Weather in January
Temperature
January is the month that records the lowest temperatures, with averages ranging from a high of 29.7°C (85.5°F) to a low of 24.8°C (76.6°F).Heat index
The heat index value during January is computed to be a very hot 36°C (96.8°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.In terms of the heat index, values are set with light wind and shade conditions in mind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
