Weather in August

August's heat index is appraised at a torrid 95°F (35°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
