Marine Weather and Tides
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.
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.

Synopsis Upper low off the coast will keep temperatures below
normal through the end of the work week and into the weekend. Some
coastal drizzle or very light showers possible later tonight
through early Saturday as the upper low moves onshore, however
most areas will remain dry with below normal temperatures being
the main impact. Cool and dry pattern continues into early next
Discussion As of 3:27 am pdt Thursday... Marine layer now in
excess of 2000 feet with fog product showing another good push of
stratus into most inland valleys. Upper low well off the coast is
responsible for the deep marine layer and below normal temperature
pattern. Unseasonably cool highs today with 60s near the
coast bays and only some low to mid 70s inland. The low will
slowly approach the coast tonight into Friday. As this occurs some
coastal drizzle may occur as the marine layer continues to deepen
overnight into Friday as initial vorticity lobs passes over the
Core of upper low looks to move onshore near CAPE mendocino on
Friday with continued slight chance of some coastal drizzle in
deepening marine layer environment. Light showers associated with
the instability aloft will be confined to the far north bay,
mainly later Friday night Saturday morning. Daytime highs Friday
and Saturday continue to be unseasonably cool with deep marine
layer, substantial clouds and a cool airmass aloft leading to lots
of daytime highs only in the 60s throughout the bay area.
The main low finally ejects eastward late Saturday night into
Sunday. So for the weekend Sunday looks to have more sunshine and
slightly warmer temperatures.
Longwave trough stays over the west coast with a cold but dry
shortwave dropping towards the central coast by Monday and
Tuesday. This will continue to keep temperatures on the cool side
of normal through the end of the month but no precip expected with
this upper level shortwave. Modest warming and drying trend by the
middle of next week but no hot weather nor storms of note in|
Aviation As of 4:45 am pdt Thursday... Southwest flow enabling
another marine stratus intrusion this morning. Advancing low
interacting with stratus deck has resulted in higher bases
(500-800 feet higher than yesterday morning) and will likely
result in slightly earlier mix outs versus yesterday morning. In
addition, southwest flow with higher decks has allowed for a hole
in the deck to form over ksfo and most of the northern san
francisco bay. Otherwise, a few passing high clouds this morning,
stratus returns tonight, generally light onshore winds with
locally breezy gusty conditions this afternoon early evening.
Vicinity of ksfo... Southwest flow and higher bases working against
cigs at ksfo this morning, however, not uncommon to see these
types of holes in the deck fill in at or around sunrise. Watch
satellite and see what happens approach in full effect. Otherwise,
a few passing high clouds this morning, sustained winds up to
around 15k this afternoon, with an odd gust or two to around 20kt
possible. Lower CIGS potentially return late tonight into sunrise
Sfo bridge approach... Similar to ksfo.
Monterey bay terminals... MVFR through mid to late morning. Some
model data suggests ovc- bkn MVFR CIGS all day but currently not
look that pessimistic given southwest to west flow unfavorable
for lingering stratus over terminals.
Marine As of 04:39 am pdt Thursday... Generally light west to
northwest winds, but also locally breezy near coastal gaps and
prominent points later today. Light to moderate seas will
continue through the forecast period with a mixed south and
northwest swell developing late in the week.

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.
