Weather in September
Temperature
The beginning of September records an average high-temperature of a still tropical 32.2°C (90°F), almost echoing the conditions of the previous month. During September, the temperature is averaged to a low of 23.2°C (73.8°F) at night.Heat index
September's mean heat index is appraised at a blisteringly hot 43°C (109.4°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
