Weather in September
Temperature
September's average high-temperature stands at a still tropical 32.6°C (90.7°F), showing little deviation from August's 31.8°C (89.2°F). In Klakahrejo, the average low-temperature during the month of September is a warm 24.3°C (75.7°F).Heat index
During September, the heat index is calculated to be a blistering 40°C (104°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
