Heat index

For October, the heat index is appraised at a life-threatening hot 48°C (118.4°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Refrain from exposing skin and eyes. Without protection, they can get damaged rapidly. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended. Sunscreen of at least SPF 30 should be applied generously and reapplied often on overcast days, especially post swim or outdoor exercise. Caution! The Sun's UV rays become stronger due to reflections from water and sand.
