Weather in August
Temperature
With the onset of August, the average high-temperature registers at a still tropical 87.4°F (30.8°C), subtly different from July's 90°F (32.2°C). An average low-temperature of 67.1°F (19.5°C) is observed during August nights.Heat index
In August, the heat index is estimated at a sweltering 100.4°F (38°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
