Cold weather down under: Lack of CO2-induced warmth results in waves of only more than 18 meters; wind gusts of only 178 kilometers per hour

The weather bureau has revealed a series of cold fronts caused Tasmania's extreme weather conditions last month, bringing record low temperatures and huge swells.

The extreme conditions reached their peak on the 23rd, when Liaweenee in the Central Highlands recorded minus 11.2 degrees overnight, the second coldest July temperature on record.

The cold fronts also whipped up massive swells that damaged Port Arthur and other sections of Tasmania's south-east coast.

In the north, the Cape Sorell wave rider buoy recorded its largest ever swell of more than 18 metres.

Ian Barnes-Keoghan from the Bureau of Meteorology says the cold fronts also caused powerful wind gusts, especially in the west and south.

"178 kilometre an hour gusts recorded on Mt Wellington, 176 down on Maatsuyker Island. That brought damaging surf which caused a lot of problems on the Tasman Peninsula, coastal erosion," he said.
