Weather in September
Temperature
The average high-temperature during September is a still tropical 86°F (30°C), almost matching the conditions of the preceding month. September's nights observe an average temperature of 67.3°F (19.6°C).Heat index
The heat index in September is calculated to be a torrid 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index data is primarily for areas with shade and subjected to light winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
