MONTHLY CLIMATE SUMMARY - VICTORIA
August 2005 was a month of contrasts.
During a cold outbreak on the 10th, snow fell at many sea level localities (for example, snow covered the beach near Inverloch during that day).
In contrast, during a warm and windy spell at the end of the month (Melbourne Airport registered a gust of 102 km/hr on the 30th), a number of centres registered their highest August minimum temperature on record (for example, Mildura Airport, with 18.8 deg C during the night of 29th/30th). Mt Hotham recorded a Victorian wind gust record of 198 km/hr, whilst Mildura Airport equalled their August wind gust record (91 km/hr) during the evening of the 30th.
Overall, night-time temperatures during August averaged close to normal at most places, whilst daytime temperatures were mostly about 1 deg C above normal. Over winter as a whole, both minimum and maximum temperatures were about 1 deg C above normal in most districts.
August rainfall totals were close to normal. Over winter as a whole, rainfall was somewhat above normal in the Northeast and in East Gippsland, somewhat below normal in Central Victoria and in West Gippsland, and near to normal elsewhere.
In Melbourne, the average minimum temperature for the month was 8.2 deg C (normal 7.4 deg C), whilst the average maximum temperature was 16.3 deg C (normal 15.1 deg C). 60.4 mm of rain fell (normal 57.4 mm). Over winter as a whole, it was warmer than usual (mean minimum: 8.4 deg C, normal: 7.1 deg C; mean maximum: 15.9 deg C, normal: 14.3 deg C), and rainfall was close to average (141.4 mm, normal: 148.7 mm).
Westerlies characterised the month's weather maps, with the rapid passage of fronts, except for a brief period later in August, when a strong high established itself over southeastern Australia.
