Marine Weather and Tide Forecast for Darien, GA

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

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

Prominent ridging aloft and subtropical high pressure at the surface will continue to support dry weather and above normal temperatures through the weekend. The biggest story will be temperatures as upper 80s and low 90s are expected Wednesday and Thursday, followed by low to mid 90s for Friday and Saturday.
Values along the immediate coast will be cooler thanks to the daily sea breeze, with the highest temperatures further inland.
The best chance of threatening daily record highs will come Friday and Saturday. See the Climate section below for more information. Unfortunately, no rainfall is expected which will only serve to worsen the ongoing drought across the region.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/
VFR conditions are expected to prevail at KCHS, KJZI, and KSAV through 0z Thursday. There could again be a period of shallow ground fog around sunrise on Wednesday and we have maintained the mention of shallow fog at all three TAF sites. By Wednesday afternoon, a sea breeze should advance across the terminals, turning winds from the south and increasing to 10 to 15 kts.

Extended Aviation Outlook: VFR.

MARINE
Overall, still no significant change to the forecast through Sunday across the local waters. Subtropical high pressure to the east will be the primary feature, driving south to southwest flow across the waters with speeds mostly in the 10-15 knot range. There will be some local enhancement along the land/sea interface and in Charleston Harbor each afternoon and evening with the sea breeze. A cold front will approach from the west late in the weekend and could produce some modestly stronger flow ahead of it Saturday and Sunday. However, it looks like the front will likely pass through the waters Sunday night and into Monday meaning that any significant surge will likely occur just beyond the current marine forecast time period. Seas should remain within the 2-4 ft range.

Rip Currents: A Moderate Risk of rip currents is expected at all beaches Wednesday and Thursday. The combination of 2-3 ft swell with a period of ~10 seconds and moderate onshore flow should be enough to increase the rip risk a bit.
