Weather in September
Temperature
September's climate shows a minor adjustment in average high-temperatures to a still tropical 33.6°C (92.5°F) from August's 32.3°C (90.1°F). Jemirahan experiences an average temperature drop to a pleasant 22.4°C (72.3°F) during September nights.Heat index
September's heat index is computed to be a blistering 42°C (107.6°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', arises from combining readings of air temperature and relative moisture content. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
