Heat index

The heat index in December is calculated to be a hot 33°C (91.4°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.

Never neglect to protect yourself. Eyes and skin can suffer swift damage. 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. Stay sun-safe with clothing that is both closely woven and worn loosely. Use liberally and reapply a broad-spectrum sunscreen with at least SPF 30 every two hours and right after outdoor activities or a swim. Attention! UV radiation is ramped up when reflecting off sand and water surfaces.
