Weather in September

September heralds a minor drop in average high-temperature, sliding from August's tropical 91.8°F (33.2°C) to a warm 85.3°F (29.6°C). Throughout the month of September, Fort Hancock witnesses an average low-temperature of 68.7°F (20.4°C).Heat index

Prolonged exercise may result in heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
