Area Forecast Discussion
National Weather Service Charleston SC
212 AM EDT Tue Apr 14 2026

.WHAT HAS CHANGED...
The Aviation Section has been updated for the 06Z TAF issuance.

&&

.KEY MESSAGES...
- 1) Dry weather and above-normal temperatures expected to
  continue through the weekend.

&&

.DISCUSSION...
KEY MESSAGE 1: Dry weather and above-normal temperatures
expected to continue through the weekend.

No significant changes to the forecast with prominent ridging aloft
and subtropical high pressure at the surface. This setup will yield
a rain-free forecast with well-above average temperatures across the
region for the next 7 days. Temperatures will range into the mid 80s
to low 90s today through the weekend. These values would be on the
order of 10 degrees (or more) above normal. High temperatures could
approach the daily records this afternoon, with the best chances of
reaching records late this week and into the weekend (see Climate
section below). The beaches will feel considerably cooler (possibly
10 to 15 degrees cooler) with onshore flow and water temperatures
remaining in the mid-60s. The combination of well above normal
temperatures and no rainfall will only serve to further worsen
ongoing Extreme (D3) drought conditions highlighted by the U.S.
Drought Monitor.

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
14/06z TAF Discussion:
KCHS/KJZI/KSAV: VFR for much of the 06z TAF period. Some shallow
ground fog could develop just before daybreak. The highest risk
for fog will occur at KSAV and KJZI. No meaningful impacts are
expected, although a brief period of MVFR vsbys could occur.

Extended Aviation Outlook: VFR.

&&

.MARINE...
The forecast philosophy remains the same with no major concerns
through Saturday. Bermuda high pressure centered well offshore will
maintain its influence through the week with a broad southerly flow
regime prevailing. This pattern favors sea breeze surges this
afternoon, mainly along the land/sea interface and Charleston
Harbor.

Rip Currents:
Today: A low risk for rip currents was maintained for all beaches
for today given slightly lower swell heights are anticipated. With
sea breeze enhanced winds likely at the beaches with ongoing 10
second periods, the situation is very close to tipping into the
moderate risk range. The situation will be monitored throughout
the day and an upgrade to a moderate risk may eventually be needed.

Wednesday: Slightly higher swell heights are poised to arrive
Wednesday with ongoing periods of around 10 seconds, particularly
along the Georgia and far southern South Carolina beaches. A
moderate risk for rip currents was highlighted for all beaches even
though local rip current scores are running right around the
low/moderate risk threshold.
