About Lightning in Texas

Located at approximately 30°N latitude, Texas is the second-largest US state, spanning multiple climate zones from the humid Gulf Coast to the arid west, where the dry line triggers some of the nation's most powerful supercell thunderstorms. Thunderstorm frequency varies within state boundaries, so this page does not publish an unsupported statewide annual average or national rank.

In Texas, the dry line from the west clashes with warm Gulf moisture, creating conditions for severe supercell thunderstorms. Peak thunderstorm activity occurs during April through June, when conditions align for the most frequent lightning strikes. With a population of 29.1 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting Texas.
