Upon the beginning of September, Wilgoda's high-temperatures register at a still tropical 31.2°C (88.2°F), closely mirroring the preceding month. Wilgoda's nighttime temperature in September drops to an average of 22.3°C (72.1°F).

Heat index

For most parts of September, the heat index is evaluated at a very hot 39°C (102.2°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 significance 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Prevent overexposure. Protection from the sun's harmful effects is needed.

Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
