Heat index

The heat index in August is estimated at a sweltering 38°C (100.4°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Without proper safety measures, skin and eyes can be quickly harmed. Be sure to protect yourself. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades. Regardless of cloud cover, it's recommended to apply generously and reapply often a sunscreen with an SPF of at least 30, especially after swimming or any outdoor activity.
