August weather forecast
Amarillo, TX

August retains the momentum of the summer's intense heat but also signifies the beginning of its gradual decline. While temperatures are nearly identical to those of July, a slight decrease in rainfall is recorded. This time also boasts the maximum wind speed of the year hitting a high gust of 16.3mph (26.2km/h). The high winds, combined with continually high temperatures create an atmosphere of desert-like dryness. On the whole, August offers a uniquely Texan summer experience with its medley of warm and dry days.

Temperature

August's onset brings an average high-temperature of a still hot 91.8°F (33.2°C), showing a minute difference from July's 92.8°F (33.8°C). A stark contrast in day to night temperatures can be seen in August, with an average low-temperature of 70°F (21.1°C).

Heat index

In August, the average heat index is calculated to be a fiery hot 96.8°F (36°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Understanding the heat index involves considering values for shaded locales with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
