Temperature

August, marked by an average high-temperature of 87.8°F (31°C) and a low-temperature of 80.6°F (27°C), is the warmest month.

Heat index

During August, the heat index is calculated to be a fiery hot 102.2°F (39°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

UV index

The months with the highest UV index are May through September, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for ordinary individuals.
Note: In August, a regular UV index of 7 translates into these guidelines:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Stay aware! UV radiation is magnified when reflecting off sand and water.
