Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a still moderately hot 29.5°C (85.1°F), from a not significantly different 28.8°C (83.8°F). Tomono, during the nights of September, experiences an average temperature drop to a pleasant 21.6°C (70.9°F).Heat index
The heat index for September is computed to be a sweltering 37°C (98.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
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 including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
