Weather in September
Temperature
Chilonwa indicates an average high-temperature of a hot 30.5°C (86.9°F) in September, showing minor variation from August's 28.7°C (83.7°F). September nights present a sharp contrast to daytime highs, with average temperatures of 16.4°C (61.5°F).Heat index
For most parts of September, the heat index is computed to be a tropical 32°C (89.6°F). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
