Weather in January
Temperature
With the onset of January, a modest change to a tropical 30.3°C (86.5°F) from December's 29.5°C (85.1°F) is noted in high-temperature. The nighttime temperature dips to an agreeable 21.1°C (70°F) on average during January.Heat index
The heat index for January is computed to be a sweltering 36°C (96.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Ward off overexposure. Defence against solar harm is crucial. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
