Weather in January
Temperature
The coldest period is January, when temperatures fluctuate between an average high of 29.6°C (85.3°F) and a low of 25.6°C (78.1°F).Heat index
In January, the heat index is calculated to be a sweltering 35°C (95°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the average person.Note: The daily high UV index of 7 in January translates into this advice:
Prevent overexposure. Protection from the sun's harmful effects is needed. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
