Katmai went back in to the water on schedule just before Christmas and boy were we glad. The Christmas season brought really unusual and interesting weather to much of Australia. We were glad to observe the weather from the comfort of our boat, in the harbor.
There were two large storm systems influenced the weather in Fremantle, even though they were relatively distant.
37.5 knots of wind in the harbor was not unusual during Christmas week 2016 |
The Fremantle Sailing Club Cruising section members are planning on sailing south to Quindalup for the holidays. While some boats have departed we are waiting for more favorable winds.
The following three synoptic charts from the Australia Government weather service really show the story of the unusual weather we have experienced.


The most amazing thing happened next. Within 18 hours, a major Low Pressure system (storm) formed in the Australian bight. As the next High pressure system (the 1022 on the Chart) tried to move in to the bight, it compressed against the big Low. This compression is expressed as the isobar lines on the chart are close together, bringing more wind to the west coast of Australia.
It is three days later as I type this and things are improving weather-wise. The Low in the bight has moved considerably to the east and the more normal pattern of high pressure systems moving though has resumed. We plan on heading south tomorrow and hope for some nice easterly winds to ease us south. The strong southerlies of the last week would have been right 'on the nose'. We will be off for just a few days for local sailing/fishing and socializing with friends.
