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.

Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 236 PM EDT Sun May 31 2020
SYNOPSIS. Dry and cool conditions will prevail across the area through Tuesday. Moisture and warmer temperatures return to the area on Wednesday ahead of an approaching cold front with isolated to scattered showers and thunderstorms possible each afternoon through the weekend.
NEAR TERM /THROUGH MONDAY/. As of 145 PM EDT Sunday: Absolutely gorgeous day continues as surface high pressure and drier air ooze into the forecast area in the wake of the frontal passage last night. Upper troughing in place over the eastern CONUS is keeping temperatures spring-like, roughly 5 degrees below average.
This afternoon, some scattered mid-level clouds are hanging out over the area, but convection remains suppressed everywhere outside the southwestern mountains, where the NW flow over the terrain has generated enough lift to create a decent CU field there. A few showers may be able to form, but with dry air in place, they will be very short-lived and any precip that forms may not even make it to the ground. Clouds will generally scatter out tonight, and temperatures will be near average. Surface high pressure will move closer to the area tomorrow, and that combined with dry air and upper troughing still in place over the eastern CONUS will combine for another dry and spring-like day.
SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/. As of 200 PM EDT Sunday: With sfc high pressure moving off the Carolina coast, upper ridging over the central CONUS will continue to deamplify and broaden through the fcst period as moisture slowly returns to the area from the GOM. As a result, Tuesday will be the last dry day as chances for isolated showers and thunderstorms return to the area on Wednesday as a cold front slowly drops southeastward through the OH Valley. Per latest guidance, anticipate activity to remain confined to the mountains. While max temperatures on Tuesday are expected to climb to just a few degrees below normal, values will near 90 degrees on Wednesday.
LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/. As of 230 PM EDT Sunday: As available moisture continues to infiltrate into the area and a cold front nears the area from the northwest, increasing chances for isolated to scattered showers and thunderstorms will expand across the area Thursday and Friday as max temperatures climb to around 90 degrees on Thursday and a few degrees cooler into Friday and instability increases, slightly cooler across the mountains. An unsettled weather pattern is expected to carry into the weekend as guidance progs the weakening front moving into the area with upper troughing digging slightly over the eastern seaboard and ridging amplifying over the central CONUS. Max temperatures in the upper 80s will continue.
Will note, as models continue to hint at the potential for tropical system development in the GOM, latest guidance continues to be well out of agreement both temporally and spatially. Something to keep an eye on over the next several days.
AVIATION /19Z SUNDAY THROUGH FRIDAY/. At KCLT and elsewhere: A few scattered mid-level clouds will linger through the afternoon hours, though precip is not expected at any TAF site with dry air and high pressure in place over the area. Mainly a wind forecast through the valid TAF period, with some NWrly gusts expected through this afternoon before winds die down in the evening and overnight hours. Winds will become light and sites will be restriction-free overnight and into tomorrow.
Outlook: VFR conds and light winds are expected to prevail into mid- week, although early morning restrictions may be possible in the mtn valleys. Increasing heat and humidity will likely result in a return of afternoon/evening convection by the end of the week.

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.
