It begins with cooler weather and eventually we lose those precious last hours of sunlight - which this incredibly depressing image illustrates. Winter, unfortunately, is just around the corner. 

Metric Maps used NASA data to show just how quickly we lose sunlight in September. This data shows the average kilojoules of sunlight for each square meter of the United States.

The numbers fall very quickly during the month of September. Southern California and Texas are lucky enough to hold onto their sunlight a little bit longer whereas North Dakota and surrounding states lose it much earlier and quicker. The deep blue color that engulfs North Dakota, in itself, is depressing.

Let's try and look on the 'bright' side, roughly 277 days until the first day of summer!
