The most outstanding weather event during the last few days was record high temperatures for July at several centres across the Nation. It first started in the Pilbara region of WA.

Roebourne , recorded 35.0 last Thursday 27th July, just beating the previous record of 34.8 in July of 2010. Karratha recorded 34.0 and this was over a degree higher than the July 2000 record.

On the extreme SE of WA , Eucla recorded 30.3 and this broke the previous July record of 29.3 set 100 years ago in 1917 .

There was a lot of rain in our region from September 1917 through to May 1918. In SA , Coober Pedy, Oodnadatta, Woomera and Loxton all recorded their highest July temperatures since 1975, 1964, 1975 and 1975 respectively, the readings being 30.4, 31.2, 28.2 and 27.3.

The unseasonable July warmth reached Mildura on the Saturday when the temperature soared to 27.1, a new July record at the Airport in 70 years of records.

The old Post office records going back to 1885 show there was a higher reading of 29.8 in July 1892. In NSW Bourke recorded 29.2 on the Sunday and this broke the previous July record of 28.9 in both July of 1926 and 1990.

Sydney also recorded it's hottest ever July day with 26.5. In Outback QLD St. George recorded 28.7 on the Sunday 30th July, it's hottest July day there since 1942.

The unseasonable warm weather bypassed our regions last weekend. Maximum temperatures were all much lower by more than 10 degrees in NE Victoria than those places in SA and at Bourke.

Nevertheless these record July temperatures across the Nation are a prelude to wetter than average conditions in our regions for the rest of this year, continuing into early next year.

As many of the places listed above previously had record July temperatures in 1975, there was excessive rains from August to February 1976 at most places in our regions.
