Weather in September
Temperature
With the onset of September, a modest change to a still tropical 86.7°F (30.4°C) from August's 90.7°F (32.6°C) is noted in high-temperature. Throughout September, Rafn encounters an average temperature drop to a comfortable 67.8°F (19.9°C).Heat index
September's heat index is estimated at a sweltering 100.4°F (38°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
