Weather in September
Temperature
September's commencement is accompanied by an average high-temperature of a still moderately hot 28.1°C (82.6°F), diverging marginally from August's 27.9°C (82.2°F). Gwaunaruu, during the September nights, maintains an average temperature of 25.8°C (78.4°F), closely aligned with its daytime readings.Heat index
The average heat index in September is computed to be a hot 33°C (91.4°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak.
