December Weather in Fiji FijiDaily high temperatures are around 85°F, rarely falling below 81°F or exceeding 89°F. Daily low temperatures are around 74°F, rarely falling below 69°F or exceeding 78°F. For reference, on February 22, the hottest day of the year, temperatures in Fiji typically range from 75°F to 87°F, while on August 23, the coldest day of the year, they range from 68°F to 78°F. The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on December. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. CloudsThe month of December in Fiji experiences gradually increasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy increasing from 70% to 77%. The clearest day of the month is December 2, with clear, mostly clear, or partly cloudy conditions 31% of the time. For reference, on February 28, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 81%, while on August 19, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 62%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Fiji, the chance of a wet day over the course of December is very rapidly increasing, starting the month at 40% and ending it at 48%. For reference, the year's highest daily chance of a wet day is 57% on February 10, and its lowest chance is 18% on July 6. RainfallTo show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during December in Fiji is rapidly increasing, starting the month at 6.6 inches, when it rarely exceeds 12.4 inches or falls below 2.1 inches, and ending the month at 8.0 inches, when it rarely exceeds 13.7 inches or falls below 3.0 inches. SunOver the course of December in Fiji, the length of the day is essentially constant. The shortest day of the month is December 1, with 13 hours, 8 minutes of daylight and the longest day is December 21, with 13 hours, 13 minutes of daylight. The earliest sunrise of the month in Fiji is 5:23 AM on December 1 and the latest sunrise is 12 minutes later at 5:35 AM on December 31. The earliest sunset is 6:30 PM on December 1 and the latest sunset is 16 minutes later at 6:46 PM on December 31. Daylight saving time is not observed in Fiji during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 5:29 AM and sets 13 hours, 13 minutes later, at 6:42 PM, while on June 20, the shortest day of the year, it rises at 6:38 AM and sets 11 hours, 3 minutes later, at 5:41 PM. The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation. MoonThe figure below presents a compact representation of key lunar data for December 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.
HumidityWe base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night. The chance that a given day will be muggy in Fiji is essentially constant during December, remaining within 1% of 99% throughout. For reference, on February 5, the muggiest day of the year, there are muggy conditions 100% of the time, while on August 26, the least muggy day of the year, there are muggy conditions 67% of the time. WindThis section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages. The average hourly wind speed in Fiji is essentially constant during December, remaining within 0.3 miles per hour of 12.3 miles per hour throughout. For reference, on August 4, the windiest day of the year, the daily average wind speed is 13.4 miles per hour, while on February 18, the calmest day of the year, the daily average wind speed is 11.1 miles per hour. The hourly average wind direction in Fiji throughout December is predominantly from the east, with a peak proportion of 71% on December 17. Water TemperatureFiji is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water. The average surface water temperature in Fiji is essentially constant during December, remaining within 1°F of 81°F throughout. Growing SeasonDefinitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). Temperatures in Fiji are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F. The average accumulated growing degree days in Fiji are rapidly increasing during December, increasing by 860°F, from 3,748°F to 4,608°F, over the course of the month. Solar EnergyThis section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation. The average daily incident shortwave solar energy in Fiji is essentially constant during December, remaining within 0.1 kWh of 6.3 kWh throughout. TopographyFor the purposes of this report, the geographical coordinates of Fiji are -18.000 deg latitude, 178.000 deg longitude, and 0 ft elevation. The topography within 2 miles of Fiji is essentially flat, with a maximum elevation change of 0 feet and an average elevation above sea level of 0 feet. Within 10 miles is also essentially flat (0 feet). Within 50 miles is also essentially flat (0 feet). The area within 2 miles of Fiji is covered by trees (84%), within 10 miles by trees (82%), and within 50 miles by water (51%) and trees (30%). Data SourcesThis report illustrates the typical weather in Fiji, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

DisclaimerThe information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
