Weather in August
Temperature
As Jack transitions into August, the average high-temperature stands at a still hot 91.4°F (33°C), offering little variation from the preceding month. Throughout the month of August, Jack reports a steady low-temperature average of 72.1°F (22.3°C).Heat index
The average heat index in August is estimated at a burning hot 114.8°F (46°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. 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. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
