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

The wetter season lasts 8.9 months, from September 29 to June 27, with a greater than 22% chance of a given day being a wet day. The chance of a wet day peaks at 29% on January 31.

The drier season lasts 3.1 months, from June 27 to September 29. The smallest chance of a wet day is 15% on July 30.

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 29% on January 31.

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 of the year. Ulladulla experiences some seasonal variation in monthly rainfall.

Rain falls throughout the year in Ulladulla. The most rain falls during the 31 days centered around February 8, with an average total accumulation of 3.7 inches.

The least rain falls around August 10, with an average total accumulation of 2.1 inches.

Daylight saving time (DST) is observed in Ulladulla during 2017, starting in the spring on October 1 and ending in the fall on April 2.

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.

Ulladulla experiences significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 3.8 months, from December 4 to March 29, during which time the comfort level is muggy, oppressive, or miserable at least 9% of the time. The muggiest day of the year is February 1, with muggy conditions 34% of the time.

The least muggy day of the year is July 27, when muggy conditions are essentially unheard of.

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 predominant average hourly wind direction in Ulladulla varies throughout the year.

The wind is most often from the south for 1.5 months, from March 24 to May 7, with a peak percentage of 33% on April 17. The wind is most often from the west for 5.0 months, from May 7 to October 6, with a peak percentage of 52% on August 8. The wind is most often from the east for 4.3 months, from November 15 to March 24, with a peak percentage of 35% on January 1.

Temperature and Dew Point

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

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

The stations contributing to this reconstruction are: Nowra Ran Air Station (82%, 46 kilometers, north) and Canberra International Airport (18%, 116 kilometers, west).

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.
