Weather in August
Temperature
The advent of August presents an average high-temperature of a moderately hot 85.6°F (29.8°C), maintaining a close correlation with the preceding month. During August, Arthur observes a consistent average nighttime temperature of 66.7°F (19.3°C).Heat index
The heat index value during August is computed to be a sweltering 96.8°F (36°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via 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. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
