Presumably a continuation of the links which led to the opening sequence being set there.
In fact, it's taking place during the Day of the Dead celebrations.

"Mexico City will host the Premiere of the Americas for SPECTRE on Monday 2 November. It’s the first time that Mexico has hosted an international James Bond premiere, the date coinciding with the Day of the Dead festivities which feature in the film’s opening sequence.
Producers Michael G. Wilson and Barbara Broccoli commented, “We owe our magnificent Day of the Dead opening sequence, shot in Mexico City, to the expert craftsmanship of our wonderful British and Mexican crews. With 2015 being the Year of Culture between the UK and Mexico, it is fitting that the Premiere of the Americas will take place in Mexico City, on the actual Day of the Dead Festival.”
Following the UK release on October 26, SPECTRE will begin its rollout in North America and South America on 6 November."
