Rainfall

Rainfall during winter 2012 was below to very much below average throughout much of WA, and a few sites in the Great Southern observed their lowest winter rainfall in over 100 years of record, with the previous record being winter 2010. This low rainfall was in stark contrast to the above average rainfall reported in the nearby South and Southeast Coastal districts, mainly due to heavy rainfall in early June, and the fact that two sites in the South Coastal district reported their highest winter rainfall on record. Averaged across WA as a whole, winter rainfall was the 7th driest on record, whilst the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay) ranked as the 6th driest for winter 2012 (comparable records commenced in 1900) mainly due to the region registering its driest July on record. For the Southwest Land Division (SWLD) as a whole, rainfall in winter 2012 ranked as the 9th driest on record.

Significant rainfall events during winter 2012:

• June 2012 saw frequent rainfall in western and southern parts of the SWLD, with some sites recording rainfall on over 20 days in the month. A series of low pressure systems and cold fronts brought a number of significant weather events to the SWLD, which not only brought moderate to heavy rainfall, but also damaging winds and significant storm surges during the first half of the month, particularly between the 7th and 13th. Please refer to the Special Climate Statement 40 for detailed information on these events. The second half of June saw mainly light to moderate rainfall events in the SWLD, with the passage of several more moderate cold fronts.
• A slow moving trough and low pressure system moved over the SWLD at the end of May and the start of June bringing moderate to heavy rainfall and thunderstorms to southern and eastern parts of the SWLD and adjacent Goldfields. A number of locations in the Southwest and South Coastal districts registered daily rainfall totals over 80 mm during the first two days of June, and broke their winter daily rainfall record. Peppermint Grove in the South Coastal observed 174.2 mm on the 1st, which is a June record in its 106 years of record and the second highest daily total for any month for the site behind the 196.9 mm on 6 May 1921. It was also the 2nd highest daily rainfall total for June for the SWLD. Warner Glen in the Southwest district recorded a total of 106.4 mm on the 1st, which was its wettest day in its 63 years of record. Tamaru in the South Coastal received a daily total of 116.2 mm on the 2nd, which was the highest daily total for any month in its 47 years of record. Several sites in the South Coastal district recorded their highest June monthly total rainfall due to a combination of this event and above average rainfall for the remainder of the month.
• A low off the WA west coast on 6 June brought extensive cloud to much of the state resulting in areas of rain over much of western WA. Heavy falls were observed in the Pilbara and Central West, with totals over 50 mm reported near Roebourne, whilst highest June daily falls in 10 years were reported at some Pilbara sites as a result of the unseasonal rainfall.
• A rapidly deepening tropical low off the northwest coast moved near the west coast during the morning and crossed the Southwest district during the afternoon on 10 June. The system brought very windy conditions to the Lower West, Southwest, South Coastal, and Great Southern districts. The highest recorded wind gust during the event was 146 km/h at Cape Naturaliste, which is the strongest wind gust observed at the site in almost 10 years of record, and the 4th strongest wind gust on record in Western Australia in the May to August period. Widespread property damage was reported in western parts of the SWLD with a significant number of trees downed, and 800 power lines southwest of a line from Geraldton to Ravensthorpe damaged. More than 170,000 homes lost power and it took several days for power to be restored to all residents in the region. A significant storm surge with minor coastal inundation was reported along the SWLD west coast. Some moderate to heavy falls were observed in the west Pilbara, west Gascoyne, and western parts of the SWLD during the event and a few locations in the northern Central West recorded their wettest winter day on record as a result.
• Most of WA, apart from the Kimberley, experienced a wet day on 11 June as a cold front moved through the SWLD and a cloudband moved across northwest and central parts of the state. Moderate to heavy falls were mainly confined to southern parts of the SWLD, whilst west coast parts of the division endured more severe winds and a storm surge event.
• A rapidly developing cold front and deep low pressure system moved through the SWLD during the afternoon and evening of 12 June, and through central and eastern parts of southern WA on the 13th. Widespread rainfall was recorded through the SWLD, with heavy falls in the 40 mm to 60 mm range in the Southwest and Lower West districts. Thunderstorms, moderate to heavy rainfall, and severe wind gusts were reported in the SWLD, particularly in the Southwest and neighbouring districts, as further roof damage was reported to buildings, trees were uprooted, and additional power lines were downed. Another storm surge occurred although it was weaker than previous recent events.
• Individual rainfall events over southern WA during July were mainly confined to cold fronts moving through the region on the 6th to 8th, 10th to 12th, 16th and 17th, and 23rd and 24th, though falls were generally modest. Otherwise, strong ridging over southern WA resulted in generally clear conditions across much of the state for much of the month, and thus WA recorded its 3rd driest July, and a significant number of stations in the SWLD recorded their driest July in more than 100 years of rainfall recording.
• A strong cold front moved over the southwest corner of WA early on 31 July, bringing widespread rainfall to the SWLD and some heavy falls to the Central West with several stations observing their wettest August daily rainfall total in the 24 hours to 9am on the 1st. Following this front a generally westerly flow and a series of cold fronts over southern WA during the first week of August 2012 brought consistent rainfall to the region, although daily totals after the 1st were generally only light to moderate and August totals very below average across most of WA.

Maximum temperature

Mean daily maximum temperatures during winter 2012 were above to very much above average throughout most of WA, apart from in the southeast Kimberley which saw below average daytime maxima.. Areas of highest on record were evident in the west Pilbara and far norhtwest Gascoyne where temperatures were up to 3 °C above normal. Learmonth recorded its warmest winter in 37 years of record with a mena maximum of 26.6 °C, whilst Emu Creek Station recorded its equal warmest winter.

When averaged across the state, the mean maximum temperature for winter 2012 was above average, whilst the Lower Southwest also recorded an above average winter.

A high moving south of WA in mid-August resulted warm to hot conditions through northwest and central parts of WA from the 16th through to the 21st, with unseasonally hot days observed in the west Pilbara and Gascoyne on the 18th. Onslow Airport observed its warmest winter temperature in 48 years of record on the 18th, with a maximum of 35.2 °C. Hot conditions re-established over northern WA late in the month and Telfer Aerodrome recorded a maximum temperatue of 36.0 °C on the 28th, its equal highest winter temperature in 39 years of record.

Minimum temperature

Minimum temperatures were below to very much below average during winter 2012 in most of eastern and northern WA, with temperatures up to 4 °C below normal in the northeast Kimberley. Western and central WA saw mostly near average overnight temperatures, with areas of above average mean minima in the west Pilbara, west Gascoyne, and northern SWLD, and areas below average in the central and eastern SWLD, and in the Goldfields.

When averaged across the state, the mean minimum temperature for WA for winter 2012 was very much below average, and ranked as the 7th lowest since comparable records commenced in 1950, whilst the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay) was near average.

Cloudy skies and northerly winds in the western parts of the state in the second week of June brought unseasonally warm nights on the 10th and 11th. Emu Creek Station in the west Pilbara recorded a minimum of 22.2 °C on the 10th, its warmest winter night in 41 years of recording, and Kalbarri recorded a minimum of 19.4 °C on the 11th, its warmest winter night in 39 years of recording.
