Thanks for the link, Stodelle.
The shark link was interesting, especially the graph of shark attacks vs. people in the water by month:http://www.state.hi.us/dlnr/dar/sharks/ ... eople.html
It shows Oct-Dec and March-April are the most dangerous times: largest number of attacks when there are the fewest people in the water. Maybe months to avoid solo diving and keep an extra lookout. What do people think?
Also was nice to see all the known shark attacks described since 1990 or so. Make me nervous if I was a surfer...
I would also look at sea surface temperature and see if those are the periods of the coolest water temperatures (I doubt it, but it would be worth a look). You also have the Kohola (humpback whale) migrating down in Oct/Nov at the earliest and leaving around March-April (that could be interesting). Jan-Feb is too cold, less people at the beach (plus big waves in the North).
Good stuff though.
