Weather in August
Temperature
The transition into August marks the average high-temperature at a still tropical 92.1°F (33.4°C), differing minimally from July's 93°F (33.9°C). With a significant temperature contrast, nighttime temperatures hover around an average low of 69.6°F (20.9°C) in August.Heat index
August's mean heat index is computed to be a blistering 111.2°F (44°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Heat index determinations are made taking into account the shade and light air movements. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
