Water temps.
San Diego is 63 degrees
Caribbean is around 78-82 degrees
the op sez triptime is
'late summer.'
uncle sam (noaa) tells us that water temps around San Diego then can be reasonably expected to be 'warm,' ie 70+.
ergo
fail, in addition to selective nitpicking.
the other two at that time?
Puerto Rico -83.
Hawaii - 80.
of course, sum of us have already been in the water this year, in Maine.
katey used to hit the surf over in Saybrook starting in April. i guess that we have a different sense of what 'cold water' means.

and since it's also low to mid 70s water temp around here at that time, i would suggest to rent a home with white sand beach, and mebbe a pool, not too far from the casinos so you could have a quick trip to a fun place when the op needs to 'get out of the house' for a bit. here's how the logistics on that move could look:
walk out of house. turn key on the yugo. bust down the highway for a bit, park car in new drive. already in 'bathing suit,' exit car, walk down to surf, jump in.
no trains, planes, car service, papers, lugging, standing around, wondering if that airport terminal hotdog is really safe to eat, no cattle calls or seatback kickers, no need for pocket cash to tip people for whatever, no language issues, .... wait, whut? why can't that guy stop sneezing?
none of it. i think they call it a 'vacation,' a term originating in America by the nyc doctor who first used it to describe the folks coming to his Adirondack health getaway from the city, as they 'vacated' it in pursuit of fresh air for the lung illness of that time.
bring sum cowboy ribeyes, leave the immodium and pepto at home.
