Weather in September
Temperature
Letsitele starts September with an average high-temperature of a still warm 29.5°C (85.1°F), a minor shift from August's 27°C (80.6°F). With a significant temperature contrast, nighttime temperatures hover around an average low of 17.3°C (63.1°F) in September.Heat index
For most parts of September, the heat index is calculated to be a hot 30°C (86°F). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
