Greater Sydney in June 2019: typical start to winter

It has been a fairly typical start to winter for Greater Sydney. Despite a few wet rain days during the months, rainfall was close to average for most locations. Daytime and overnight temperatures were also close to average.

A few heavy rain days

  • Rainfall totals during June were close to average for most locations across Greater Sydney, while some coastal sites recorded above average falls
  • Total rainfall for Sydney (Observatory Hill) was 171.4 mm, which is 128% of the long-term average of 133.5 mm
  • Rain fell over 15 days at Sydney (Observatory Hill), compared to the average count of 13 rain days for the month
  • Moderate falls were reported on the 4th and 5th, as a complex area of low pressure produced thunderstorms and showers across Greater Sydney; a two day total exceeding 40 mm was reported at many sites
  • A surface trough about the central coast between the 16th and 18th again generated moderate falls across Greater Sydney; Randwick recorded a three day total of 108.8 mm
  • Onshore flow from the 24th saw more wet days for Greater Sydney; Wyong (Mount Elliot) recorded a daily total of 70.0 mm on the 24th
  • The first half of 2019, Sydney (Observatory Hill) recorded 560.6 mm, which was below the January to June average rainfall

Above average temperatures

  • Daytime temperatures were mostly within 0.5 ºC above average, except for Sydney (Observatory Hill) which was 1.5 ºC warmer than average
  • Warm days were generated between the 8th and 13th ahead of a cold front and a number of sites had their highest June temperature on record
  • Overnight minimum temperatures were close to average for most locations and within 0.5 ºC of average, except for Sydney Airport which was 1.2 ºC above average
  • Several cold nights away from the coast from 19th to the 23rd as a slow moving high pressure system in the Bight dragged cool air over Greater Sydney; Mount Boyce AWS had their equal coldest June temperature on record on the 21st
  • Sydney (Observatory Hill) has experienced its warmest January to June period on record, 25.0 ºC for mean maximum temperature (previous record 24.8 ºC in January to June 2016)

Sydney (Observatory Hill)

  • The mean daily maximum temperature for Sydney (Observatory Hill) was 18.5 °C, which is 1.5 °C above the long-term average of 17.0 °C. The warmest day was 23.3 °C on the 11th, and the coolest day was on the 4th when the temperature reached 14.1 °C

Thunderstorms and moderate falls

  • A complex low pressure system on the 4th, generated thunderstorms, big swells, damaging winds and heavy falls; a maximum wind gust of 119 km/h was recorded at Wattamolla and there were reports of damages to numerous yachts and boats
  • Low winds and cool, moist air generated thick fog across Sydney in the early hours of the 8th and delayed flights at Sydney Airport
  • Moderate to heavy falls on the around the 17th and 23rd caused localised flash flooding and Sydney (Observatory Hill) recorded 33.6 mm and 34.2 mm respectively

Notes

The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in Greater Sydney using the most timely and accurate information available on the date of publication; it will generally not be updated. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

This summary includes data from observing sites in or near the Greater Sydney “Greater Capital City Statistical Area” (GCCSA). The Australian Bureau of Statistics designed the GCCSAs to “include the population within the urban area of the city, as well as people who regularly socialise, shop or work within the city, and live in small towns and rural areas surrounding the city. It is important to note that GCCSAs do not define the built up edge of the city. They provide a stable definition for these cities and are designed for the output of a range of social and economic survey data.

This statement has been prepared based on information available at 11 am on Monday 1 July 2019. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

In some situations, some or all of the rainfall is in the form of hail or snow. In these cases the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.

Averages for individual sites are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.

Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
