Weather in August

August holds the summer heat steady with slight variations from July. Even though the temperature marginally lowers to a maximum of 87.1°F (30.6°C), there is hardly any significant relief from the summer heat. This drop loosely coincides with a decrease in the duration of daylight and sunshine hours. Despite these changes, the UV index only slightly falls to 6, still presenting intense solar radiation. The balance of heat and sunlight persists, rendering an interesting yet vibrant summer atmosphere.

Temperature

The shift from July to August is characterized by an average high-temperature of a still tropical 87.1°F (30.6°C), not significantly different from the 89.2°F (31.8°C) of July. An average nighttime temperature of 67.6°F (19.8°C) is observed during August.

Heat index

The heat index in August is appraised at a fiery hot 98.6°F (37°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
