Climate chart - Corpus Christi (Texas)
The climate of Corpus Christi is subtropical, with very mild winters and very hot, muggy and relatively rainy summers.
The city is located on the west coast of Texas (the one where the rains are less abundant), at the mouth of the Nueces River, which widens into a bay. Between the bay and the Gulf of Mexico lies a barrier island, Mustang Island.
The winter, from December to February, is mild.
The sun shines quite often, although there are periods characterized by clouds, rain and wind.
Even in the middle of winter, there can be hot days, with highs around 25 °C (77 °F) and more, sometimes as high as 30 °C (86 °F).
However, there may also be cold periods, with highs below 10 °C (14 °F). Very rarely, as happened on Christmas 2004 and in December 2017, it can even snow. From 1981 to 2020, the record was -10.5 °C (13 °F), recorded in December 1989. In February 2021, the temperature dropped to -8 °C (17.5 °F).
The summer, from June to September, is very hot and muggy. Due to high humidity the heat is sweltering, even though the breeze blows from the sea.
The sun often shines, but the sky is not always clear, as cloud coverings can form, which can give rise to thunderstorms.
On the hottest days of the year, the temperature typically reaches 38 °C (100 °F). The record is 43 °C (109.5 °F), recorded in early September 2000.
From June to November (but with a higher probability from August to October), there is the risk of hurricanes. Being a coastal city, Corpus Christi is particularly exposed. The city was hit hard by Hurricane Celia in August 1970.
The average temperature of the coldest month (January) is of 14.4 °C (57.9 °F), that of the warmest month (August) is of 29.6 °C (85.4 °F). Here are the average temperatures.
