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.

415 am edt Sun sep 24 2017
Today and tonight: large, but relatively weak upper level low is
centered across the northern gulf coast this morning while
hurricane maria continues to move to the north well east of the
bahamas. The upper level low is forecast to meander a little west
today, while maria continues it's trek to the north with no threat
to florida. Special 06z mfl sounding shows pwats remaining on the
high side of normal around 1.9" with seasonable midlevel temps
around -6c. However analysis shows a little drier air, the result
of subsidence around maria, just to our east that will advect
across the region later today.
It looks like ongoing isolated activity over the atlantic east coast
will continue through the morning hours, becoming more scattered
over the interior later this afternoon. Best coverage will generally
be just inland from the gulf coast where the diffuse east coast
breeze will collide with the gulf breeze. Overall coverage, as well
as the heavy rain threat will be less than yesterday as instability
and moisture will be lower. Showers and storms diminish over land
after sunset, with isolated activity over the waters tonight.
Upcoming week: hurricane maria will continue moving northwards,
paralleling the us east coast into midweek. Midlevel flow will
become more westerly across the region as the hurricane moves north
of the region on Monday. The mid-upper level low that is currently
meandering around the northern gulf coast is forecast to be absorbed
into the larger circulation around the storm by midweek, leading to
a trailing trough across the florida peninsula.
Models now show this trailing trough digging back across the
southeastern gulf mid-late week, with flow backing southwesterly a
little earlier on Wednesday night. It looks like a pretty sharp
moisture gradient will setup over south florida, with a very dry
airmass from lake okeechobee northwards and higher moisture
lingering across extreme southern florida.
Tuesday and Wednesday are trending towards the driest days of the
week with little, if any, precip north of the i-75 corridor and
only isolated chances further south. More scattered pops are
expected across the area to round out the end of the week.
Marine The main marine concern through the upcoming week will be
a reinforcement of long period northeasterly swell in the local
atlantic waters. As hurricane maria lifts north of the bahamian
islands later today, models show a continuing increase in seas,
building up to 8ft off the palm beach county coast by this
evening and potentially higher into Monday and Tuesday. This will
be with swells reaching 4-7ft at 12-13 seconds. Seas are expected
to peak at 5-7ft for the broward and miami-dade waters on Monday|
Based on these trends a small craft advisory remains in place for
the palm beach county waters through Monday afternoon, though it may
need to be extended in time as swell continues into midweek. For now
it doesn't look like it will need to be extended further south.
Gulf waters remain 2ft or less through the week. Light
northeasterly winds for all the waters today become more north-
northwest for Monday and Tuesday, then westerly into midweek.
Beach forecast Increasing northeasterly swells will result in
strong rip currents along all the atlantic beaches through much of
the upcoming week. A high risk for rip currents remains in effect
for palm beach county today, which will likely have to be extended
further south into broward and potentially miami-dade later this
afternoon as the higher swells arrive.
With the northeast swell forecast to build to 5 to 7 feet with
periods 12-13sec, there will be the potential for breakers reaching
8-10ft in palm beach county. Current timing has the largest swell
arriving towards daybreak Monday, so have held off on issuing a
high surf advisory. With the recent passage of irma, many
beaches have already seen considerable beach erosion, so more
impacts may been seen even at lower breaker heights.
Aviation Northeast winds of 5 kts or less will continue over all
of south florida TAF sites early this morning before increasing to
around 10 knots during the day hours. The only exception to this is
at kapf TAF site where the winds will become westerly after 18z
today. Vcsh will continue for the east coast TAF sites until 14 15z
then vcts until 00z. Kapf TAF site will see dry weather until 18z
then vcts until 00z today. The ceiling and vis will remain in the
vfr conditions, but could fall down into MVFR conditions with any
shower or thunderstorm passage.

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.
