Weather in August
Temperature
Cullen experiences a minor change to a still tropical 94.5°F (34.7°C) in average high-temperature during August, closely reflecting July. Cullen receives a consistent average low-temperature of 72.1°F (22.3°C) in August, a substantial dip from the day's heat.Heat index
In August, the average heat index is appraised at a burning hot 118.4°F (48°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Heat index evaluations are typically in the context of light winds and shaded environments. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
