Weather in January
Temperature
Fortim experiences a minor change to a still tropical 31.1°C (88°F) in average high-temperature during January, closely reflecting December. In the month of January, the average temperature dips to a moderately hot 25.7°C (78.3°F) during the night.Heat index
The heat index value during January is computed to be a very hot 38°C (100.4°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: The maximum daily UV index, 7 in January, converts into the following recommendations:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. 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. Enhance your sun protection with tightly woven, yet airy clothing.
