Record August heat in the Pilliga region of WA

By Peter Nelson on August 28, 2017

During last few days many places in the Pilliga region of WA experienced record high temperatures for August. Mandoora, 39.6, Karratha, 36.3, Onslow, 36.7, Telfer, 36.2, Roebourne, 36.5, and Marble Bar with 38.0 were all new record highs for August.

A few days later on Sunday, 27th August; Onslow set a new August high of 37.7. Marble Bar is well known for an all time record of 163 days in succession of maximum temperatures of over 100 F, 94 years ago. The 38 degrees ( 100.4 F ) last Friday 25th August was the town's first Fahrenheit 100 in 116 years of records.

The previous August high at Marble Bar was 37.2 on 27th August 1954. Other high August temperatures at Marble Bar were in 1928, 1935, 1940, 1977, and 1999. All these past episodes did lead to a warmer and drier September and early October than normally in our regions with not much rain except for light falls early and late September until late October, then a wetter November and summer season following.

The other towns in the Pilbara which had record high temperatures for August broke previous records which were set in 1954 and 1995 and both those years had warm dry September and early October and then it was very wet from mid October up to February the next year.

In the NT , both Darwin and Daly Waters had their hottest July in 135 years of records and this month will come close to being the hottest ever August. The record hottest July- August at both places were in 1906 and 1916.

Daly Waters has had it's warmest April to August this year since 1942. A very cold change swept across our region last Sunday 27th August which will result in heavy frosts on Monday morning and Tuesday morning.

However, the next low pressure trough currently passing over WA will bring warmer days by early September to our regions which will be welcome after the coldest August at many places since 2010.
