Weather in January
Temperature
A minimal variation is noted in Cebadilla's average high-temperature at the onset of January, reaching a tropical 30.8°C (87.4°F) from December's 29.7°C (85.5°F). In Cebadilla, an average temperature of 21.9°C (71.4°F) is noted during January nights.Heat index
The heat index for January is computed to be a fiery hot 36°C (96.8°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

January through September and December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for average individuals.Note: In January, a daily maximum UV index of 7 leads to the following instructions:
Deter overexposure. Protecting against the sun's effects is essential. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
