Weather in January
Temperature
January tends to be the coldest month, with temperatures averaging a daily high of 27.3°C (81.1°F) and a low of 19.8°C (67.6°F).Heat index
In January, the heat index is calculated to be a tropical 31°C (87.8°F). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital 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.
