Chris,
Weather wise 10-15kn of SE with up to 1.2m of swell....that's it if you are in a boat under 6m.
Was on the phone with Crazy Pete Lowe last night...after looking at Google Earth he has a new appreciation of how far & exposed you are.
Tides need to be the biggest you can get either full or new moons, which can make it a Hawaiian Surf Movie on Sandy Cape Shoals and Spit Bombie on a big ebb tide into more than 1.2m of swell...1.5 tops unless you are in a larger vessel.
It's around 75NM run ONE WAY fro Urangan to Spit Bombie...though the trip is worth it...trust me!!
And you need to cross the Spit at some stage...means a bar crossing...during BIG TIDE WEEK, it means being there, at the bar with the tide still coming in...forget crossing in 15kn of SE with 1.5+ of swell down near the island...you would need to get up to the 13mile Gutter (13NM from Sandy Cape) to safetly cross...
Luke,
You are right...if you stay on the INSIDE of Fraser or leave from Urangan, you can still chase Trevor's down the Straits or go up to Platypus Bay & play with the Goldies, Mackerel, Tunas and little Billys that live their......time of year....now!!!!
Actually, the weather is the biggest determining factor for the area....Oct-Dec then April/May is most stable....though th BIG tides are Jan/Feb/March....whos going!!!
