Like many places around the world, it is very hot in Memphis currently. When I checked to see how hot it was, I was in for a surprise.
I’m a long-time CARROT Weather user, and love the app for its customization options and powerful UI. One of those features is the ability to change the source for the weather data shown in the app.
I’ve used Foreca for years, as according to Forecast Advisor, it’s among the most accurate sources for where I live.
However, I have noticed that Foreca tends to be a little aggressive when it comes to the heat index, often being much higher than other sources. Today, that was very apparent:
Foreca has the heat index at a whopping 138 °F (58.9 °C) while Apple Weather and AccuWeather are far less murdery at 108 °F (42.2 °C) and 115 °F (46.1 °C), respectively. AerisWeather, the next-most accurate source for my area, has the index at 110 °F (43.3 °C).
No weather service has perfect data. Apple Weather seems to inflate precipitation chances for me, while AccuWeather and others have been caught selling user data without making the proper disclosures to users. For now, I’ve swapped CARROT over to using AerisWeather’s data and seeing how things go.
