| RAINFALL Below average rainfall in December did little to detract from the positive outcome of a much wetter winter-spring in 2010, and consequently, an above average year overall. Although December rains across much of Geelong were average, the official BoM gauge at Geelong Airport found itself on the outer once again with a disappointing 30 mm, having missed out on a couple of nearby thunderstorms. Otway
catchments received average totals and better, and the northern and Bellarine suburbs
again fared well. The catchments are now at 74% of capacity. For the year, virtually all of the region received between 100% and 120% of normal annual falls owing to the continuing La Nina situation. Urban Geelong recorded around 650 mm, compared to the 30-year average of 520 mm. It was Geelong's wettest year since 2001, when 714 mm fell at Geelong Airport and 657 mm across the suburbs. TEMPERATURE and OTHER
FEATURES Maximum
temperature was 30.7 C on the 3rd, and it was the only day over 30 degrees. The coldest
day (19th) only recorded 16.5 C. Lowest overnight temperature was 4.7 C on the 22nd and
warmest was 19.1 C on the 8th. Overall the
year has been just fractionally (0.2 C) warmer than the Airport long-term normal. Global
warming continues to evade the Geelong region, with no unambiguous signal discernible.
What has been discernible at Geelong Airport AWS since 1992 however, is the overall slight
temperature increases that are clearly related to urban encroachment, automobile emissions
due to a massive 70% road traffic increase and a bird manure-encrusted roof on the
Stevenson Screen which houses the sensitive temperature instruments. (Photo available on
request). There was
one severe storm, on the 3rd, when strong winds and a heavy thunderstorm struck the city
and northern suburbs depositing 20-30 mm of rain in less than an hour and creating chaotic
flash flooding. There were four very windy days with the top gust reaching 72 kph on the
11th. For a complete summary of the year's weather, please see the separate annual summary. |
