Weather in January
Temperature
The transition from December to January sees average high-temperatures adjusting to a still moderately hot 27.3°C (81.1°F), from a not significantly different 26.5°C (79.7°F). Ron records a consistent low-temperature of 16.8°C (62.2°F) during January nights.Heat index
For most parts of January, the heat index is estimated at a tropical 30°C (86°F). With extended exposure and activity, one might feel exhausted and experience heat cramps.Note that heat index values are valued for light wind and location in the shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
