Weather in August
Temperature
The advent of August brings an average high-temperature of a still hot 86°F (30°C), exhibiting minor difference from the previous month. Unionville's August nights bring a significant temperature shift, averaging at an enjoyable 64.4°F (18°C).Heat index
August's mean heat index is estimated at a sweltering 96.8°F (36°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree 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 of high significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
