Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Nouméa varies throughout the year.

The wetter season lasts 188 days, from December 20 to June 26, with a greater than 22% chance of a given day being a wet day. The chance of a wet day peaks at 35% on February 28.

The drier season lasts 177 days, from June 26 to December 20. The smallest chance of a wet day is 8% on October 7.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 35% on February 28.

Daily Chance of Precipitation

The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day).

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Nouméa experiences significant seasonal variation in monthly rainfall.

Rain falls throughout the year in Nouméa. The most rain falls during the 31 days centered around March 11, with an average total accumulation of 4.8 inches.

The least rain falls around October 5, with and average total accumulation of 0.9 inches.

Average Monthly Rainfall

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Humidity

We 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.

Nouméa experiences very significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 233 days, from October 18 to June 8, during which time the comfort level is muggy, oppressive, or miserable at least 31% of the time. The muggiest day of the year is February 21, with muggy conditions 97% of the time.

The least muggy day of the year is August 7, with muggy conditions 8% of the time.

Wind

This 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 Nouméa experiences mildly seasonal variation over the course of the year.

The windier part of the year lasts for 180 days, from December 20 to June 18, with average wind speeds of more than 7.2 miles per hour. The windiest day of the year is March 12, with an average hourly wind speed of 7.8 miles per hour.

The calmer time of year lasts for 185 days, from June 18 to December 20. The calmest day of the year is September 23, with an average hourly wind speed of 6.5 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Nouméa is from the east throughout the year.

Water Temperature

Nouméa 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 water temperature experiences some seasonal variation over the course of the year.

The time of year with warmer water lasts for 98 days, from January 2 to April 10, with an average temperature above 79°F. The day of the year with the warmest water is February 22, with an average temperature of 81°F.

The time of year with cooler water lasts for 105 days, from July 1 to October 14, with an average temperature below 74°F. The day of the year with the coolest water is August 21, with an average temperature of 72°F.

Solar Energy

This 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 experiences significant seasonal variation over the course of the year.

The brighter period of the year lasts for 119 days, from October 7 to February 3, with an average daily incident shortwave energy per square meter above 6.7 kWh. The brightest day of the year is December 4, with an average of 7.5 kWh.

Data Sources

This report illustrates the typical weather in Nouméa, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Nouméa.

For each station, the records are are corrected for the elevation difference between that station and Nouméa according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Nouméa is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Nouméa and a given station.

The stations contributing to this reconstruction are: Noumea Nlle-Caledonie (98%, 1.3 kilometers, northwest) and Île des Pins Airport (1.7%, 109 kilometers, east).

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
