Weather in September
Temperature
September's onset records a minor alteration in the average high-temperature to a still tropical 32.4°C (90.3°F) from August's 32.6°C (90.7°F). In the month of September, Naljani's average low-temperature falls to a moderately hot 25.7°C (78.3°F).Heat index
September's mean heat index is appraised at a life-threatening hot 46°C (114.8°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.Note that heat index values are valued for light wind and location in the shade. 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 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
