Heat index

The heat index value during July is evaluated at a fiery hot 36°C (96.8°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. As body temperatures escalate without effective heat release, one might face dehydration threats.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
