January weather forecast
Jemirahan, Indonesia

January, like December, is another hot summer month in Jemirahan, Indonesia, with temperature in the range of an average low of 23.6°C (74.5°F) and an average high of 30.2°C (86.4°F).

Temperature

Jemirahan experiences an average high-temperature of a still tropical 30.2°C (86.4°F) in January, marking an insignificant shift from 31.5°C (88.7°F) in December. Throughout the month of January, Jemirahan witnesses an average low-temperature of 23.6°C (74.5°F).

Heat index

For January, the heat index is computed to be a torrid 39°C (102.2°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

The average relative humidity in January is 83%.

Rainfall

In Jemirahan, in January, it is raining for 30.1 days, with typically 261mm (10.28") of accumulated precipitation. Throughout the year, there are 218.1 rainfall days, and 1410mm (55.51") of precipitation is accumulated.

Sunshine

January has the least sunshine of the year, with an average of 7.1h of sunshine.

UV index

The months with the lowest UV index are January and March, with an average maximum UV index of 6. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: In January, a regular UV index of 6 translates into these guidelines:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
