Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis 22 745 pm.
Overnight low clouds and patchy fog will continue west of the
mountains through early next week. Gusty onshore winds will
affect the mountains and antelope valley during this time. A
warming trend will raise temperatures to above normal for next
Short term (tue-fri) 22 804 pm.
a deep marine layer will remain in place over the area tonight
into Wednesday. As the upper closed over the region weakens
slightly tonight, the marine layer may be suppressed somewhat.
However, low clouds are expected to reform and push inland
overnight, with clouds over the coast and valleys all the way to
the western mountain slopes by Wednesday morning. Meanwhile, gusty
southwest winds will continue over the antelope valley, with
local gusts between 40 to 45 mph likely through late in the
evening. The other issue of note is elevated surf caused by a long
period south swell moving through the coastal waters. Surf up to
6 feet in height with occasional larger sets is expected through
Thursday, along with strong rip currents. The highest waves and
strongest currents will be on south facing beaches such as zuma
beach and port hueneme.
***from previous discussion***
a weak pop up ridge is expected over the region with 500 mb
heights rising to around 578 dm by Wednesday afternoon. A piece
of energy is expected to pinch off a trough of low pressure
currently positioned over the gulf of alaska and move into central
california Friday. Southwesterly flow aloft ahead of this feature
Thursday will support a modest increase in onshore flow with
lowering heights north of point conception. The increase in
onshore flow will likely maintain low clouds well into Thursday
afternoon for many coastal and valley areas. A 100+ knot jet
streak at 300 mb may help provide enough lift for drizzle or a few
light showers for coastal and valley areas north of point
conception (especially slo county). Have opted to leave out of the
forecast for now (tho did bump up pops) as there remains some
uncertainty of the eventual track of the system. Drizzle can't be
ruled out further south either, especially the climatologically
favored foothills and lower coastal slopes of eastern la county.
Temperatures will warm some, especially away from the marine layer
through Wednesday before gradually cooling through Friday, first
due to increasing onshore flow, then lowering 500 mb heights.
Locally gusty onshore winds will continue for the foothills of the
antelope valley each afternoon and early evening.
Long term (sat-tue) 22 227 pm.
Moderate confidence exists in the extended forecast mainly due to
uncertainty with the exact position and associated impacts of a
trough of low pressure expected to pass through the region.
The fastest model solutions have trended the core of the upper
level low closer to southwest california. Temperatures were
trended downward slightly (and could be lowered further by future
shifts) as a result of the low's proximity. This is unusually cold
feature for this time of year. Night to morning low clouds may
have trouble forming over the weekend as a result, especially
north of point conception. Will also keep an eye on the potential
for a few showers or thunderstorms over the mountains mainly
Saturday due to the low's proximity. Advisory level sundowner
winds are possible for western portions of the sba south coast
this weekend with gusty also possible in the la and vta mountains|
near the i-5 corridor.
The trough of low pressure is expected to exit into the four
corners by early next week. This will support increasing 500 mb
heights and weakening onshore flow, especially from the south. The
resulting lower marine layer and likely better clearing with
support a gradual warming trend with widespread 80s away from the
Aviation 23 0025z.
At 22z, there is a weak marine inversion at klax based at 4100
feet. The top of the inversion was at 5500 feet with a
temperature of 15 degrees celsius.
Overall, moderate confidence in coastal valley tafs and high
confidence in desert tafs. The inversion will lower some and burn
off time should occur earlier in the day. However, there is
reduced confidence in timing of both MVFR CIGS formation this
evening and dissipation Wednesday late morning-afternoon. Patchy
ifr CIGS are expected north of pt. Conception.
Klax... Moderate confidence in 00z taf. MVFR CIGS forecast to return
07z but may differ up to 2 hrs from TAF time. CIGS expected to
scatter out by 22z but timing is lower confidence. There is a 20%
chance of ifr CIGS occurring.
Kbur... Moderate confidence in 00z taf. MVFR CIGS forecast to
return 08z but may differ up to 2 hrs from TAF time. Cigs
expected to rise toVFR level by 17z but timing may be delayed up
to 2 hrs. 40% chance of ifr conditions overnight.
Marine 22 735 pm.
For the outer waters, high confidence in current forecast. Winds
and seas will remain below small craft advisory (sca) levels
through Thursday. By late Friday into Saturday, there is a 70%
chance of SCA level northwest winds. There will be a mixed swell
with shorter periods from the NW and long periods from the s.
For the inner waters, moderate to high confidence in current
forecast. For the waters north of point sal, winds and seas will
remain below SCA levels through Thursday then there is a 60%
chance of SCA level winds beginning late Friday into Saturday.
For the waters south of point conception, winds and seas will
remain below SCA levels through Thursday. Late Friday into
Saturday, there is a 50% chance of SCA level winds, especially
across western sections.
A long period southerly swell will continue to move through the
coastal waters through Thursday. Locally rough conditions may
occur at local harbor entrances, especially those with southerly
Lox watches warnings advisories
Ca... Beach hazards statement in effect through Thursday evening
for zones 40-41-87. (see laxcfwlox).
Hazard potential outlook (fri-tue)
Strong rip currents and elevated surf will linger at south-facing
beaches across los angeles and ventura counties through Thursday.
Advisory level sundowner winds are possible for western portions
of the sba south coast this weekend.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
