Heat index

The heat index in January is evaluated at a torrid 38°C (100.4°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Humidity

In January, the average relative humidity is 73%.

The months with the lowest UV index are January through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for average individuals.
Note: In January, a regular UV index of 7 translates into these guidelines:
Shun overexposure. Protection from sun ravages is indispensable. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
