What to wear to Day Zero: Tulum sits at 28°C (82°F) by day and 20°C (68°F) at night in January, on forest, with a low chance of rain. That means a light base with one warm layer you can carry, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans techno, tropical and boho, so a full costume is the norm rather than the exception.
