This autumnal weather is so much more moderate compared to the summer.
Less confidence in making a longer sail. Imagine further North is still more summery pattern with seabreezes.
For example, today I was planning to go from Halls head to Bunbury (about 47nm). The morning dawned with maybe 8 kknots easterlies. The better option now is to sail the shorter sail back up to Pengo for some 10:30am high tide offshore swell conditions at the surf spot.
Perhaps if thing slook OK, for sailing on to Rottnest then I could get some golfing in and wait for this next low system to come in closer and squeeze the preesure gradient up a feew2 degrees.
