The average high-temperature is a still tropical 87.1°F (30.6°C) in August, hardly different from the 88.9°F (31.6°C) recorded in July. An average low-temperature of 65.7°F (18.7°C) is anticipated throughout the nights during August.

Heat index

The heat index value for August is estimated at a sweltering 98.6°F (37°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. 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', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
