As the rainfall reduces and the pressure stabilizes, overall temperatures and wind conditions create a favorable environment for various outdoor activities.

Temperature

Transitioning into August, Wempi records an average high-temperature of a still hot 32.8°C (91°F), almost identical to July's 31.1°C (88°F). The August nights bear witness to a significant drop from the daytime highs, settling at an average temperature of 20.5°C (68.9°F).

Heat index

For August, the heat index is computed to be a burning hot 47°C (116.6°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

UV index

August through November, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.
Note: An average maximum UV index of 7 in August leads to these recommendations:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
