Weather in December
Temperature
In Honiara, the peak temperatures are generally noted in December, averaging a high of 29.3°C (84.7°F) and a low of 24°C (75.2°F).Heat index
For December, the heat index is computed to be a torrid 37°C (98.6°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
Humidity
The average relative humidity in December is 84%.Rainfall
The months with the most rainfall are March and December, with an average 299mm (11.77") of precipitation.Sea temperature
In December, the average sea temperature is 30.2°C (86.4°F).Note: Many feel that waters warmer than 30°C (86°F) fail to offer the same rejuvenating touch.
Daylight
With an average of 12h and 42min of daylight, December has the longest days of the year.On the first day of the month, sunrise is at 05:50 and sunset at 18:28. On the last day of December, in Honiara, sunrise is at 06:03 and sunset at 18:43 +11.
Sunshine
In Honiara, the average sunshine in December is 8.9h.UV index
January through March, June, August, October through December, with an average maximum UV index of 6, are months with the lowest UV index in Honiara. 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: A daily maximum UV index of 6 in December translates into the following instructions:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Stay vigilant! UV rays get a boost in intensity due to sand and water reflections.
