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.

Synopsis for the far southern california coast.. At 1 am, a 1022 mb high was over idaho and a 1009 mb low covered the southern california coast. Offshore flow will prevail during nights and mornings followed by brisk northwest winds during the afternoons. Some coastal eddy circulation will get into the mix today into Wednesday. Offshore flow weakens Thursday and turns onshore this weekend.

309 am pdt Tue sep 26 2017
High pressure over the great basin will bring offshore flow through
Wednesday with sunny, warm days and cool nights. Winds will be
gusty at times in the mountains, foothills and the inland empire.
Warmer Thursday and Friday with lighter winds. Later today, a weak
eddy circulation offshore may bring a return of coastal low clouds
and fog each night and morning through Thursday. Cooler by the
weekend as onshore flow returns.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
skies were clear over the CWA at 3 am pdt. Some low, marine clouds
were observed along the baja coast, well south of san diego, and
high clouds were thickening and streaming rapidly south over eastern
ca western nv. These clouds mark the shortwave that will amplify the
trough over us later today and tonight. Surface pressure gradients
were holding very weakly onshore ksan to the lower deserts, and
about 6 mbs from SW nv. N-ne winds continued in some mtn areas at 3
am pdt with local peak gusts to 25 mph, but in general, winds were
Gusty n-ne winds are expected again this morning over, mainly
northern portions of the CWA with a moderate sfc pressure gradient
in place. The gradient will be weakening later today as a shortwave
trough digs south, forming a cut-off upper-level low pressure center
over SE ca. The low may have a hand in spinning up a coastal eddy.
Numerous hires model runs, and even dew-point guidance in mos,
suggests this may happen today or tonight. The eddy would draw a
moist marine layer north along the coast, beneath the dry,
continental air, possibly resulting in areas of low clouds and fog
for Wed Thu mornings along the coast.
Aside from that little event, weak offshore flow prevails through
Friday as the longwave trough, which has been over the west since
last week, finally lifts out. That keeps inland areas quite dry and
warm through Friday with daytime temperatures several degrees above
average. Global model solutions begin to diverge over the weekend,
but are showing another, weaker amplitude trough digging into the
west. This pattern will weaken the sprawling sfc high over the west|
and replace it with sfc low pressure and an onshore flow pattern.
Look for cooler weather and more marine influence with periods of
low clouds and fog developing inland.
Gfs ECMWF 00z solutions diverge widely next week lowering forecast
250900z... Mostly clear skies today through tonight. Pockets of
breezy northeast winds will produce intermittent and isolated llws
in the foothills of the santa ana mountains and south of the cajon
pass through 21z today. Kont and ksbd may be impacted at times.
No hazardous marine weather is expected through Friday.
North-northeast winds are currently only gusting to around 20-25 mph
at a few locations, but should strengthen again this morning.
Strongest winds will be in and below the cajon pass, and over the
santa ana mts canyons with local gusts 30-35 mph. Winds will be
lighter over san diego county. Daytime minimum rh will be near 10-15
percent. This could result in a few hours of near critical fire
weather conditions in the wind prone areas. The duration of this
condition will be too short and isolated to support the issuance of
any fire weather products.
Rh is forecast to increase Wednesday through Friday over coastal and
western valley areas, but minimum rh will still fall to 15-25
percent across the far inland valleys. Overnight recovery will be
better, and northeast winds will be weaker as well during this time.
A general onshore flow pattern will return this weekend for cooler
conditions and higher daytime humidity.
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
