The weather in Dallas is influenced by its inland position, away from the moderating effects of large bodies of water. This results in a humid subtropical climate, characterised by hot summers and mild winters, with temperatures ranging from 37°F to 96°F (3°C) to (36°C) throughout the year. It's rare for temperatures to drop below 24°F (-4°C) or rise above 102°F (39°C).

The warmest months in Dallas are typically between June and September, during which residents and visitors can expect temperatures to hover between 73°F and 96°F (23°C) to (36°C). Rainfall is sporadic during this period, but when it does occur, it can be intense due to the city's susceptibility to thunderstorms. Winter, spanning from December to February, is relatively mild, with temperatures ranging from 37°F to 61°F (3°C) to (16°C). This season witnesses more consistent rainfall, and on rare occasions, the city might even see a dusting of snow.

Located in the Southern Plains of the United States, Dallas's climate is unique in its vulnerability to extreme weather events, including tornadoes, especially in spring and fall. The city's position in Tornado Alley means that it's not uncommon for severe weather warnings to be issued during these transitional seasons.
