Sydney in March 2017: A wet March with record-warm nights

Rainfall was well above average in Sydney during March, with Observatory Hill recording its wettest March since 1975. March was notable for the persistence of rain, with the most rain days since 1990 and the least sunshine since at least 1978. Overnight temperatures were the warmest on record for March across the city, with very warm nights throughout the month. In comparison, daytime temperatures were close to average, with only one day reaching 30 °C.

Persistent rain brings wettest March since 1975

  • While no day reached 50 mm at Observatory Hill, falls above 50 mm were recorded at some stations on the 4th, 15th, 18th, 22nd, or 31st, with some short-record stations recording their wettest March day on record and flash flooding in parts of the city on the 14th and 22nd
  • The persistent rain was associated with cloudy conditions, with an average of 4.5 hours of bright sunshine recorded at Sydney Airport, the least-sunny March since 1989 (the average is 6.9 hours)

Record-warm nights across the city

  • Overnight temperatures were more than 2 °C above average across the city during March, the warmest on record for every Sydney station

Most values are the precipitation in the 24 hours to 9 am on the day indicated. Days marked with → are part of a longer accumulation, which is shown on the final day.
Values over 100 mm have been rounded to the nearest whole millimetre.
Days marked with - have a rainfall report of zero; days left blank have no rainfall report (which often indicates no rain fell).

Notes

The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in 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 statement has been prepared based on information available at 8 am on Monday 3 April 2017. 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.
