Weather in January

January is the month when Guánica experiences its coldest temperatures, averaging a high of 81.9°F (27.7°C) and a low of 72°F (22.2°C).Heat index
The heat index in January is evaluated at a tropical 87.8°F (31°C). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
