The episode as NWS MTR wrote it up.
Two children were playing in the water at Ocean Beach and were swept out in a rip current. Their parents went in after them and were also swept out to sea in the same rip current. All four were rescued by a lifeguard and some surfers. Two additional children were also caught in a rip current that same day at Ocean Beach and needed to be rescued.

Area Forecast Discussion
National Weather Service San Francisco Bay Area
1017 AM PDT Wed Jun 3 2020
.SYNOPSIS...Hot conditions are likely once again across the
interior today with coastal areas also well above seasonal
averages. A cooling trend will begin, most notably near the coast,
as onshore flow increases on Thursday. Much cooler and
potentially unsettled conditions are expected Friday and into the
upcoming weekend.
&&
.DISCUSSION...as of 08:25 AM PDT Wednesday...The biggest short
term impact continues to be focused around heat and heat related
illness potential. Satellite shows mostly sunny skies across the
Bay Area and Central Coast early this morning. Sunny skies, high
pressure and a warm airmass will lead to another hot day around
the region. Latest 24 hour trend indicates many spots around the
region are running 5-10 degrees warmer than yesterday morning - or
in the 60s and 70s. All that being said, a Heat Advisory remains
in effect through this evening away from the coast. The coast will
still be warm, but lack offshore flow and lingering onshore flow
will keep temperatures in check.
Did a forecast update early this morning to include a slight
chance for thunderstorms for southern Monterey/San Benito
counties. Satellite imagery does show moisture/cumulus clouds to
the SE of the region tracking northward. Daytime heating and
advancing moisture will be enough for a slight chance of
thunderstorms late this afternoon/early this evening. Models do
generate a few showers with increasing instability parameters
(CAPE/-LIs/Lapse Rates). This update also aligns with the Day 1
Outlook for general thunder mention from SPC, which has southern
areas mentioned.
&&
.PREV DISCUSSION...as of 02:38 AM PDT Wednesday...Clear sky conditions
prevail over the region this morning as temperatures remain mild,
generally in the lower 60s at the coast to lower 70s inland
(mid/upper 70s in the hills/ridges). This is as high pressure
aloft has allowed for 850mb temperatures to warm to above 20 deg F
with offshore flow. At the surface, light winds persist with weak
onshore flow likely to hold temperatures down slightly near the
coast. Meanwhile, interior locations are once again forecast to
warm well into the 90s and up to around 102 deg F in the warmest
interior valleys. Thus, a Heat Advisory remains in effect from 10
AM to 9 PM today across the interior. While coastal locations will
be cooler, still expecting values around 10 to 15 deg above
average just a few miles inland from the Pacific.
Cooling is likely to occur on Thursday as onshore flow increases and
spreads inland. This should allow for 5 to 10 deg of cooling for
much of the region reducing heat related risks. That said, interior
locations will still be warm into the low to mid 90s with isolated
spots such as Pinnacles National Park reaching into the upper 90s.
Overnight temperatures will also cool, especially in the lower
elevations as marine air beings to spread inland.
This week's heat wave will come to an abrupt end on Friday as a
mid/upper level cut-off low currently off of the southern California
coast ejects inland. This too will be in advance of a larger scale
pattern shift as a deepening mid/upper level trough digs southward
out of the Gulf of Alaska and into the Pacific Northwest this
weekend. In response, temperatures fall to as much as 10 deg below
seasonal averages across the interior by Saturday and Sunday. This
system will also produce the possibility of a few showers over the
region from late Friday into Saturday with lingering precipitation
chances over northern California through the weekend. However,
widespread rainfall is unlikely at this time with most locations
likely to remain dry. Temperatures then look to rebound and begin to
warm early next week as the aforementioned mid/upper level trough
ejects to the east and high pressure builds over the eastern Pacific.
&&
.AVIATION...As of 10:17 AM PDT Wednesday...For 18Z TAFs. VFR
conditions are forecast to prevail through the TAF period with a
few passing high clouds. Could see some slightly reduced
visibilities around sunrise tomorrow morning associated with haze
near Monterey, similar to this morning. Light winds this morning
turning onshore this afternoon around 10-15 kt.
Vicinity of KSFO...VFR with just a few passing high clouds. Light
easterly winds this morning will reverse and become west this
afternoon around 10-15 kt.
SFO Bridge Approach...Similar to KSFO.
Monterey Bay Terminals...VFR with high clouds and generally light
winds. Could see some slightly reduced visibilities around
sunrise tomorrow morning associated with haze near Monterey,
similar to this morning.

.MARINE...as of 8:54 AM PDT Wednesday...Gusty northwest winds
will persist over the northern waters through the end of the work
week as high pressure remains over the eastern Pacific. These
winds will generate steep fresh swell resulting in hazardous seas
conditions for smaller vessels. Generally light to locally
moderate winds are expected elsewhere across the waters. Mixed
seas will continue with a shorter period northwest swell and a
longer period southerly swell.
