SUMMARY
Geelong experienced a massive unpredicted 100 mm of rainfall in June, after a 98 mm result in May, and all after the first four months produced less than 30 mm – the driest ever start to the year since records began in 1871. June was also warmer than average by around 0.4 degrees C.
This rainbow photo was taken at 8 am on 13th June looking westward, after 23 mm rain had fallen on Marshall.
TEMPERATURE
Warmer than normal by 0.4 C, Geelong’s top temperature was 19.1 C on the 9th, and on the coldest day (the 24th) the maximum only reached 10.5 C. Coldest overnight temperature fell to 0.3 C on the 24th as the first day of three consecutive frosts. Warmest overnight temperature was 11.9 C on the 29th.
RAINFALL
Well over 100 mm fell on Geelong’s southern suburbs in June, despite the BoM Breakwater AWS only registering 92 mm. Nonetheless it was enough to disrupt building programs and other outdoor events across town for the month, especially because 33 mm fell on the 3rd, 16 mm on the 13th and 12 mm on the 21st.
On the 2nd-3rd over 40 mm fell in some southern suburbs but only minor flooding occurred as a textbook situation arose when southeasterly winds from a low pressure system – unsheltered from the Otway Ranges – was directed over Geelong from Bass Strait.
Most of the rest of the region also received well above average falls.
OTHER FEATURES
There were two occasions when wind speeds gusted over 60 kmh on the 3rd and the 10th with a maximum of 70 kmh on the 3rd. There were no severe storms but at least two foggy days and three frosts.
An aircraft contrail is turned into a cirrus image just before sunset over Marshall on the 26th.
