Weather in September
Temperature
The advent of September sees the average high-temperature at a still hot 30.4°C (86.7°F), subtly shifted from August's 30.2°C (86.4°F). Manado Tua Dua in September experiences a low-temperature average of 24°C (75.2°F).Heat index
In September, the average heat index is evaluated at a sweltering 38°C (100.4°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
