Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service Jacksonville FL 129 PM EDT Sat Mar 28 2020
AVIATION. [Through 18Z Sunday]
VFR conditions are forecast across the area through around 06Z. Another round of reduced cigs and vsbys is expected tonight/Sun morning over the Suwannee Valley and adjacent areas, likely including GNV between 09-14Z. Winds will be mostly around 10 knots or less and from the south along the Atlantic coastline, southwest near GNV, though gusts to 15-20 kts will be possible between 18-21Z along the coast with the afternoon seabreeze.
PREV DISCUSSION [856 AM EDT].
NEAR TERM [Through Tonight].
Early this morning: Moist Low level flow off the NE GOMEX will help to develop another round of dense fog across the Suwannee Valley/I-75 corridor of inland North FL and spread north into inland SE GA through sunrise and dense fog advisories may be needed again if it becomes widespread.
Today: Strong High Pressure ridge over the GOMEX/FL Peninsula will remain in place with all-time record heat expected for the month of March today with Highs in the lower/middle 90s inland and mid/upper 80s at the beaches with SE Atlc sea breeze pinned close to the coast. Dry airmass with PWATS less than 1" will prevent any shower activity.
Tonight: Mostly clear skies expected again underneath high pressure with lows in the lower 60s inland and middle 60s near the coast. More dense fog possible over inland areas once again towards sunrise Sunday morning.
SHORT TERM [Sunday Through Monday].
High pressure ridge at the surface and aloft gets shunted southward a bit as weak frontal boundary with very little moisture pushes south into the area Sunday Night and weak high pressure ridge builds back into the region on Monday. The increase in SW flow on Sunday will keep all-time record March heat in place with highs once again in the lower/middle 90s inland and pushes the heat towards the beaches where highs will be in the upper 80s/near 90 degrees as sea breeze struggles to develop late in the day. Lack of moisture should keep rain chances with weak front at 10% or less Sunday Night and above normal lows in the 60s. Weaker SW flow will allow for sea breeze fronts to push further inland for slightly cooler temps at the Atlc beaches in the 80s, but highs into the lower 90s will continue over inland areas.
LONG TERM [Tuesday Through Friday].
Tue & Tue Night: Models still in decent agreement on low pressure development over the SE US on Tuesday and intensifying as it tracks into the Carolinas Tue Night. This will lead to on more day of near record breaking heat with highs in the upper 80s/near 90 area-wide with breezy SW flow ahead of the trailing cold frontal passage expected by Tuesday Night. Pre-frontal showers and storms can be expected with potential for isolated severe storms, with best chances of rainfall and severe weather across SE GA with lessening storm impacts and rainfall coverage into NE FL.
Wed/Thu/Fri: A cooler/drier NW flow behind the front will lead to Max temps closer to climo values to start April mostly in the 70s to near 80 degrees. Lows will actually fall into the 40s over inland areas Wed Night, otherwise lows generally in the 50s through the dry period under Mostly Clear to Partly Cloudy skies.
Surface ridge will remain offshore with approaching weak front on Sunday to continue Southerly flow through the weekend. Speeds at 15-20 knots Today and Tonight with SCEC headlines will weaken to 10-15 knots on Sunday. Weak frontal boundary still slides through the waters Sunday Night with a shift to light onshore/NE flow on Monday. Winds become SW ahead on the next front on Tuesday and increase to potential Small Craft Advisory levels with the frontal passage Tuesday Night. Gusty NW/Offshore flow expected to develop behind the front on Wednesday.
Rip Currents: Moderate Risk for NE FL with surf/breakers at 2-3 ft, while Low Risk exists for SE GA with surf 1-2 ft.
Minimum humidities will fall into the 30-40% range each afternoon through the weekend, but remain above critical levels. Also the hot and dry conditions will lead to slightly higher daytime dispersion values.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
