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 long island waters and new york harbor.. A cold front will pass across the coastal waters overnight and settle south of the area by Friday night. The front will remain stationary through the day on Saturday before returning north as a warm front Saturday night into Sunday. Multiple waves of low pressure move through the area through early next week, followed by building high pressure for the mid to late week.

Mainly dry conditions are expected through Friday in the wake
of a cold front, however, hot and humid weather will continue.
A warm front will approach late Saturday and lift north across
the area into Sunday morning. Multiple waves of low pressure
move through the area through early next week, followed by
building high pressure for the mid to late week.
Near term until 6 am Friday morning
In the wake of the convective activity, patchy fog may form in
areas that received heavier rain and temps cool to near the
Weak front has settled across eastern portions of the area late
Lows tonight will still be in the upper 60s in the coolest
spots well north and west of the city with readings in the mid
to upper 70s in more urban areas.
Short term 6 am Friday morning through Saturday night
West to northwest flow aloft sets up for Friday as the front
drifts on south and stalls toward the DELMARVA peninsula. Drier
air aloft should mix down a bit as the flow aloft remains
offshore to 925 mb. However, this flow aloft is light (10 kts or
less) that the seabreeze will likely return in the afternoon
which would bring dewpoints at the surface back up. With the
offshore flow I have favored the warmer end of guidance and
gone with the higher end of mos. This will push temps to near 90
over well inland areas and into the low to mid 90s along the
coast and in and around immediate nyc and urbanized areas in
north jersey. Thus the heat advisory was extended for most areas
today except for rockland, westchester, western bergen and
southern fairfield counties which look to fall just short of
Although moisture and some instability lingers I have kept the
forecast dry as the presence of a lee-side surface pressure
trough and seabreeze do not look to be enough to pop any lid to
trigger convection tomorrow.
Dry for Friday night with west northwest flow aloft holding
firm. Lows should be a little cooler, with readings in the low
to mid 60s well north and west of the city to the mid 70s in nyc
and hudson county, nj.
I'm not enthused much for convection during the day on Saturday.
Westerly flow aloft sets up and a surface stationary front is
well to our south. Again, the only triggers will be the lee side
surface pressure trough and the sea breeze. I left in a low end|
slight chance of a shower or thunderstorm along the sea breeze
on long island and over interior areas where differential
heating of the hilly terrain may set off something. Highs will
be a bit cooler and many spots will only be in the 80s for a
high. However, humidity will still be enough to make it a sticky
The warm front should start to lift back north Saturday night
and return the potential for showers and thunderstorms from the
south and west. Models show a spread in timing, so i
broadbrushed in pops for this time frame. The better chance
should be closer to sunrise on Sunday as a low-level jet of
40 kts+ moves from the jersey shore toward long island. With
high pwat values approaching 2 inches per the gfs, the threat
for heavy rain will be there Saturday night along with gusty
winds in any more potent convection. Lows will be a little
warmer due to the increase in clouds and warm front lifting
Long term Sunday through Thursday
Much of the extended will be dominated by an unseasonably south
latitude polar jet orientation, with multiple short waves moving
through the northeast in northwest flow, which is typically a
pattern that offers very little predictability.
Despite considerable uncertainty for the extended period, the
pattern remains favorable for periods of heavy rainfall and
thunderstorms as multiple mesoscale convective systems move through
the area in northwest flow. The greatest complexity with the
forecast remains on where any frontal boundaries stall, which have
impacts on temperature, wind, instability, cloud cover, etc, but
most importantly on where exactly these systems will track. The
forecast will need to be monitored over the next few days for any
heavy rainfall flooding and severe potential.
By mid week, a brief respite in the active wet pattern may come as
ridging builds aloft and confluent flow allows a surface high to
strengthen. At least briefly, dew points and subsequently relative
humidity values will finally fall to more comfortable thresholds.
However, this may be short lived as the overall pattern still looks
to be active.
Aviation 02z Friday through Tuesday
Vfr. Patchy fog and stratus may develop after 08z but confidence
is too low to include in terminals at this time.
W flow around 10 kt becoming light and variable overnight
before increasing again late Friday morning. By mid
afternoon Friday, some occasional gusts up to 20 kt possible at

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.
