December weather forecast
Kowo, Indonesia

The first month of the summer, December, is still a warm month in Kowo, Indonesia, with an average temperature fluctuating between 24.5°C (76.1°F) and 29.5°C (85.1°F).

Temperature

The average high-temperature is a moderately hot 29.5°C (85.1°F) in December, hardly different from the 30.5°C (86.9°F) recorded in November. December witnesses a minor deviation from daytime peaks, with an average nighttime temperature of 24.5°C (76.1°F).

Heat index

For most parts of December, the heat index is calculated to be a very hot 37°C (98.6°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

UV index

January through May, September through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for ordinary individuals.
Note: A daily maximum UV index of 7 in December translates into the following instructions:
Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
