Cozumel is on Mexican Southeastern Time (Zona Sureste)

On devices, select "UTC-5", "Chetumal" or "Bogota" as the local time zone

  • The state of Quintana Roo observes GMT -5 year-round
    • Officially this is Mexico Zona Sureste
  • This means no Daylight Saving Time (DST) changes are observed
  • It's the same as Eastern Standard Time (EST) or Central Daylight Time (CDT) year-round
    • Avoid using US time zones such as EST or CDT because US times zones follow DST
  • Selecting "Cancun" on a device runs some risk of setting your time wrong, since many systems have not updated to the new time zone parameters
  • Up-to-date Apple devices do set the time correctly using "Cancun"
  • "Chetumal" is the capitol of Quintana Roo and systems that include it (Windows 10) should set the time correctly
  • "Bogota" works correctly as it's also GMT -5 and does not observe DST

Sunrise and sunset are fairly consistent year-round

  • Day length varies by less than 2 ½ hours over the course of the year
  • Sunset in the summer is earlier than northerners expect, 7:32 PM at the latest (end June to early July)
  • Sunset in the winter is later than northerners expect, never before 6:05 PM (late November)
  • Sunrise is from to 6:06 AM to 7:26 AM
