Heat index

The heat index for August is appraised at a sweltering 96.8°F (36°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
The metrics for the heat index are tailored for both shady environments and light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In August, the average relative humidity is 78%.

UV index

May through November, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the average person.
Note: The maximum UV index of 7 during August translates into these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
