Waiting for the L Train is a painful experience. The temperature inside the platform is often one of the highest in New York City.
This is due to 'heat sink' which is when heat from buildings and the sidewalk transfer heat outward. L-Degrees predicts the temperature daily by using the above ground temperature and data collected from countless readings looking at the difference between above ground temperature and platform temperature.
