Weather in January
Temperature
The coldest period tends to be January, when average temperatures fluctuate between a high of 28.8°C (83.8°F) and a low of 24.3°C (75.7°F).Heat index
The average heat index in January is computed to be a tropical 32°C (89.6°F). If one remains active during constant exposure, it might cause exhaustion and heat cramps.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance 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.
