Weather in September
Temperature
The start of September sees the average high-temperature at a still warm 29.8°C (85.6°F), showing little difference from August's 29.4°C (84.9°F). Throughout September, the temperature in Gwane tends to fall to a consistent average low of 19.4°C (66.9°F).Heat index
For September, the heat index is estimated at a sweltering 38°C (100.4°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Remember, devices such as parasols or canopies might not provide complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
