I agree, check with The Spot. Gary Bulla will have good info for fishing the salt. A bit of a drive north could get you onto some of the small costal streams of Big Sur, but they are small!
The San Ynez is over the hill from SB, but to be honest you really don’t hear much about it. There are sections that are tailwaters, and with this being a very dry year, I doubt there’s much of a release going on. Otherwise you may look into the small streams of Sespe Creek and Piru Creek. They’re both a bit of a drive east from SB in Ventura, Co. Our summer kicks in Aug-Oct, so it may be warm. Just make sure you’re not fishing streams where the water is too warm. Don’t want to increase the chance of mortality on our local native rainbows.
http://www.kernriverflyfishing.com/Kern River Fly Fishing has good info on the Kern and surrounding areas. You’d want to focus on the upper Kern, most likely in the 20mi section just above Lake Isabella. Just gotta watch out for tubers and rafts coming down the river.
Wherever you go, don’t leave any valuables in the car or give anyone a reason to break in, because they will.
