Heat index

For June, the heat index is appraised at a blazing hot 53°C (127.4°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Note that heat index values are valued for light wind and location in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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 and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Keep in mind that shade structures may not provide complete protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
