On average, there are about 7 to 9 rainy days during December, with most rainfall events being light to moderate in intensity.

One of the factors affecting precipitation patterns in Austin during December is the presence of cold fronts. These weather systems can bring cooler temperatures and increased chances for rain or drizzle. However, due to the city's location in central Texas, heavy downpours and extended periods of rain are less common in December compared to other parts of the state.

It is important to consider that December marks the beginning of the winter season in Austin.

Wind and Humidity Conditions

In December, Austin experiences relatively mild wind speeds and humidity levels. The average wind speed during this month ranges between 5 to 10 miles per hour, which can be categorized as a light breeze to gentle breeze on the Beaufort scale. This indicates that the wind usually does not cause any significant inconvenience or discomfort to residents and visitors.

The city sees a varying range of humidity levels in December, typically falling between 60% and 80% relative humidity. Higher humidity levels often occur in the early mornings, while afternoons tend to be drier. This fluctuation in humidity contributes to the overall comfortable climate that Austin is known for during the winter months.

It is important to note that while these averages provide a general sense of the wind and humidity conditions in December, specific conditions can vary day-to-day. Some days may experience higher winds or humidity levels, while others may be more mild. Nevertheless, Austin's December climate is generally consistent with these pattern, providing a pleasant environment for both indoor and outdoor activities.

Daylight and Twilight Conditions

In December, the city of Austin experiences varying daylight and twilight conditions. Due to its geographical location, daylight hours gradually decrease as the calendar progresses towards the winter solstice.

At the beginning of the month, Austin averages 10 hours and 21 minutes of daylight. As the month progresses, the day length continues to shorten, reaching its minimum on the winter solstice – around December 21st – with approximately 10 hours and 6 minutes of daylight.

The solar elevation angle in Austin during December ranges between 30 to 45 degrees at solar noon. This is the angle between the sun and the horizon, which indicates the sun's position in the sky. The azimuth, the angle between the sun and the observer's meridian, shifts closer to the southern direction during the winter months. This results in the sun remaining lower in the sky and casting longer shadows.

Twilight conditions in Austin during December consist of civil, nautical, and astronomical twilight. Civil twilight occurs when the solar elevation is between 0 and 6 degrees below the horizon; this is the period during which most outdoor activities can still be conducted without artificial lighting. Nautical twilight takes place when the solar elevation is between -6 and -12 degrees, making it difficult to distinguish the horizon at sea. Astronomical twilight is when the solar elevation is between -12 and -18 degrees; this is when the sky is dark enough for astronomers to observe celestial objects without interference from the sun's light.

In summary, December in Austin is characterized by shorter daylight hours and noticeable twilight conditions. As the month progresses, the sun remains lower in the sky, with solar elevation and azimuth angles leading to less direct sunlight and longer shadows. These factors contribute to the overall chilly temperatures and unique lighting conditions that Austin experiences during December.

Microclimate Variations

The Austin area is known to exhibit microclimate variations due to several factors including topography, urban development and its proximity to coastal areas. The MERRA-2 model-based reconstructions provide valuable insights into these variations and can help predict fluctuations in weather conditions.

Austin's microclimates often result from the interaction of diverse local factors. One such factor is the city's location, which is not too far from the coast. Coastal areas generally experience more moderate temperatures due to the influence of the ocean. In December, these coastal effects can make the Austin area marginally cooler, providing somewhat milder winter temperatures.

The city's topography introduces considerable variations in weather conditions. In particular, low-lying areas with higher humidity may experience cooler temperatures, while elevated regions, such as hills or mountains, can either trap cold air within valleys or receive more sunlight and warmth. These factors combine to create Austin's unique microclimates.

The influence of urban development on Austin's microclimate cannot be ignored. The urban heat island effect, caused by the presence of large concrete structures, absence of greenery, and waste heat generation, leads to higher temperatures within the dense city bounds. This effect is more pronounced during the day and can result in warmer temperatures compared to surrounding rural areas.

In conclusion, understanding the nuances of Austin's microclimate can be crucial in predicting temperature variations in December. The MERRA-2 model-based reconstructions serve as a valuable tool in this endeavor, allowing for an accurate representation of temperature and weather patterns. The amalgamation of coastal influences, Austin's topography, and urban development all culminate in creating the unique microclimates present within the city.

Weather Station Observations

Austin's temperature in December can be best studied by analyzing the data collected from weather stations, including the Austin-Bergstrom International Airport (ABIA) station. The ABIA weather station is one of the most reliable sources of information due to its consistent monitoring and modern equipment.

The weather observations at the airport indicate an average temperature range of 41-62°F (5-17°C) in December. These observed temperatures have been on a consistent rise in the past few years, hinting at the impact of climate change on the region. The collected data also showcases temperature variations during the course of December, with the occasional cold front passing through and causing temporary dips in temperature.

In addition to the ABIA station, other nearby weather stations provide valuable insights into Austin's December climate. These include the Camp Mabry station and the Del Valle station, which have tracked similar trends in December temperature fluctuations. A comparative analysis of the stations supports the conclusion that weather patterns in Austin are reasonably homogenous throughout the region.

Austin-Bergstrom International Airport: Average temperature range of 41-62°F (5-17°C)
Camp Mabry station: Displays similar temperature trends as the ABIA station
