The lowest chance of overcast or mostly cloudy conditions is 20% on March 9. The clearest day of the fall is March 9, with clear, mostly clear, or partly cloudy conditions 80% of the time. For reference, on November 21, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 32%, while on August 12, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 85%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Broken Hill, the chance of a wet day over the course of the fall is gradually increasing, starting the season at 7% and ending it at 9%. For reference, the year's highest daily chance of a wet day is 10% on January 31, and its lowest chance is 5% on March 26. RainfallTo show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during the fall in Broken Hill is essentially constant, remaining about 0.7 inches throughout, and rarely exceeding 3.1 inches. SunOver the course of the fall in Broken Hill, the length of the day is very rapidly decreasing. From the start to the end of the season, the length of the day decreases by 2 hours, 33 minutes, implying an average daily decrease of 1 minute, 41 seconds, and weekly decrease of 11 minutes, 47 seconds. The shortest day of the fall is May 31, with 10 hours, 12 minutes of daylight and the longest day is March 1, with 12 hours, 45 minutes of daylight. The latest sunrise of the fall in Broken Hill is 7:19 AM on April 6 and the earliest sunrise is 59 minutes earlier at 6:19 AM on April 7. The latest sunset is 7:38 PM on March 1 and the earliest sunset is 2 hours, 31 minutes earlier at 5:07 PM on May 31. Daylight saving time (DST) ends at 2:00 AM on April 7, 2024, shifting sunrise and sunset to be an hour earlier. For reference, on December 21, the longest day of the year, the Sun rises at 5:54 AM and sets 14 hours, 15 minutes later, at 8:09 PM, while on June 20, the shortest day of the year, it rises at 7:04 AM and sets 10 hours, 3 minutes later, at 5:07 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 the fall of 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 Broken Hill is gradually decreasing during the fall, falling from 2% to 0% over the course of the season. For reference, on January 24, the muggiest day of the year, there are muggy conditions 4% of the time, while on May 8, the least muggy day of the year, there are muggy conditions 0% 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 Broken Hill is decreasing during the fall, decreasing from 10.5 miles per hour to 8.8 miles per hour over the course of the season. For reference, on December 13, the windiest day of the year, the daily average wind speed is 11.5 miles per hour, while on May 19, the calmest day of the year, the daily average wind speed is 8.6 miles per hour. The lowest daily average wind speed during the fall is 8.6 miles per hour on May 19. The hourly average wind direction in Broken Hill throughout the fall is predominantly from the south, with a peak proportion of 52% on March 23. 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). The growing season in Broken Hill typically lasts for 11 months (345 days), from around July 22 to around July 3, rarely starting after August 21, or ending before June 10. The fall in Broken Hill is very likely fully within the growing season, with the chance that a given day is in the growing season gradually decreasing from 100% to 96% over the course of the season. 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 Broken Hill are very rapidly increasing during the fall, increasing by 1,264°F, from 3,964°F to 5,227°F, over the course of the season. 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 Broken Hill is very rapidly decreasing during the fall, falling by 3.9 kWh, from 7.1 kWh to 3.1 kWh, over the course of the season.

Data SourcesThis report illustrates the typical weather in Broken Hill, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Broken Hill is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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. The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Broken Hill, according to the International Standard Atmosphere . All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , by Jean Meeus. 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.

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.
