Weather in January
Temperature
The onset of January notes an average high-temperature of a still moderately hot 27.5°C (81.5°F), subtly shifted from December's 27.7°C (81.9°F). Throughout January, the temperature tends to fall to a consistent average low of 18.9°C (66°F).Heat index
In January, the heat index is estimated at a hot 32°C (89.6°F). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
