Houston's weather is anything but predictable. From sweltering summers to unexpected cold snaps, the city's climate keeps residents on their toes. Let's dive into some fascinating facts about Houston's weather.

  1. Houston's Humidity: Houston is known for its high humidity levels. The Gulf of Mexico plays a significant role in this, as moist air from the gulf often makes its way into the city, creating a muggy atmosphere.

  2. Summer Heat: Summers in Houston are notoriously hot. Temperatures often soar above 90°F (32°C), with heat indices making it feel even hotter. Air conditioning is not just a luxury; it's a necessity.

  3. Hurricane Season: Houston is no stranger to hurricanes. The city is vulnerable to these powerful storms, especially from June to November. Hurricane Harvey in 2017 is a stark reminder of the devastation these storms can bring.

Rain, Rain, and More Rain

Houston's weather isn't just about heat and humidity. The city also experiences significant rainfall, contributing to its lush green landscapes.

  1. Annual Rainfall: Houston receives an average of 49.8 inches of rain annually. This is higher than the national average, making it one of the wettest major cities in the United States.

  2. Flash Flooding: Due to its flat terrain and heavy rainfall, Houston is prone to flash flooding. The city's drainage systems can become overwhelmed, leading to rapid water accumulation on streets and in neighborhoods.

  3. Cold Snaps: Occasionally, Houston experiences sudden cold snaps. These can bring freezing temperatures and icy conditions, which can be challenging for a city unaccustomed to such weather.
