Weather in January
Temperature
Mendewa greets January with an average high-temperature of a still tropical 34.8°C (94.6°F), marking a slight deviation from the preceding month. Mendewa sees a consistent average low-temperature of 20.1°C (68.2°F) in January, indicating a substantial decrease from the day's temperature.Heat index
Throughout January, the heat index is calculated to be a blazing hot 48°C (118.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Heat index determinations are made taking into account the shade and light air movements. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
Humidity
The average relative humidity in January is 67%.Rainfall
The month with the least rainfall is January, when the rain falls for 4.3 days and typically collects 5mm (0.2") of precipitation.Daylight

Sunshine

The months with the highest UV index are January through April, November and December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for the ordinary person.Note: In January, the UV index of 7 transforms into the following advice:
Guard against overexposure. Protection from sun-induced harm is essential. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
