Weather in August
Temperature
The arrival of August denotes a barely perceptible change in the average high-temperatures to a still hot 88.3°F (31.3°C) from July's 89.4°F (31.9°C). In the month of August, the nighttime temperature dips to a steady average of 69.4°F (20.8°C).Heat index
The heat index value during August is estimated at a blistering 104°F (40°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
