September 2015

RAINFALL

September was a most disappointing rainfall month, with Geelong only receiving around 60% of the 30-year average (32 mm compared to the average 50 mm).  Most of the region reported similar results.  Rain fell on only 12 days and the heaviest fall at Breakwater was 12.6 mm on the 15th.  Several promising days resulted in a disappointing fizzling out after early optimism.

The BoM predicts an average chance of median rainfall for the coming 3 months, which lends some optimism to farmers, gardeners and water managers.  At present the catchments are at 62% of capacity, not a good entry point into the spring-summer period.

TEMPERATURE

The month was a close to average one, with temperatures being about 0.2 degree C above the 30-year average.  The warmest day reached 28.3 C on the 14th and the coldest were 12.9 C and 12.7 C on the 22nd and 23rd respectively.  There was one frost (on the 1st) when the minimum dropped to 1.9 C.

OTHER FEATURES

The month was therefore a basically stable one – low rainfall, only one strong wind gust (61 kph on 6th) and one thunder day (14th) but no severe storms or other events of note.
