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 146 AM EDT Sun Mar 29 2020
AVIATION. [Through 06Z Monday]
MVFR visibilities are expected to develop at VQQ and GNV towards 08Z. IFR conditions are then expected at VQQ and GNV after 10Z, with periods of LIFR possible around sunrise. A brief period of MVFR visibilities is possible at JAX around sunrise. Otherwise, VFR conditions will prevail at the regional terminals by 14Z. Sustained southerly surface winds around 5 knots will develop towards 14Z and will shift to southwesterly around 10 knots by 16Z. The Atlantic sea breeze will develop and move across SGJ towards 17Z, SSI after 18Z and CRG towards 20Z. Surface winds will shift to south-southeasterly in the wake of this sea breeze boundary at these terminals, with sustained surface speeds increasing to 10-15 knots.
PREV DISCUSSION [926 PM EDT].
NEAR TERM [Through Tonight].
Synopsis . High pressure aloft will remain over the region through the weekend, keeping well above normal temperatures and rain-free conditions in place.
Tonight: 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, spreading northward into inland SE GA through sunrise and dense fog advisories may be needed again if it becomes widespread. Lows will be in the mid 60s.
SHORT TERM [Sunday Through Monday Night].
Sunday: Strong mid/upper level ridging over the Central Gulf of Mexico through the Florida peninsula continues to dominate our weather pattern. The region will remain characterized as hot and dry as a subsidence inversion above the surface keeps our region suppressed and rain free. Seabreeze development will be pinned mainly along the coast somewhat dampening the effects of heating near the beaches, but overall all locations will experience very warm and above average and record temperatures. Highs once again in the lower/middle 90s inland and the beaches will be in the upper 80s/near 90 degrees as sea breeze struggles to develop late in the day.
Sunday night: High pressure ridge at the surface and aloft gets shunted a tad southward as weak frontal boundary with very little moisture pushes south near the FL/ GA border region Sunday Night. Lack of moisture will keep rain chances near nil. Minimums will be above normal with lows in the 60s.
Monday and Monday night: The frontal boundary will linger and around the I-10 corridor as a weak residual boundary. A zonal flow aloft will persist over the region as a short wave trof moves into the Lone Star State. Weaker SW flow will allow for sea breeze fronts to push further inland for slightly cooler temps at the Atlc beaches in the lower 80s, but highs into the lower 90s will continue over far inland areas. By Monday night, the aforementioned short wave trough moves into the ArkLaMiss region with attendant front moving into western Mississippi. High clouds will start increasing late Monday night. Lows Monday night will be in the 60s.
LONG TERM [Tuesday Through Saturday].
Tuesday and Tuesday night: A low pressure system will develop over the SE US on Tuesday and deepens as it tracks into the Carolinas Tue evening. This will lead to one more day of above normal heat with highs in the mid to upper 80s area-wide with breezy SW flow ahead of the trailing cold frontal passage expected by Tuesday Night. SPC has portions of the Suwannee Valley and SE GA in the Day 4 outlook for a severe potential. Precipitable water values rapidly increase Tuesday afternoon and evening between 1.50 and 1.75 inches with CAPES increasing (750-1000 J/kg) with decent low level shear. Pre-frontal showers and storms can be expected with potential for isolated severe storms, with best chances of rainfall and localized severe weather across SE GA with lessening storm impacts and rainfall coverage into NE FL. The front should push south of the area Tuesday night with cooler and drier air filtering into the area.
Wed-Sat . overall cooler conditions mid week as high pressure system builds north of the area over the TN and Ohio Valleys. behind the cold front. Generally progress flow aloft with ridge aloft moving through the ern U.S. Thursday night and Friday. As a result, a sfc ridge will push offshore of the Carolinas allowing low level winds to veer and airmass to moisten and warm a bit. A series of shortwaves will push into the MS and Ohio Valleys early Friday and into the southeast states Friday night through Saturday. Associated isentropic ascent aloft and an approaching cold front will lead to increasing rain chances into Friday and Saturday. Have capped POPs at 20-30 percent for now due to a few differences in how the GFS and ECMWF handle this system. Temps will be closer to climatology with highs in the 70s to some lower 80s. Min temps in the 40s to lower 50s Thursday morning will moderate to the lower to middle 50s as clouds increase through latter portions of this period.
High pressure ridge will remain well offshore through late Sunday continuing south-southwest flow with speeds near 15 kt to 15-20 kt tonight with SCEC headlined. Winds should gradually weaken to near 10-15 kt late Sunday night as the pressure gradient weakens. Weak frontal boundary still slides through the waters Sunday night with a shift to light onshore flow on Monday. Winds will become southwest again Tuesday as a strong cold front approaches. Frontal passage looks to be Tuesday night, with potential for Small Craft Advisory, with highest confidence for these conditions offshore waters. Gusty northwest/north flow expected to develop behind the front on late Tuesday night and into 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.
Min humidities will bottom out in the 30-40 percent range through Sunday but remain above critical levels. Dispersions will a bit elevated for parts of southeast GA rest of today and Sunday. Lower dispersion values area-wide on Monday.
At this time, we are not anticipating a whole lot of rain with the cold frontal passage on Tuesday/Tuesday night with average rainfall amounts roughly in the range of 0.15 to 0.45 inches in southeast GA and lower values for northeast FL.

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.
