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 800 PM EDT Mon Jul 13 2020
AVIATION. [Through 00Z Wednesday]
VFR conditions will prevail at the regional terminals through at least 17Z Tuesday. Westerly surface winds will remain sustained at 5-10 knots early this evening, with sustained speeds around 5 knots continuing overnight through Tuesday morning. Showers and thunderstorms are expected to develop after 17Z near the regional terminals, with a slow eastward storm motion initially through the mid to late afternoon hours. The Atlantic and Gulf coast sea breezes will develop during the early afternoon and will push inland, resulting in surface winds shifting to easterly and increasing to 10-15 knots outside of thunderstorm activity at SGJ by 18Z and then east-southeasterly at CRG and SSI towards 19Z, with sustained southwesterly surface winds increasing to near 10 knots at GNV and VQQ towards 20Z.
PREV DISCUSSION [328 PM EDT].
NEAR TERM [Through Tonight].
Convection is nil or near nil over the region this afternoon due to warm temperatures aloft (-6C at 500 mb). There is subtle hint of convergence along the First Coast late this afternoon with a surface trof right along the coast. This may bring a renegade pop- up shower or two late this afternoon with perhaps a clap or two of thunder. Otherwise, muggy conditions this evening into the overnight hours. Lows will be in the mid/upper 70s. The prevailing southwest flow which may develop some overnight showers and isolated storms over the NE GOM and the Big Bend Region of FL which may push inland to the I-75 corridor of inland NE FL toward sunrise.
SHORT TERM [Tuesday Through Wednesday Night].
Tuesday will be a similar set up as far as low-level flow pattern goes with a southwesterly flow with low level ridge axis near the FL Keys. Even more moisture recovery Tuesday will result in higher PoP coverage with the early morning showers coming in off the Gulf, transitioning to convective activity favoring interior counties by late morning and early afternoon, pressing toward the coastal FL and GA the remainder the day. Precipitable water values will climb into the 1.8 to 2.0 range for most of NE FL with PWATS about 1.6 to 1.8 over SE GA. Scattered to numerous showers are forecast for NE FL with mainly widely scattered coverage for SE GA.
On Wednesday, there will be a high pressure over coastal New England and another area of high pressure over the NE Gulf of Mexico. This pattern will bring lighter winds conducive for both the east coast and west coast seabreezes developing. With this said highest convective coverage will be across the interior counties between I-95 and I-75 with a collision of sea breezes likely to occur. PoPs 55-65% west of I-95. There is a potential for a few storms to become strong to marginally severe by mid to late afternoon into very early evening.
Daily high temperatures during this period are expected to reach into the lower to mid 90s with peak heat index values ranging between 100-108 degrees. Overnight low temperatures are expected to be in the mid 70s for midweek.
LONG TERM [Thursday Through Monday].
The western Atlantic ridge will be a further north with axis extending into south central GA while another area of high pressure will encompass Appalachian region. This pattern will bring a deep onshore flow pattern which will favor the east coast sea breeze development in the late morning to early afternoon, yielding diurnal convection across the interior and then pressing towards the western CWA during the mid to late afternoon through the early evening. Temperatures for the end of the week and into the weekend are expected to be slightly above the climatological average.
Trof axis down the SE US coastline will keep mainly offshore flow at 10-15 knots with seas 2-4 ft through mid-week with local onshore sea breezes along the coast. As the trof axis breaks down during the mid-week time frame, it will get replaced a weak High pressure ridge north of the waters and expect a more onshore east to southeast flow to develop by Thu/Fri time frame. No headlines.
Rip Currents: Low Risk of Rips continues in the offshore flow with surf/breakers in the 1-2 feet range through Tuesday.

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.
