Understanding these climatic patterns and risks, particularly regarding heat, tornadoes, and flooding, is crucial for residents and urban planning in this rapidly growing metropolitan area.

Key Climate & Hazard Factors

Extreme Summers Dallas summers are known for intense heat, often influenced by heat domes, with August typically being the hottest month. Temperatures frequently exceed 90°F (32°C).
Tornado Alley Situated in the southern part of Tornado Alley, Dallas faces a significant risk of tornadoes, especially during the spring months (March-May), driven by supercell thunderstorms.
Flash Floods Heavy, sudden downpours, especially in an urbanized environment with extensive impervious surfaces, make flash flooding a common and dangerous hazard, particularly around the Trinity River basin.
Humid Subtropical Dallas falls under a humid subtropical climate (Köppen: Cfa), characterized by hot, humid summers and generally mild to cool winters.
