAA, Weather Bug, or other services but it’s pretty close.
I have developed some watch faces myself with a new 5-day forecast model about to be released. I spent a lot of time reading the API specs and find that the Day1 Forecast is really tricky. First of all, some facer developers use Day1 Forecast as “tomorrow’s” forecast. That is not correct. Day 1 Forecast is “Today.” To make matters more complicated the OpenWeatherMap.org data for “today” will changed based upon the time of day to show the HIGH TEMP from the current time forward. For example, at 8AM the HIGH may be 50F and the actual temp may reach 50F around noon. By 3pm the current temp begins to fall as expected. When the current temp drops to 40F (as an example) the Day 1 Forecast HIGH will also drop to 40’ish instead of the original 50. Sheesh! It’s complicated.
The Day 2 Forecast (tomorrow) and forward is more consistent with what you’d see with other weather services.
Bottom line… Facer is at the mercy of OpenWeatherMap.org for the data and not all face developers see the Day1-5 schedule the same and the resulting faces may be inaccurate by day but not by value.
Probably TMI but I hope that this helps.
Keep an eye out for my RichM DigInfo Forecast face. It’s free and I think you’ll find that the forecast implementation is as reliable as the service permits.
