We all know that these two months are the best for sailing around Perth, and the WA coast during these months is probably the best in Australia for any two month period of the year, but how good is it? Thanks to the wealth of information in the GPS Team Challenge site, I deduced this;
In December, sessions were logged by at least one of the Greater Perth (incl. Mandurah) teams on 24 of a possible 31 days. The peak speeds on these 24 days were;
20-25 knots 3 times
25-30 knots 6 times
30-35 knots 8 times
35-40 knots 5 times
40+ 2 times
In January the story was similar; 25 days of sailing with the following break up;
20 -25 knots 1 times
25 -30 knots 8 times
30 -35 knots 11 times
35 -40 knots 3 times
40+ knots 2 times
I thought it was probably a pretty average year for wind - seen better, seen worse and hoping for plenty more in the next month or so.
Anyway, if we leave out the days where top speed was under 25 knots, that still means that someone around Perth exceeded 25 knots on 72.5% of the days, and that is just over 5 days per week! Not bad - aren't we lucky!
Yeah, I think we can expect the forum topics to degenerate if these bloody Easterlies keep up!
Interesting stuff though - is there a better city in the world than Perth for windsurfing? Not suggesting there isn't, but none come to mind. Maui is definitely much windier but a city it aint.
I think I'll stick this on GPS-Speedsurfing as well - extend the jealousy to Europe, not just just the Eastern Seaboard of Australia!
...and here's November for good measure; 21 days of sailing out of 30 = 70%, but speeds (winds) were a little slower.
20-25 knots 5 times
25-30 4 times
30-35 6 times
35-40 6 times
The number of sailable days could be even higher, if lots of people (like me) go wavesailing if there's swell and wind... no GPS and no record on the challenge site then 
I'll throw in poor old October too - surprisingly not too bad- 21 sailing days out 31.
20 - 25 knots 4 times
25 - 30 knots 6 times
30 - 35 knots 7 times
35 - 40 knots 3 times
