It's Way Too Hot on the New York City Subway

PSA for the New York City subway crowd: Overheated platforms are a health hazard, on and off of peak commuter hours. On Thursday, temperatures inside at least one of the busiest stations reached 104 degrees Fahrenheit—nearly twenty degrees warmer than the high in Central Park.

The Regional Plan Association, an urban planning think tank for the greater metropolitan area, took a thermometer around the system’s 16 busiest stations, plus a few more for good measure, and shared the data with CityLab. A platform at Union Square Station had the 104-degree reading at 1 p.m., which was the hottest they found, although Brooklyn Bridge-City Hall and Columbus Circle weren’t far off at 102 and 101 degrees, at around 10 and 11 a.m., respectively. Twelve out of the 16 busiest stops boiled at or over the 90-degree mark in the late morning and early afternoon.
