Most areas surrounding Geelong had above average falls in January, owing mainly to several thunderstorms. However Geelong’s southern suburbs generally did not benefit from those and only ended up with around 30mm, a strange anomaly in the midst of higher falls. In spite of this, relative humidity remained very high on several non-rain days. There were 2 thunder days, and a severe thunderstorm occurred across the northern suburbs from Corio to Lara, moving across the bay to Curlewis on the 21st causing flash flooding and large marble-sized hail in a number of places. During this storm Belmont only received 1.5mm.
