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

The wetter season lasts 5.1 months, from May 8 to October 10, with a greater than 18% chance of a given day being a wet day. The chance of a wet day peaks at 30% on August 18.

The drier season lasts 6.9 months, from October 10 to May 8. The smallest chance of a wet day is 5% on February 11.

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 30% on August 18.

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. Mundulla experiences some seasonal variation in monthly rainfall.

Rain falls throughout the year in Mundulla. The most rain falls during the 31 days centered around June 25, with an average total accumulation of 1.9 inches.

The least rain falls around February 13, with an average total accumulation of 0.5 inches.

Daylight saving time (DST) is observed in Mundulla 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.

The perceived humidity level in Mundulla, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, staying within 1% of 1% throughout.

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 Mundulla experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 6.2 months, from September 10 to March 16, with average wind speeds of more than 5.6 miles per hour. The windiest day of the year is January 16, with an average hourly wind speed of 6.4 miles per hour.

The calmer time of year lasts for 5.8 months, from March 16 to September 10. The calmest day of the year is May 20, with an average hourly wind speed of 4.9 miles per hour.

The predominant average hourly wind direction in Mundulla varies throughout the year.

The wind is most often from the west for 2.0 weeks, from April 29 to May 13 and for 3.1 months, from July 24 to October 26, with a peak percentage of 42% on September 30.

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 extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.5 months, from November 6 to February 20, with an average daily incident shortwave energy per square meter above 7.1 kWh. The brightest day of the year is January 4, with an average of 8.4 kWh.

This report illustrates the typical weather in Mundulla, 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 is only a single weather station, Mount Gambier Aerodrome, in our network suitable to be used as a proxy for the historical temperature and dew point records of Mundulla.

At a distance of 152 kilometers from Mundulla, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .

The weight assigned to the MERRA-2 value depends on the distance from Mundulla to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 4%, making the weight assigned to the weather station 96%.

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.
