Weather in January
Temperature
Santa Clotilde, São Tomé and Príncipe, marks the arrival of January with an average high-temperature of a still moderately hot 28°C (82.4°F), hardly different from December's 27.5°C (81.5°F). Nights in January in Santa Clotilde exhibit a minor reduction to an average low temperature of 27°C (80.6°F).Heat index
January's average heat index is computed to be a tropical 32°C (89.6°F). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.Know that the heat index computations account for shaded terrains and slight winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 particularly relevant to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
