When can I catch kings off the beach

I didnt realize I could catch kings off the beach until today. what gneral time year can that be done so I can start looking on the forum for updates. I have a small boat 198 DLV and feel more comfortable fishing near shore or off the beach close in. Can anyone give me more information? thanks.

whan the water temps reach 68 degs.
