Dallas Weather in December is a topic that deserves attention, as the city experiences a unique blend of winter weather and festive atmosphere. With average temperatures ranging from 40°F to 60°F (4°C to 15°C), December is a great time to explore the city’s outdoor events and festivals.
From the State Fair of Texas to the Dallas Arboretum and Botanical Garden’s holiday lights display, there’s no shortage of things to do in Dallas during December. However, it’s essential to be prepared for the unpredictable weather, including freezing temperatures, snowfall, and potential flooding.
Dallas Weather Patterns in December
Dallas, Texas, experiences a semi-arid climate, with December marking the beginning of winter. The city’s temperature drops significantly, and precipitation levels increase, but snowfall remains a rare occurrence. In this section, we will delve into the prevailing wind directions, temperature fluctuations, and precipitation patterns that characterize Dallas in December.
As the winter months set in, the average temperature in Dallas drops to around 46°F (8°C) during the day and 30°F (-1°C) at night. The city’s proximity to the Gulf of Mexico influences its temperature, with warmer air masses from the Gulf contributing to moderate temperatures. However, cold fronts from Canada can bring temperatures down, and wind chill can make it feel even colder.
Prevailing Wind Directions and Temperature Fluctuations
Wind plays a significant role in shaping Dallas’s weather patterns, particularly in December. The prevailing southwesterly winds bring warmer air from the Gulf of Mexico, while northeasterly winds bring colder air from Canada. These wind directions contribute to temperature fluctuations, which can occur rapidly. A southwesterly wind can bring temperatures up by 10-15°F (5-8°C) within a short period, while a northeasterly wind can drop temperatures by 10-15°F (5-8°C) just as quickly.
When southwesterly winds dominate, temperatures in Dallas typically range from 50°F (10°C) to 60°F (15°C). However, when northeasterly winds prevail, temperatures can drop to as low as 20°F (-7°C) or lower, especially when cold fronts from Canada move into the region. This temperature fluctuation makes December a challenging month for Dallas residents to adjust to the changing weather conditions.
Humidity and Atmospheric Pressure
December is also a month of increasing humidity in Dallas, with an average relative humidity of around 60%. This higher humidity contributes to the feeling of cooler temperatures, even when the actual temperature is not that cold. Additionally, atmospheric pressure plays a significant role in shaping the weather patterns in Dallas. A low-pressure system can bring warm, moist air from the Gulf, leading to increased precipitation and cloud cover. Conversely, a high-pressure system can bring cold, dry air from Canada, leading to clear skies and cooler temperatures.
Snowfall Events and Freezing Temperatures
While snowfall is rare in Dallas, December is the month when snow events become more likely. On average, Dallas experiences around 2-3 inches (5-7.6 cm) of snowfall during the entire winter season, with the majority of it occurring in December and January. However, the frequency and intensity of snowfall events can vary greatly from year to year.
Freezing temperatures are also common in December, with an average of 7-10 days when the temperature drops below 32°F (0°C). These cold snaps can bring temperatures down to as low as 20°F (-7°C) or lower, making it essential for Dallas residents to take precautions against the cold.
Impact of El Nino and La Nina on Dallas Weather
As the weather in Dallas changes throughout the year, the influence of El Nino and La Nina events cannot be overlooked. These natural climate patterns have a profound impact on the city’s weather, and it’s essential to understand how they affect Dallas weather in December. In this section, we will explore the specific weather patterns and temperature fluctuations that occur in Dallas during El Nino and La Nina events, as well as how precipitation patterns change during these events.
Weather Patterns and Temperature Fluctuations
During an El Nino event, Dallas typically experiences above-average temperatures in December, with the average high temperature reaching up to 58°F (14°C). This is due to the warming of the Pacific Ocean waters, which in turn warms the atmospheric circulation patterns, leading to increased warmth in the region. On the other hand, La Nina events tend to bring cooler temperatures, with the average high temperature dipping to around 48°F (9°C).
- El Nino: During an El Nino event, Dallas can expect to experience warmer temperatures, with an increased risk of heatwaves. This is particularly notable in December, when the average high temperature is already warmer than usual.
- La Nina: La Nina events, on the other hand, bring cooler temperatures and an increased risk of frost. This can lead to damage to crops and plants that are not winter-hardy.
It’s essential to note that while these trends are general patterns, the specific weather conditions in Dallas can vary greatly from year to year.
Precipitation Patterns and Flooding, Dallas weather in december
Both El Nino and La Nina events have a significant impact on precipitation patterns in Dallas. During an El Nino event, the city can expect to experience above-average rainfall, with an increased risk of flooding. This is particularly notable in December, when heavy rainfall can lead to significant disruptions.
“Heavy rainfall can lead to flash flooding, especially in areas with poor drainage or urban runoff,” says the National Weather Service.
- El Nino: During an El Nino event, Dallas can expect to receive up to 2.5 inches (6.4 cm) more precipitation than usual, with a higher likelihood of heavy rainfall events.
- La Nina: La Nina events, on the other hand, bring drier conditions, with a lower risk of heavy rainfall and flooding.
It’s essential to note that while these trends are general patterns, the specific precipitation conditions in Dallas can vary greatly from year to year.
Recent Years with Significant Effects
Both El Nino and La Nina events have had significant effects on Dallas weather in recent years. For example, during the 2015-2016 El Nino event, Dallas experienced an extremely wet December, with over 4 inches (10 cm) of rainfall, leading to significant flooding.
| Event | Average High Temperature (°F) | Precipitation (inches) |
|---|---|---|
| 2015-2016 El Nino | 63.1°F (17°C) | 4.5 inches (11.4 cm) |
| 2018-2019 La Nina | 47.9°F (8.8°C) | 1.5 inches (3.8 cm) |
These events highlight the importance of understanding how El Nino and La Nina events affect Dallas weather in December.

With advancements in technology, weather forecasting has become more accurate and reliable. Let’s examine how weather forecasting technology affects the accuracy of December weather predictions in Dallas.
Weather forecasting technology, such as satellite imaging and radar, has significantly enhanced the accuracy of weather predictions. Satellite imaging allows meteorologists to track cloud patterns, precipitation, and other weather-related phenomena from space. Radar technology, on the other hand, provides detailed information about precipitation and other weather conditions. These technologies work together to provide comprehensive weather forecasts that are more accurate than ever before.
