Heat index

The heat index for July is calculated to be a burning hot 118.4°F (48°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.
Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

During bright days, sunglasses that offer UVA and UVB defense are recommended.
