Western Australia in March 2019: a record hot start to autumn
It was a record hot start to autumn for Western Australia, immediately after the State had experienced a very hot summer. The statewide mean temperature (average of maximum and minimum temperature) was the highest on record, and exceeded previous March record by a large margin. Daytime and overnight temperatures were warmer than normal for most of the State apart from some coastal areas. For WA as a whole, the mean minimum temperature was the highest on record for March and mean maximum temperature was the second-highest. The statewide March rainfall was below average, though above average rainfall was observed in parts of the Pilbara coast and adjacent inland due to severe tropical cyclone Veronica late in the month, and pockets in the State's southwest quadrant from a cloudband and thunderstorms.
Wet in parts of the Pilbara coast, dry in the Kimberley
- March rainfall was 36% below average for WA
- The north and east Kimberley saw the dry 'wet season' continued with March rainfall totals mostly 20 to 50% of March average
- Severe tropical cyclone Veronica produced rainfall, which were five to seven times of March average, along the Pilbara coast and adjacent inland between Port Headland and Karratha; a number of sites had their wettest March on record or wettest March since 1988
- Port Hedland Airport and Carlindie recorded a daily rainfall 179.4 mm on the 24th and 176.0 mm on the 26th respectively, which was their new March record
- Moderated falls on the 7th and 8th from a cloudband, and on the 20th from thunderstorms, resulted in a number of sites in the South Coastal district having their wettest March for over 2 decades; a daily rainfall of 74 mm on the 20th at Narrikup West was it wettest March day in 23 years of record
- Areas along the west coast to the north of and around Perth, and the State's southern coast east of Esperance mostly recorded less than 10 mm monthly rainfall totals; Karara in the eastern Central West district had its driest March since 1997
Hot days and very warm nights for most WA
- Mean temperature (average of maximum and minimum temperature) was 2.37 °C above average, which was the highest on record and exceeded previous record (+2.05 °C in March 1980) by a large margin
- The mean maximum temperature was 2.65 °C above average for WA, which was the second-highest on record and just fell short of the record (+2.70 °C in March 1980)
- The mean minimum temperature was 2.09 °C above average for WA, which was the highest on record and exceeded previous record (+1.72 °C in March 2016) by a large margin
- The southeast of the State sweated through the last day of summer and the first day of autumn; Eucla set new records for warmest March night and hottest March day on the 1st, while Forrest broke its highest Mach temperature record
- Extreme heat was sustained over a broad area from the Pilbara, Gascoyne to the Southern Interior between the 9th and 11th, with temperatures in many sites reaching mid-to-high 40s and set new March records
- Roebourne Airport recorded a national highest March temperature of 48.1 °C on the 10th, previous record was 47.8 °C on 6 March 2007 at Carnarvon Airport
- Mean maximum temperatures were over 39 °C in inland northern and eastern WA, with a number of sites had their hottest March on record
- Mean maximum temperatures were 33-34 °C in the Central Wheat Belt and southern Goldfield, with a number of sites had their warmest March for over 2 decades
- Nights were very warm with mean minimum temperatures of 25 °C to 28 °C in the Pilbara and the northwest offshore islands, some sites had their warmest March nights on record
Severe tropical cyclones Savannah and Veronica
- A tropical low was identified about 970 kilometers east of Christmas Island on the 8th, and later became Tropical Cyclone Savannah about 110 kilometers west of the Cocos (Keeling) Islands on the 14th. Strong to gale force winds were experienced on the islands. Vegetation damage and minor property damage were reported. Savannah tracked southwest and intensified to be a severe cyclone (category 4) on the 17th.
- A tropical low developed to Tropical Cyclone Veronica to the northwest of Broome in early morning on the 20th. Veronica intensified rapidly to become a severe cyclone (category 4) on the 21st, then tracked southerly towards the Pilbara coast and was located only about 50 kilometers north of the coastline to the west of Port Hedland as a category 3 system on the 24th. Veronica remained almost motionless for the next 24 hours and the coastal and adjacent inland areas between Port Hedland and Karratha had subjected to a prolong period of destructive winds and very heavy rainfall. Veronica weakened to a category 2 system on the 25th before moving westwards and finally downgraded to a tropical low to the west of Karratha on the 26th and passed the Exmouth on the27th. Significant flooding occurred and many homes were evacuated in the Port Hedland area. Many streams and waterways in the De Grey catchment reached minor flood level.

Notes
The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in Western Australia 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 10 am on Monday 1 April 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.
