Climate of Dallas

Vibrant wildflowers (such as the bluebonnet, Indian paintbrush and other flora) bloom in spring and are planted around the highways throughout Texas.

The weather in Dallas is also generally pleasant between late October and early December, and unlike springtime, major storms rarely form in the area.

In the spring, cool fronts moving south from Canada collide with warm, humid air streaming in from the Gulf Coast.

Based on 1991-2020 climate data, the average coldest temperature for an entire year is about 19.1 °F (−7.2 °C), placing Dallas in USDA zone 8b.

The construction forces of the Texas & Pacific worked feverishly to safeguard the long trestle carrying their tracks across the stream.

Much to the horror of residents, thousands of livestock drowned in the flood and some became lodged in the tops of trees—the stench of their decay hung over the city as the water subsided.

During the warm phase (El Niño), winter and spring are colder and receive more snow than usual.
