Heat index

The average heat index in June is evaluated at an extremely hot 41°C (105.8°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

The average relative humidity in June is 75%.

Guard against overexposure. Protection from sun-induced harm is essential. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
