Marine Weather and Tide Forecast for South Daytona, FL

UPDATE
Issued at 820 PM EST Thu Jan 23 2025

The pressure gradient remains tight, especially over the coastal and marine areas, this evening. Northerly winds at 10-15 mph with gusts of 20-25 mph along the coast, and winds around 10 mph with gusts to 15-20 mph at times across the interior through tonight.
The KMLB radar shows some light showers ongoing across the interior as well as across the Atlantic waters. Accumulation is forecast to be less than a tenth of an inch.

Chilly with below normal temperatures forecast once again tonight, with the potential for patchy to areas of frost development in the traditionally cooler locations across Lake, interior Volusia, northwest Orange, and western Seminole counties. A Freeze Warning is in effect for northern Lake and interior Volusia counties from 3 AM to 9 AM Friday where sub freezing temperatures are forecast, with minimum temperatures as low as 31 degree. Overnight lows else where across east central Florida will be in the mid 30s to low 40s. A Cold Weather Advisory is in effect for Lake, Volusia, Orange, and Seminole counties from 3 AM until 9 AM Friday. The elevated winds will produce wind chill values in the mid to upper 20s north of I-4, with low to mid 30s to low 40s across the rest of the area. Forecast remains on track with only minor adjustments to the rain chances to account for ongoing showers, as well as expanded the patchy frost to include prone areas in NW orange and W Seminole counties.

Rest of Today-Friday Night...Scattered light showers continue to move from south to north across the area this afternoon, producing light accumulations. Developing long pressure near the Bahamas along the stalled boundary south of Florida will begin slowly push eastward tonight. Isolated to scattered showers will remain possible into this evening, mainly along the coast, before the low begins to pull higher moisture away from the area. An upper level trough will swing through the Florida peninsula Friday, dragging the low farther into the Atlantic. PoPs into this evening continuing around 20-30%, with the exception of the far interior, before dry conditions develop late tonight into Friday.

Cold temperatures are lingering around the area today, with high coverage of clouds leading to highs in the upper 40s to lower 50s.
In fact, record cool high temperatures currently being threatened at Leesburg, Orlando, and Melbourne. Temperatures will remain well below normal overnight, as northerly winds continue. Winds up to 10mph will make temperatures feel like the upper 20s to mid-30s across the area. The coldest spots look to be near and north of I-4, with a Cold Weather Advisory in effect for Lake, Orange, Seminole, and Volusia Counties. As the aforementioned low pulls away from the area, drier conditions will cause cloud cover to erode from areas north and west of I-4 by sunrise. Thus, the temperature forecast for this area has decreased slightly, with overnight lows near to slightly below freezing. A Freeze Warning has been issued for northern Lake and inland Volusia Counties.
Elsewhere, continued cloud cover is forecast to keep low temperatures in the mid-30s to lower 40s. Steps should be taken to protect sensitive plants and people or pets without adequate shelter.

Tomorrow, skies will continue to clear, as high temperatures look to finally reach the mid to upper 50s area-wide. Dry conditions prevail, with north to north-northwesterly winds 10-15mph. The upper level trough moving through the area into Friday night will provide one more nudge of cold air into east central Florida. As a result, the coldest night of the week is forecast Friday night into Saturday morning. Clear skies and lower dew points will allow temperatures to fall into the 30s everywhere but the immediate Space and Treasure Coasts. Northerly winds up to 10mph are forecast to produce wind chills in the mid-20 to lower 30s.
Another Cold Weather Advisory will likely be needed and for a greater portion of the forecast area. In addition, low temperatures in the upper 20s are possible north and west of I-4.
For now, have issued a Freeze Watch for Lake and inland Volusia Counties, which have the highest confidence in seeing freezing temperatures. Rural portions of Osceola County could also reach temperatures near freezing and this will need to be monitored for future updates, but it is lower confidence at this time.

Saturday-Thursday (modified previous)...High pressure builds into the southeast this weekend keeping dry conditions in place and veering low level winds onshore. This will lead to a gradual rise in temperatures after the cold start to Saturday. Highs will still be below normal into Saturday afternoon, reaching into the 60s, except upper 50s northern Volusia County. Lows Saturday night not as cold, but still in the 40s across much of the area, and upper 30s across normally colder locations northwest of I-4. Highs on Sunday will be a little closer to normal, in the upper 60s to low 70s, except low/mid 60s along the Volusia County coast. Lows then fall to the mid 40s to mid 50s Sunday night.

Warming trend then continues into next week as high pressure settles farther southward across the area. Mostly dry conditions look to persist through the extended, with highs either near to slightly above normal in the 70s and lows in the upper 40s to 50s.

MARINE
Issued at 243 PM EST Thu Jan 23 2025

Low pressure develops near the Bahamas along the stalled boundary south of Florida tonight, then moves eastward into the weekend.
Meanwhile, high pressure builds into the Deep South. Hazardous boating conditions will continue across the local Atlantic waters into Saturday morning. North to north- northwesterly winds 20 to 25kts will persist through Friday night, with a brief improvement for the nearshore Volusia County waters, late tonight into Friday afternoon, before conditions deteriorate again. Seas up to 7-8ft will be slow to improve, but will steadily diminish into Saturday morning. Small Craft Advisories are in effect.

Boating conditions look to improve this weekend into early next week, as high pressure establishes itself over the local area.
North to northeast winds prevail, remaining around 15kts or less through the period. Seas also diminishing from 4-6ft Saturday afternoon to 2-3ft by Monday. Showers are forecast to continue into Friday over the waters. Then, dry conditions prevail into mid-week.
