Competition Area

Uvalde is located in an area of proven, outstanding, consistent soaring where distance and closed-circuit flight of 322 km (200 miles) to 805 km (500 miles) are routine with speeds averaging up to 144 kph (90 mph). Uvalde has been the site of numerous regional and national soaring contests. 

To the South of this East/West line lies flat prairie-like plains, and to the North, hilly and uneven terrain. The task area is also bordered to the Southwest by Mexico. Ground elevation at Uvalde is 287 m (941 feet) above mean sea level.  

To the North lies the Texas Hill Country, where the surface rises to meet the Edward’s Plateau with elevations of 610 m (2000 feet) or more. The task is approximately 443 km (275 miles) long and 290 km (180 miles) wide, with Uvalde situated in the middle.

Meteorology and Topography

Ask any native Texan, and you can bet he or she is familiar with the old saying, “If you don’t like the weather in Texas, wait a minute.” While a bit of an exaggeration, the State does not experience a great deal of weather variability from one day to the next, at least during the cooler months of the year. 

The variability is not temporal, though. Dry continental air flows off the mountains of West Texas and Northern New Mexico as marine air spreads Northward from the nearby Gulf of Mexico. Add to this the occasional intrusion of cooler air from the North being channeled along the elevated terrain of West Texas, and you have the makings of the most diverse weather you are likely to find anywhere in the world. If there is any predictability in Texas weather, it would have to be in summer when persistence often is the rule. This is especially true for a South Texas region that extends eastward from the Rio Grande River across the Edward’s Plateau (and Hill Country, which is not shown but comprises the Eastern third of the Edward’s Plateau) and Rio Grande Plain. Hot conditions with a general lack of precipitation prevail but occasionally give way to disturbance to break the weather cycle. 

Fortunately, this persistence results in some of the ideal thermal soaring conditions around for the soaring enthusiast. Abundant sunshine, light wind throughout the atmosphere, and a deep mixing layer all characterize typical summer conditions across the region of South Texas. In what follows, we will take a close look at the climatology of summer conditions across this region of South Texas, especially related to the sport of soaring. Additionally, we will offer a discussion of the sea breeze circulation patterns and associated weather, which at times, can play havoc with soaring in this region of the world.
