Weather in September
Temperature
The start of September marks an average high-temperature of a still hot 31.3°C (88.3°F), hardly distinguishable from the conditions in August. Throughout September, Maseng experiences a low-temperature average of 22.2°C (72°F).Heat index
September's average heat index is appraised at a sweltering 38°C (100.4°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
