Weather in January
Temperature
Santíssimo's average high-temperature in January sits at a tropical 30.1°C (86.2°F), showing little difference from the previous month. Throughout January nights, Santíssimo experiences a consistent temperature average of 21.6°C (70.9°F).Heat index
For most parts of January, the heat index is calculated to be a torrid 38°C (100.4°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
