Weather in December
Temperature
The warmest period tends to be December, when average temperatures fluctuate between a high of 29.3°C (84.7°F) and a low of 24°C (75.2°F).Heat index
In December, the average heat index is evaluated at a torrid 37°C (98.6°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Note that heat index values are valued for light wind and location in the shade. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
Humidity
In December, the average relative humidity is 84%.Rainfall
The wettest months are March and December, with an average 299mm (11.77") of rainfall.Sea temperature
In Honiara, the average seawater temperature in December is 30.2°C (86.4°F).Note: One could argue that swimming in waters above 30°C (86°F) lacks the desired refreshing touch.

Sunshine

January through March, June, August, October through December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from unprotected exposure to Sun's UV rays for the average person.Note: The maximum UV index of 6 during December leads to these instructions:
Stay clear of intense sun exposure. Solar protection is of utmost significance. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
