Windy at first with Southern Ocean fronts rumbling through. Bands of rain with these fronts followed by a cluster of showers in cooler air. A snowline of 1000m into the 2nd, with 15cm report at 1200m.  Clearing as high pressure approached from the west,  then hot and sunny between the 13-15th with high pressure moving to the east. The 16th brought a cool but dry change with heavy cloud and a southerly wind, then new high pressure moved to the south of Tasmania circulating onshore easterly winds up to the 23rd, as low pressure occupied eastern Australia. These winds off the sea brought low cloud, with low pressure moving south at times, bringing periods of showers but longer rain on the 22nd. A slack westerly wind change from the 24th-31st with mostly dry fronts, followed by high pressure ridging in from the south east. These onshore winds brought murky cool days even though dry - 31st most notable for murkiness. The wettest day was 34mm on 22nd.
