Weather in August
Temperature
August ushers in an average high-temperature of a still tropical 89.4°F (31.9°C), aligning closely with the preceding month. The average temperature drops to an agreeable 71.8°F (22.1°C) during the night in the month of August.Heat index
August's mean heat index is estimated at a blistering 107.6°F (42°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
