Weather in August
Temperature
August's arrival brings an average high-temperature of a still tropical 90.3°F (32.4°C), slightly deviating from July's 91.8°F (33.2°C). Throughout August, Dyson experiences a low-temperature average of 69.8°F (21°C).Heat index
For most parts of August, the heat index is evaluated at an extremely hot 107.6°F (42°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

The months with the highest UV index are June and August, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for average individuals.Note: The daily maximum UV index of 7 in August interprets into the following advice:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
