Website with platform temps for the L train

Am I the last person to know about the genius website L-Degrees.com? When it's miserably hot -- like today, for instance -- you can torture yourself even more by checking out how hot it feels on each of the L train subway platforms. So, right now, as I'm writing this post, it feels like 108F at 14th Street. You can practically feel the sweat dripping down your back just thinking about it. 

The L info is not so useful for us in the Slope. If they had this for every subway line, would it change your commute plans? When it feels like a damn sauna outside, I definitely choose the Grand Army Plaza 2/3 over the Flatbush and 7th Q, if I can make that work, depending on where I'm going.
