Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

High pressure will gradually build over the area this weekend into
the first half of next week. This will result in a gradual
decrease in the extent of the stratus and fog. Additionally,
temperatures will be on the increase with excessive heat
conditions possible the first half of next week.
Short term (tdy-sat)
overall, 00z models in good synoptic agreement through the period.
At upper levels, weak low will linger over the area today then
ridge will begin to strengthen over the area Friday and Saturday.
Near the surface, weakening onshore flow will be the story.
Forecast-wise, main issues will be the extent of the marine layer
stratus and temperatures. Currently, marine inversion is based
around 2500 feet which is deep enough for stratus to push into the
santa clarita valley this morning which satellite currently shows.
The inversion is not too strong, so stratus should dissipate
rather well by late this morning and early afternoon. For tonight
and Friday, h5 heights rise a bit which should help squish the
inversion. However, still should be deep enough to have stratus
and fog push into the coastal valleys. However, by Saturday, the
marine inversion will be more shallow and stratus will be limited
to the coastal plain. Other than the marine layer stratus, there
may be some afternoon cumulus buildups this afternoon over the
mountains as some mid-level lingers.
As for temperatures, the combination of decreasing onshore
gradients, rising thicknesses h5 heights and warming boundary
layer will result in a warming trend through Saturday. The most
noticeable warming will occur across inland areas with some areas
around 100 degrees by Saturday.
Long term (sun-wed)
for the extended, 00z models continue to exhibit good synoptic
agreement. At upper levels, ridge centers itself over the great
basin with 592-594 dm heights over the area. Near the surface,
very weak onshore flow will prevail.
Forecast-wise, the above pattern is setting the stage for an
extended heat wave across the area. Afternoon temperatures will be
on a upward trend Sunday through Tuesday with inland areas
ranging between 100 and 110 degrees with even the coastal plain
ranging in the upper 80s and 90s. Overnight lows during this time
period will also be quite warm, ranging in the 70s to lower 80s
away from the beaches. So, excessive heat looks to be a
significant risk the first half of next week and an excessive
heat watch will likely need to be issued in the next day or two.
On Wednesday, temperature will cool a few degrees, but conditions
still look good for excessive heat criteria.
Otherwise, the above synoptic pattern will allow for the
possibility for some monsoonal moisture to move into the area. At
this time, the models keep any monsoonal precipitation south and
east of the area through the period. So, will continue with the
idea of some afternoon cloud buildups over the mountains each day,
but keeping the chances of precipitation at 10% or less. This
situation will need to be watched closely as the chances for
monsoonal precipitation could increase over the next few model
runs. Otherwise, marine layer stratus should be quite limited|
across the area, if not non-existent.

at 0530z, the marine inversion at klax was based at 1700 feet.
The top of the inversion was 2800 feet with a temperature of 20
Moderate confidence in category of low CIGS vsbys. There is a 30
percent chance of low MVFR CIGS vsbys at kbur, kvny, and koxr
after 09z. Low confidence in timing clearing low CIGS vsbys for
coastal TAF sites with moderate confidence for valley locations.
Low confidence in return of low CIGS vsbys with timing off by up
to 3 hours, locally more. There is a 20 percent chance of low
cigs vsbys prevailing through the period for coastal areas from
klgb to koxr including klax. There is nearly an equal chance of
low MVFR to ifr CIGS after 00z 25 for coastal and valley TAF sites
south of point conception.
Klax... Moderate confidence in TAF through 23z 24. Low confidence
in timing of the return of low CIGS vsbys (could be off by three
hours with nearly equal chance of low MVFR and ifr flight
category. There is a 20 percent chance that low CIGS vsbys prevail
through the TAF period.
Kbur... Moderate confidence in taf. There is a 30 percent chance
of low MVFR CIGS vsbys mainly after 09z.
Marine 24 220 am...
for the outer waters, moderate to high confidence in current
forecast. SCA winds will likely continue through late Saturday
with possible brief lulls each morning. Local gale gusts are
possible from the channel islands to point piedras blancas. There
is a chance of SCA winds continuing through to Monday.
For the inner waters, high confidence in current forecast. For
the waters north of point sal, northwest winds will increase with
sca level winds likely each afternoon and evening through late
Friday. For Saturday and Sunday, winds are expected to drop below
sca levels. For the waters south of point conception, winds and
seas will remain below SCA levels through Sunday.
Patchy dense fog this morning may more widespread across all
waters this weekend.
Lox watches warnings advisories
Pz... Small craft advisory in effect from 1 pm this afternoon to 3
am pdt Saturday for zone 645. (see laxmwwlox).
Small craft advisory in effect until 3 am pdt Saturday for
zones 670-673-676. (see laxmwwlox).
Hazard potential outlook (sat-wed)
an extended heat wave is likely across the area this weekend and
the first half of next week. Significant heat impacts will be
possible next week as well as elevated fire danger.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
