During July, the heat index is calculated to be an extremely hot 44°C. Stay watchful
: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.
Heat index determinations are made taking into account the shade and light air movements. 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 'feels like' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Ensure every key safety measure. People with light skin might sustain burns in fewer than 5 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Always opt for UVA and UVB-resistant sunglasses on radiant days. Prompt application of a broad-spectrum sunscreen, SPF 30+, is necessary after a swim or an outdoor workout and it should be re-applied every two hours. Attention! The combination of sand and water reflections enhances UV ray intensity.
