The honest read on Mexico in January: two climates, not one
The single biggest mistake January visitors make is treating Mexico as one climate. The Caribbean coast and the central highlands run roughly 15 degrees apart this month, and the gap bites after dark. Cancun sits around 27C by day and stays near 20C at night, so swimwear genuinely works. Mexico City, by contrast, is in its coldest month: highs near 19-21C but lows around 5-7C, with a steep daily swing on the dry, thin-air plateau. Oaxaca runs warm by day (around 26C) but drops to roughly 8C at dawn. Pack a real jacket for the interior, not just a sun hat.
On timing, two January details are worth planning around:
- Gray whale season is starting, not peaking. Bahia Magdalena tours open January 1 and Laguna San Ignacio from mid-December, but the close-contact, calf-heavy weeks run mid-January into March, so early January is the quieter, lower-yield end.
- January 6 is Dia de Reyes, when families share Rosca de Reyes; whoever finds the hidden figurine hosts tamales on Candelaria, February 2.
The honest catch: this is peak season. Expect higher coastal prices and crowded ruins around Tulum and Chichen Itza, and book lodging weeks ahead.
