Heat index

The heat index in January is evaluated at a tropical 31°C (87.8°F). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.
Always consider that heat index estimations are for light winds and places in the shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage. Heads up! UV intensity is amplified by reflections from water and sand.
