Heat index

The heat index for July is estimated at a sweltering 100.4°F (38°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their 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 particularly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Resist extreme sun exposure. Guarding against solar damage is essential. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
