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 over the area through tonight slowly retreats to the east Tuesday night and Wednesday as hurricane maria moves northeast off the mid-atlantic coast. Refer to the latest national hurricane center advisories for the official forecast of maria. A cold front crosses the tri-state Wednesday night, followed by high pressure building in from the west through Thursday night. Another cold front approaches from the west Friday, then crosses the area Friday night.

High pressure prevails through Tuesday then slowly retreats to
the east Tuesday night and Wednesday as hurricane maria moves
northeast off the mid-atlantic coast. Refer to the latest
national hurricane center advisories for the official forecast
of maria. A cold front crosses the tri-state Wednesday night,
followed by high pressure building in from the west through
Thursday night. Another cold front approaches from the west
Friday, then crosses the area Friday night, followed by canadian
high pressure building in for the upcoming weekend.
Near term until 6 pm this evening
The forecast is on track with no major changes made to the near
Deep layered ridging over the region will result in a sunny day
with above normal temperatures. Some low stratus may however
roll in late in the day right along the coast. 850 mb
temperatures are forecast to be around 17c, so highs away from
the sea breeze will be well into the 80s with perhaps a few
spots reaching 90. Even the coolest spots should be able to
reach at least into the upper 70s in spite of a sea breeze.
Highs will likely fall short of records, however. See the
climate section below for more details.
There is a high rip current risk at the ocean beaches through this
evening due to southerly swells from hurricane maria. Will also keep
up the high surf advisory for the south shores of suffolk county
today into this evening, although it looks like widespread surf
heights might not reach 7 feet across the area. Not enough
confidence to drop the advisory altogether.
Short term 6 pm this evening through 6 pm Tuesday
The high surf advy and high rip risk have been extended thru tue
ngt. Also, fog has been expanded for tngt with stlt indicating
it is approaching ERN li already.
Looks like low stratus and fog will push in from the ocean as
tonight progresses. Models suggest just enough turbulent mixing to
preclude widespread dense fog, but there is a chance that a few
spots end up with dense fog before the night is through. Clouds will
help keep low temperatures above normal.
The tricky part of the forecast for Tuesday comes from the
uncertainty of the magnitude of stratus and fog that happens
tonight. Models at least appear to be in agreement that there will
be less lower level moisture during the afternoon hours. Inland
areas will have a better chance of seeing lower clouds break up
sooner in the day, but there could still be a pretty good deal of
cirrus from hurricane maria. Temperatures aloft will still be quite
warm under high pressure, so in spite of the cloud cover, expecting
high temperatures to be above normal once again.
There likely will be a high risk of rip currents at atlantic
beaches through at least Tuesday.
Long term Tuesday night through Sunday
The axis of a northern stream shortwave ridge passes to the north
Tuesday night, with associated subsidence keeping things dry. Lows
Tuesday night should be around 10-15 degrees above normal.
A northern stream trough passing to the N Wednesday and Wednesday
night, should help create a sufficient weakness in the ridge to the
east of hurricane maria, to allow the storm to track well SE of long
island. There could be some isolated to scattered showers due to a
combination of some moisture from maria and the passing shortwave.
The associated cold fronts passage late Wednesday night could
provide enough lift for a rumble of thunder or two as well. Highs
Wednesday should be around 10 degrees above normal and lows
Wednesday night around 15 degrees above normal.
Wsw-sw flow aloft settles over the area Thursday-Friday, helping to
continue to push maria well offshore. Do have slight chance pops
Thursday and Thursday night (diminishing from W to e) as there is
some question on exactly how fast the surface cold front exits to
the east, and whether it could become anafrontal. Friday should be
dry, with the cold front expected to be well to the east and no
significant shortwave progged to move over the area.
A positively tilted trough approaches Friday night, then crosses the
area Saturday. This warrants slight chance pops, initially over w
zones late Friday night, then over the entire area by Saturday
afternoon. If confidence increases in the amount of low level
moisture available for the system to work with, pops could end up
needing to be raised to chance on Saturday.
Deep layered northern stream ridging then builds in behind the
departing trough. There is some question how fast it begins to
build in (as soon as Saturday night or waiting until Sunday) for now
went with a blended timing based on the ECMWF gfs cmc. It should be
dry regardless of the timing of the ridge.
Temperatures Thursday-Sunday start out above normal Thursday, should
be near normal Friday, then below normal Saturday and Sunday.
There probably will be a high risk of rip currents at atlantic
beaches through at least Thursday and possibly into Friday.
Aviation 18z Monday through Saturday
High pressure remains across the region through the TAF period.
Vfr conditions this afternoon, but watching stratus fog bank off
the coast. Stratus and fog will likely make a better push
across the terminals from the east this evening and overnight.
Stratus and fog is expected to be more widespread, however
timing is uncertain and could be several hours off from current
forecast. These subVFR conditions linger into Tuesday morning,
then improve as the afternoon hours approach.
Light E SE winds 5-10 kt through the remainder of the afternoon
become light variable again tonight into early Tuesday morning.

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.
