Weather in August
Temperature
August reports an average high-temperature of a still tropical 33.4°C (92.1°F), slightly varied from July's 31.8°C (89.2°F). In August, the recorded average low-temperature, of 21.3°C (70.3°F), exhibits a significant fall from the daytime highs.Heat index
During August, the heat index is calculated to be a sweltering 39°C (102.2°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Realize that the values for the heat index are set for shaded places and light winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
