Weather in September
Temperature
The arrival of September marks a slight shift to an average high-temperature of a still tropical 32.4°C (90.3°F) from August's 31.8°C (89.2°F). During September, Hacienda San Juan's temperature records a considerable difference from its daily highs to an average low of 20.3°C (68.5°F).Heat index
September's mean heat index is computed to be a scorching 42°C (107.6°F). 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. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. 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. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
