For the past three years, an outdoor skating rink has been built each winter in Mexico City's Zocalo, or Main Square. Average temperatures in the city range from 7-23 celsius this time of year. 

This novelty is ridiculously popular with locals, and a queue can be found from opening to closing every day. (10am to 10pm)  Due to popularity, skaters are given a 45 minute time limit.

The ice surface is known as one of the largest in the world, and is most likely the largest ice surface close to the equator. 

Skating here is free of charge, a project sponsored by the local government to make Mexico City "more fun." Mexico is of course not known for its winter sport activities. In fact, Mexico is North American's most popular winter vacation spot, a place to get away from the cold winters in the North. 

The Zocalo rink is open for one month per year – from December 7 to January 7.  It can accommodate more than 1,200 skaters at one time.
