🤠 Dallas Weather

Where Southern heat meets the storm belt

Dallas, in north-central Texas, has a humid subtropical climate but sits far enough inland and north to feel a continental edge the Gulf cities don't. That puts it on the southern end of the storm belt, where clashing air masses brew some of the most violent springtime weather in the country — and where summer heat and winter ice both make regular appearances.

Severe spring storms

Spring is the volatile season. Warm Gulf moisture colliding with dry air and cold fronts spawns powerful thunderstorms across the Dallas–Fort Worth Metroplex, bringing large hail, damaging winds, and tornadoes — a destructive tornado struck the city itself in October 2019. April and May are the peak of this severe-weather season.

Hot summers, icy winter snaps

Summers are long and hot, with highs frequently topping 100°F (38°C) in July and August under the strong Texas sun. Winters are mostly mild, with highs in the upper 50s°F (around 14°C), but the region's signature cold-weather hazard is ice: Arctic fronts can bring disruptive freezing rain and the occasional paralyzing deep freeze.

Dallas averages about 40 inches (1,020 mm) of rain a year, much of it in spring and autumn thunderstorms, with comparatively dry mid-summers.

On the edge of Tornado Alley

Dallas endures long, blistering summers with strings of 100°F (38°C) days and warm nights, as the flat North Texas terrain offers no relief from the sun. The dryness of the heat can be deceptive, pushing heat risk higher than the numbers suggest.

Spring is the volatile season: the Metroplex sits at the southern end of Tornado Alley, where Gulf moisture and dry-line boundaries collide to spawn supercells, giant hail, and tornadoes. Winters are mostly mild, but the occasional Arctic outbreak brings ice storms — 'Icemageddon' — that shut the sprawling, car-dependent region down.
