Weather in Mazatlan or Tepic?

Question

I will be vacationing in either of these two cities from mid-December through mid-January. What will the weather be like or what types of clothing should I be sure not to forget?

Answer 1

Tepic may be a bit cooler as it is higher, but Mazatlan should be mid 70's to low 80's day time, and low 70's to mid 60's at night.

Answer 2

Mazatlan will be HOT. Tepic can be a little cooler because its higher from sea level but I will not be cold.  Mid december, bring a sweater.
