Weather in September
Temperature
The advent of September denotes an average high-temperature of a still tropical 87.3°F (30.7°C), subtly different from August's 90.9°F (32.7°C). Innis's average low-temperature during September nights is observed to be a pleasant 69.1°F (20.6°C).Heat index
The heat index for September is appraised at a blisteringly hot 104°F (40°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. 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. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
