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.

Dry and mild today as high pressure pulls away from the region.
The weather then becomes rather unsettled for Tuesday and
Wednesday with potentially heavy rain. Relatively strong gust
winds are likely on Tuesday. Dry weather returns for late week
into the weekend.
Near term until 6 pm this evening
Unseasonably warm and fair weather continue today. Just some cirrus
filtering sunshine, with temps still about 15 degrees above
normal in the mid to upper 70s. Temps are expected to fall
short of records by a few degrees along the coast, and several
degrees for the nyc nj metro.
Short term 6 pm this evening through 6 pm Monday
Low level moisture increases tonight with a light SE flow.
Models suggest stratus moving in with better chances of at least
a broken deck occurring west of eastern LI and ct. This leads
to a partly to mostly cloudy Monday. There appears to be enough
isentropic and low level lift for a chance of a sprinkle in the
afternoon as there's significant subsidence above 800 hpa
causing stratocu to spread.
Highs will still range mostly 70-75.
Long term Monday night through Saturday
Nwp remains on track with a deep upper level trough with strong
meridional flow approaching the region Monday night as the jet
dives into the southeast. The question that remains is the
timing of the very slow moving frontal passage. The GEFS has
about 10 members that support the slower deterministic ecmwf
timing. Thus, a good chance for rain to continue through
Wednesday especially on long island and ct.
Then, mainly dry weather is expected by Thursday night through
Winds are a potential issue Tuesday through Tuesday evening.
There is a low level jet ahead of the cold front and the models
have pretty good agreement with the 50-60 kt magnitude. Thinking
of gusts of 35 to perhaps 45 kt.
Have kept the tstms for Tue aftn and evening with potential for
long narrow cape.
Aviation 13z Sunday through Thursday
Vfr through at least 06z Mon as high pres gradually moves east
S SE winds 8-12 kt develop later this morning and afternoon
with seabreeze enhancement at coastal terminals.
Aft 06z tonight, the second night of onshore flow, may start
seeing indications of fog and or stratus development, however
the high may not be far enough offshore for MVFR ifr cigs. High|
clouds could also limit fog development. Would like to see more
of the hi-res guidance later today before committing to ifr
Outlook for 12z Monday through Thursday
Mon Morning MVFR ifr possible in stratus fog, thenVFR. S se
g20 kt Mon aftn.
Mon night-tue Potential a period of S SE g30-40 kt with llws
ssw 45-55kt@2kft for coastal terminals. MVFR ifr developing in
-radz Mon night, continuing with shra and low prob sparse tsra
Tue night-wed Ifr possibly continues in shra Tue night,
improving to MVFR wed.
Wed night-thu Vfr, with iso-sct MVFR in shra.
Quiet conds on all waters through Mon as high pressure over the
area slowly shifts east. The pressure gradient will begin to
tighten on Mon as low pressure strengthens over the great lakes.
Sca conds are expected to develop Mon night with the potential
for gale force gusts Tue into Tue night, all waters. The gale
potential will depend on mixing over the waters, but should be
able to mix down 35-40kt forecast at 1000mb, especially over the
ocean. Winds just off the deck may be slightly weaker on the
non- ocean waters and gales may only occur with any heavier
Winds will slowly diminish from W to E Tue night, and the
progression of the front LLJ will determine the end time for the
sca gale hazards. May need to keep headlines up into Wed for the
eastern waters. Seas on the ocean are forecast to remain above
5 ft through thu, due to a SE swell from a good fetch around
the departing high. This could be overdone however.
Expect nuisance urban ponding late Tuesday into Wednesday,
especially across the ny metro, long island and southern ct.
Storm total of 1.5 to 3" now expected, but flash and river
flooding are not anticipated.

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.
