RAINFALL
Most of the Geelong-Otways region – except to the north – received average to well above average rainfall for the month. The Bureau of Meteorology’s automatic weather station at Breakwater failed on 3 occasions during the month thereby missing approximately 20 mm of rain, thus affecting their published Geelong total. The rain for Breakwater as computed by Geelong Weather Services for May was 42.4 mm, just above the latest 30-year average 41.5.
Mt Sabine in the Otway Ranges at the head of the Barwon Catchment recorded the amazing 344 mm, well above its average. The storages are therefore at a stationary 57% of capacity, but an increase will be necessary over the winter months.
As far as autumn overall is concerned, this was a drier one than the most recent 30-year average. Geelong received 93 mm over the 3 months compared to the average 109 mm. This corresponds with a slowly drying trend in autumn over the last 30 years.
