South to North Texas: Temperatures Drop as Latitude Rises

Traveling south to north across Texas, temperatures generally decrease — especially in winter. The state's 800-mile north-south span crosses multiple climate zones.

Climate Gradient

• South Texas (Brownsville, Laredo, Corpus Christi): Subtropical — hot, humid summers; mild winters (rare freezes); 300+ freeze-free days
• Central Texas (San Antonio, Austin): Humid subtropical — hot summers; occasional winter freezes; 250+ freeze-free days
• North Texas (Dallas-Fort Worth, Wichita Falls): Humid subtropical → Continental transition — hot summers; regular winter freezes, occasional snow/ice; 200–220 freeze-free days
• Panhandle (Amarillo, Dalhart): Semi-arid Continental — hot summers; cold winters, frequent snow, blizzards possible; 180–200 freeze-free days

Drivers

• Latitude: Solar angle, day length
• Gulf of Mexico influence: Moisture & moderation fade northward
• Elevation: Panhandle >3,000 ft — enhances cooling
• Continentality: Distance from ocean = greater extremes

Summer Nuance

In July, the gradient reverses slightly — North Texas can be hotter than South Texas due to continental heating (less Gulf cloud/rain cooling). But annual mean temperature declines northward.
