The city is located in the southern tip of Texas, near the Mexican border, and 100 km (60 mi) away from the coast. The metropolitan area includes the neighboring cities of Edinburg and Mission. Across the Rio Grande River lies the Mexican city of Reynosa. We are in one of the hottest cities in the United States, one of the few where the average annual maximum temperature reaches 30 °C (86 °F).
The winter, from December to February, is mild.
The sun shines quite often, although there are periods characterized by clouds, rain and wind.
There may be hot periods even in the middle of winter, with highs around 30 °C (86 °F) and more.
However, there may also be brief cold periods, with highs below 10 °C (50 °F). Very rarely, as happened on Christmas 2004, in December 2017 and in February 2021, it can even snow. In recent decades, the record is -8 °C (17.5 °F), recorded in December 1989.
The summer, from June to September, is very hot and sunny, with some thunderstorms. There combination of humidity and temperature makes the heat sweltering.
