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.

update... Clear skies and light winds have already allowed temperatures
to drop quickly across the region this evening. Naples and fort
lauderdale both set new record cool highs for the day. With naples
only reaching 59 degrees and fort lauderdale 62 degrees.
With good radiational cooling, we look on track for temperatures
to drop a few degrees colder than last night. The northwest
interior can expect mid- upper 30s, the gulf coast and remainder
of the interior low-mid 40s, and the east coast metro ranging from
the mid 40s for the western areas to around 50 right near the
coast, east of 95.
No changes to the ongoing forecast.

this afternoon through Monday: visible satellite imagery this
afternoon shows the extent of the cold air advection across the
florida peninsula. Gusty north- northwest winds encountering the
warm gulf and atlantic waters have lead to a robust stratocumulus
field over the water, but land areas remain dry. Given the time of
day temperatures have likely already maxed out in the mid-upper
50s, placing a few record cool highs in jeopardy for today.
Monday will be a repeat of today, with temperatures a few degrees
warmer in the mid-upper 60s with the potential for a few places to
make it over 70.
Winds diminish quickly as we head towards sunset, and with clear
skies expect temperatures to quickly drop this evening. Overnight
lows will likely be a few degrees colder than last night. The
northwest interior can expect mid-upper 30s, the gulf coast and
remainder of the interior low-mid 40s, and the east coast metro
ranging from the mid 40s for the western areas to around 50 right
near the coast, east of 95.
Tuesday through Thursday: additional shortwave rotating through
in the larger east coast trough will drive another frontal passage
late on Tuesday. With little moisture recovery between now and
then, don't expect more than a modest increase in cloud cover and
breezy west-northwest winds during the day on Tuesday.
The front will reinforce the cool and dry airmass in place across
the florida peninsula. While high temperatures on Tuesday will be
in the low to mid 70s, expect a dip where temperatures struggle
to get out of the 60s on Wednesday. Temperatures return back into
the low 70s on Thursday. Overnight lows will likely be coldest
behind the front Wednesday night, but generally remaining in the|
low-mid 40s across the interior, upper 40s for the gulf coast and
interior east coast metro, and low 50s for the immediate coastal
areas of the east coast metro.
Friday into next weekend: next system in the parade looks to
arrive late week. Timing and strength differences abound between
the GFS and ecmwf, but both show a more robust front arriving
Friday or Saturday. There seems to be a little better moisture
recovery ahead of this front, so this may be the next appreciable
chance of rainfall across south florida. Temperatures late in the
the week also look to be a little closer to normal in the mid-
Marine... High pressure will build east across the gulf of mexico
and florida early this week, allowing gusty north-northwesterly
winds and seas to subside below advisory cautionary criteria this
evening. A dry frontal passage will bring another surge of west
to northwest winds, potentially leading to hazardous boating
conditions again late Tuesday into Wednesday. No significant rain
chances are expected through most of the upcoming week.
Beach forecast... Gusty north-northwest winds will continue to
drive a high risk of rip currents for the beaches of collier
county this afternoon and a moderate risk along the east coast.
The threat is expected to subside along both coasts on Monday with
Fire weather... As the surface high builds across the gulf late
tonight, winds will quickly diminish across the region. The
relatively light flow and cool temperatures on Monday will lead to
very poor dispersions across all of south florida. Dry
conditions are expected to be in place for the remainder of the
week, with Monday likely being the driest day. Relative humidities
are expected to fall in the the upper 30s across the eastern half
of south florida , with values in the 25 to 30 percent range over
the western half. However, erc values are expected to remain in
the teens and lower 20s, so no headlines are expected this week.
Some improvement is expected on Tuesday, with values expected to
remain above critical levels. A slightly drier airmass will be in
place for the latter half of the week behind a dry frontal

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
