Weather in January
Temperature
As December turns into January, the average high-temperatures rest at a still moderately hot 28°C (82.4°F), showing a minor variation from the prior month. January's average low temperature is a still warm 27°C (80.6°F), displaying a subtle drop from its daily peak.Heat index
In January, the average heat index is calculated to be a tropical 32°C (89.6°F). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
