Weather in August
Temperature
August ushers in an average high-temperature of a still tropical 32.4°C (90.3°F), aligning closely with the preceding month. The average temperature during August nights dips to a warm 24.1°C (75.4°F).Heat index
The heat index for August is calculated to be a blazing hot 45°C (113°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. Note! Reflective surfaces like sand and water heighten the UV radiation levels.
