Temperature

Diosso marks the onset of January with an average high-temperature of a still warm 29.3°C (84.7°F), a subtle shift from December's 28.5°C (83.3°F). Diosso maintains a minor drop in temperature during January nights, with averages of 25.3°C (77.5°F).

Heat index

January's mean heat index is evaluated at a very hot 36°C (96.8°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
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. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Note: A daily high UV index of 7 in January leads to these guidelines:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
