Heat index

The heat index value during July is calculated to be an extremely hot 43°C (109.4°F). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
