Precipitation

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

The wetter season lasts 211 days, from October 25 to May 24, with a greater than 27% chance of a given day being a wet day. The chance of a wet day peaks at 42% on February 20.

The drier season lasts 154 days, from May 24 to October 25. The smallest chance of a wet day is 12% on July 29.

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 42% on February 20.

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. Gold Coast experiences very significant seasonal variation in monthly rainfall.

Rain falls throughout the year in Gold Coast. The most rain falls during the 31 days centered around February 8, with an average total accumulation of 6.0 inches.

The least rain falls around August 2, with and average total accumulation of 1.4 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.

Gold Coast experiences very significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 174 days, from October 26 to April 18, during which time the comfort level is muggy, oppressive, or miserable at least 18% of the time. The muggiest day of the year is February 4, with muggy conditions 72% of the time.

The least muggy day of the year is August 1, when muggy conditions are essentially unheard of.

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 Gold Coast does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 6.3 miles per hour throughout.

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 Gold Coast varies throughout the year.

The wind is most often from the south for 139 days, from April 9 to August 26, with a peak percentage of 45% on June 18. The wind is most often from the north for 115 days, from August 26 to December 19, with a peak percentage of 43% on December 11. The wind is most often from the east for 111 days, from December 19 to April 9, with a peak percentage of 53% on March 5.

Water Temperature

Gold Coast 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 107 days, from December 24 to April 10, with an average temperature above 77°F. The day of the year with the warmest water is February 13, with an average temperature of 79°F.

The time of year with cooler water lasts for 104 days, from June 26 to October 8, with an average temperature below 72°F. The day of the year with the coolest water is August 11, with an average temperature of 70°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 118 days, from October 24 to February 19, with an average daily incident shortwave energy per square meter above 6.7 kWh. The brightest day of the year is January 1, with an average of 7.6 kWh.

Data Sources

This report illustrates the typical weather in Gold Coast, 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 Gold Coast.

For each station, the records are corrected for the elevation difference between that station and Gold Coast 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 Gold Coast is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Gold Coast and a given station.

The stations contributing to this reconstruction are: Gold Coast Airport (85%, 20 kilometers, south) and Archerfield Aerodrome (15%, 63 kilometers, northwest).

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.
