An offshore wind will flatten out the seas, but it will also blow you away from the land should you get in trouble. I prefer a light offshore. And it's the swell that kicks the sand up and wrecks the viz, not the wind. If you're diving the southern end of Philip Island then Sunday would be the pick of the days with northerly winds forecast - just be careful not to stray too far from the shoreline, and keep enough enrgy to kick back in against the wind. Saturday will also be nice with the light easterly early, but the seabreeze (southerly) will jack the swell up later.
If I were you I'd try and spear very early Sunday, 11-5 are convenient hours for spearing, but you'll do better at dawn <img src='http://www.squidfish.net/forums/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt=':lol' />
