Weather in August
Temperature
August, with its average high-temperature of 34.7°C (94.5°F) and an average low-temperature of 17.8°C (64°F), holds the record as the warmest month.Heat index
The heat index value during August is estimated at a fiery hot 39°C (102.2°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. 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. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for the average person.Note: The maximum UV index, 7 during August, leads to the following recommendations:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
