Weather in January
Temperature
As San Andrés welcomes January, the average high-temperature stabilizes at a still warm 27.1°C (80.8°F), showing little deviation from December's 27.9°C (82.2°F). San Andrés nights in January witness a mild cool down to an average temperature of 26.4°C (79.5°F).Heat index
For most parts of January, the heat index is evaluated at a hot 30°C (86°F). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
