January weather forecast
Ossu, East Timor

In Ossu, East Timor, the first month of the year is characterized by warm temperatures, significant moisture content in the air, and frequent rainfall. This period experiences a maximal amount of rainfall, averaging 88mm (3.46"), significantly higher in comparison to the immediate next months. January’s weather, marked by increased cloud formation and subsequent rains, often results in shorter sunlight hours, limiting the time for outdoor activities. Wind speeds are also relatively moderate, contributing to the pleasant, slightly humid, tropical climate. A distinct feature noticed this month is the limited visibility, compared to the remaining months of the year.

Temperature

Ossu's shift into January is marked by a subtle change to a warm 29°C (84.2°F) from December's 30°C (86°F) in temperature. Ossu's nighttime temperatures in January reveal a minimal variation from the daytime highs, averaging at a still moderately hot 24.2°C (75.6°F).

Heat index

In January, the average heat index is evaluated at a sweltering 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. 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', comes about by integrating the temperature readings with the humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

In Ossu, the average relative humidity in January is 83%.

Sunshine

January has the least sunshine of the year, with an average of 7.3h of sunshine.

UV index

The months with the highest UV index are January through March, September through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: In January, the average maximum UV index of 7 translates into the following recommendations:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. To cut down UV radiation exposure by about half, sport a wide-brim hat.
