Weather in September
Temperature
September begins with an average high-temperature of a still tropical 32.6°C (90.7°F), reflecting close similarity to the preceding month. Diayane observes an average nighttime low-temperature of 25.7°C (78.3°F) during the month of September.Heat index
Throughout September, the heat index is estimated at a scorching 44°C (111.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 highly critical for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
