The weather in Dallas is influenced by its inland position, set back 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. Temperatures occasionally drop below 24°F (-4°C) during winter cold snaps, and summer regularly brings stretches above 102°F (39°C).
The warmest months in Dallas are from June through September, and August claims the title of hottest. During this season, residents and visitors can expect temperatures 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 brings more consistent rainfall. Snow is uncommon – a light dusting some years, nothing in others – but ice storms pose the greater winter threat, occasionally shutting down the city for days.
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.
