Geelong received only around half to two thirds of its normal July rain, according to figures compiled by Geelong Weather Services. Geelong Airport received only 23.6 mm, just below half of the average, although some other suburbs (eg, Leopold) exceeded 35 mm. Disappointing falls of the same proportions were received in the Otways and the catchments are still at 32.5% of capacity, although this is higher than at the same time for the past two years.
Cooler than average by 0.2 degree C was the Geelong region’s July result, in spite of comments by some that southern Victoria would end up warmer than normal. Those generalised comments have seldom been correct for the Geelong region, as the figures from Geelong Airport AWS are actual raw data, not subject to any weighted area grids. The systems of grids used result in numbers about data, rather than the pure recorded data itself. As such, those types of generalisations are best avoided.
Neither is Geelong Airport AWS warming in July. The 19-year mean temperature linear trend (1992-2010) is statistically level and this is Geelong’s seventh coolest July in that time. Minimums have been decreasing fractionally (
Our average daily minimum was 5.5 C, exactly on average. The maximum daily average was 13.6 C, compared to the mean maximum 14.0 C. Highest maximum was 17.6 C on the 30th, and lowest was 10.1 C on the 28th. Highest overnight minimum was 9.3 C on the 11th and the lowest was 1.4 C on the 9th. There were 3 frosts.
There were 3 days of strong wind gusts over 60 kph, on the 10th, 13th and 14th. As testament to a slow-moving high pressure system over Victoria, there were 5 or 6 days of fog in the final week, including a persistent day-long fog on the 28th when the temperature only reached 10.1 C. There was 1 thunder-day on the 31st, but no storms. An unusual feature was the mammatus sky on the 10th, which unfortunately resulted in no rain.
