Weather in January
Temperature
The commencement of January records an average high-temperature of a still tropical 30°C (86°F), barely varying from December's 31°C (87.8°F). Throughout January, Colo records an average temperature of 24.5°C (76.1°F) at night.Heat index
In January, the heat index is computed to be a very hot 38°C (100.4°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
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. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Ward off overexposure. Defence against solar harm is crucial. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
