Heat index

The average heat index in August is computed to be a blistering 43°C (109.4°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
Know that the heat index computations account for shaded terrains and slight winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Practice every essential safety step. People with fair skin could receive burns in fewer than 5 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Even if it's cloudy, generously apply and frequently reapply a sunscreen with no less than a 30 sun protection factor after each swim or outdoor exercise. Watch out! Reflections from sand and water can surge UV radiation exposure.
