The Nuevo Laredo municipality is the northernmost in Tamaulipas, lying at the extreme northwestern tip of its narrow strip of land along the Río Grande.

Nuevo Laredo is located in the Northern tip of Tamaulipas on the west end of the Rio Grande Plains.

The area consists of a few hills and flat land covered with grass, oak, cacti, and mesquite.

Nuevo Laredo is cold for Tamaulipas standards during winter, the average daytime highs are around 66 °F (19 C) and overnight lows around 43 °F (6 C); although it is rare for snow to fall in Nuevo Laredo, there was actually snow on the ground for a few hours on the morning of Christmas Day 2004.

The Síndicos supervise the municipal budget and expenditures, and the Regidores are elected by the party.
