Weather in January
Temperature
In January, the average high-temperature registers at a tropical 30.6°C (87.1°F), nearly identical to December's 29.9°C (85.8°F). In January, Ateos experiences a temperature dip to an average of 19.4°C (66.9°F) at night.Heat index
The heat index for January is calculated to be a sweltering 35°C (95°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
Humidity
In Ateos, the average relative humidity in January is 65%.Rainfall
The month with the least rainfall is January, when the rain falls for 1.9 days and typically collects 1mm (0.04") of precipitation.Daylight

The months with the lowest UV index are January, May, June, August through December, with an average maximum UV index of 6. 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 maximum UV index, 6 during January, leads to the following recommendations:
Fend off overexposure. Sun protection is vital. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
