Weather in September
Temperature
Corpus Christi's weather in September indicates an average high-temperature of a still tropical 89.6°F (32°C), nearly consistent with the 94.1°F (34.5°C) of August. In Corpus Christi, in September, the average low-temperature is a warm 76.8°F (24.9°C).Heat index
In September, the average heat index is calculated to be a blistering 104°F (40°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Records show heat index calculations are tailored for shaded regions and mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
