Weather in Mexico in January

January in Mexico is cool outdoor weather: usable if you dress for it, not a beach brief.

A country pin in January is a warning: one region of Mexico will not match another. Use a city page if you already know where you are going. January is the cold side of the year in Mexico. Pack for that, not for a leftover summer photo.

What to expect

Daytime

Cool days in Mexico: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.

Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.

Rain

Rain is not the story in Mexico in January. Pack for sun. A shower would be news, not a plan.

Do not build the trip around weather windows. Build it around shade if it is hot, and around getting outside if it is not.

Evening

Evenings are cooler. A layer helps after sunset.

What to pack

  • Sun protection

  • A layer for cooler evenings
