Temperature

Mussulo experiences an average high-temperature of a still moderately hot 29.6°C (85.3°F) in January, subtly different from December's 28.9°C (84°F). In the month of January, Mussulo experiences a minor discrepancy from peak daytime temperatures, settling at an average low-temperature of 24.9°C (76.8°F).

Heat index

The heat index value during January is estimated at a very hot 36°C (96.8°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Humidity

In January, the average relative humidity is 79%.

UV index

January through April, October through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.
Note: The daily maximum UV index of 7 in January interprets into the following advice:
Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
