Weather in January
Temperature
The shift from December to January is characterized by an average high-temperature of a still warm 27.8°C (82°F), not significantly different from the 26.7°C (80.1°F) of December. An average temperature of 20.5°C (68.9°F) is recorded during the nights in January.Heat index
During January, the heat index is computed to be a tropical 32°C (89.6°F). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.For clarity, heat index numbers account for light winds and areas under shade. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
