Weather in January
Temperature
The arrival of January sees an average high-temperature of a still warm 27°C (80.6°F), hardly diverging from December's 27.5°C (81.5°F). The temperature during January sees a subtle transition from day to night, averaging a low of 25.3°C (77.5°F).Heat index
During January, the heat index is estimated at 29°C (84.2°F). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
