Climate chart - Laredo (Texas)
The climate of Laredo is sub-tropical, with a very mild winter and a very hot, muggy summer.
The city is located in southern Texas. Beyond the Rio Grande River is the Mexican city of Nuevo Laredo.
We are on the 27th parallel, not far from the Tropic, and indeed the hot season is very long.
The winter, from December to February, is very mild, though with sudden changes in temperature.
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).
However, there may also be short cold periods, with highs below 10 °C (50 °F).
On the coldest days of the year, the temperature typically drops just below freezing, but once every few years there can be more intense cold spells. The record is -9.5 °C (15 °F), recorded in December 1989. In December 1983 and February 2021, the temperature dropped to -8 °C (17.5).
Very rarely, as happened on Christmas 2004 and in December 2017, it can even snow.
The summer, from June to September, is very hot and quite sunny, although sometimes a thunderstorm can break out. There are long periods, sometimes whole months, with maximum temperatures around 40 °C (104 °F). It is often very hot even in May and October, and sometimes in late April. We are in the hottest part of Texas. The record is 45 °C (113 °F), recorded in June and in July 1998.
From time to time, the city can be reached by the remnants of a hurricane, coming from the Gulf of Mexico or the Pacific. In general, hurricanes weaken when they penetrate inland, however, they can still bring abundant rains. The hurricane season runs from June to November, although they are more likely from August to October, with a peak in September.
The average temperature of the coldest month (January) is of 14.2 °C (58 °F), that of the warmest month (August) is of 31.7 °C (89 °F). Here are the average temperatures.
