As a fun, we could initiate a fun game 40+.
Lest look at the weather forecast, spot and make a bet/ that this on that specific day/week could yield 40+ result anywhere in Australia.
example>
You could see perfect wind condition coming within next 7-3 days. Wind speeds, direction optimal for the spot to hit 40 at Sandy.You could post a bet on SB in advance, go there. make a sailing and prove that you are right....
I hope that many in Australia could jump into planes, trains or cars and help to you make a prediction to happen.
Unless obviously, 40+ is so unique that can not be so easily predicted, planned and executed.
but these people know exactly where to be in the time and space
