Justina experiences an average high-temperature of a still hot 91°F (32.8°C) in August, marking an insignificant shift from 91.2°F (32.9°C) in July. An average low-temperature of 73°F (22.8°C) is observed during August nights.

Heat index

Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
