Weather in August
Temperature
The average high-temperature in August, at a still hot 88.3°F (31.3°C), reveals a modest deviation from July's 88.7°F (31.5°C). The temperature lowers to an average of 77.4°F (25.2°C) during August nights.Heat index
Throughout August, the heat index is appraised at a blistering 105.8°F (41°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy 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 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
