Weather in September
Temperature
Njwejwe starts September with an average high-temperature of a still moderately hot 28°C (82.4°F), hinting at a minimal fluctuation from August. An average nighttime temperature of 16.6°C (61.9°F) is observed during September.Heat index
For September, the heat index is computed to be a tropical 32°C (89.6°F). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Consider that heat index readings are for situations in the shade and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. 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. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.

Guard oneself from overexposure. Defence against sun injury is vital. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
