Marine Weather and Tide Forecast for Samsula-Spruce Creek, FL

DISCUSSION
Issued at 130 PM EST Sat Nov 29 2025

Tonight-Monday...High pressure across the Mid-Atlantic states lifts NE, with onshore flow prevailing, but weakening through the remainder of the weekend into Monday. Low level wind speeds will still be slightly elevated though, with sufficient low level moisture to continue the potential for isolated onshore moving showers. However, rain chances remain low (20-30%), with these PoPs primarily focused near to south of the Cape tonight through Sunday, and then across the entire coast and spreading inland toward Orlando on Monday. Onshore winds will also continue a gradual warming trend, with highs reaching the upper 70s to around 80 degrees Sunday and Monday. Lows tonight will range from the 60s along the coast to mid 50s to low 60s inland, and then will generally reside in the 60s both Sunday and Monday nights.

Tuesday...Mid to upper level trough pushing through the central U.S.
will aid in the development of low pressure along the northern Gulf coast Monday night. This low will shift NE and drag a cold front through the region late Tuesday into Tuesday night. Ahead of this front a band of convection will move through the region during the daytime Tuesday, with greatest chance for rain (up to 60-70%) near to northwest of I-4, with rain chances then decreasing to 30-50% farther south across east central FL. This activity should mostly be showers, due to limited instability, but LREF guidance still shows around 40-45% chance for SBCAPE greater than 400 J/kg, so isolated storms will also be possible. Increasing W/SW winds as high as 35-45 kt between 700-500mb north of Melbourne may lead to a few stronger storms, with the main threats being strong wind gusts to 40-55 mph.
Any storms will also be capable of producing lightning strikes and brief heavy downpours. Showers and storms will then shift offshore by Tuesday night as front moves through the region.

Highs will continue to rise ahead of the front into Tuesday, with values several degrees above normal in the low to mid 80s. Lows into Tuesday night will still mostly be in the 60s, except mid to upper 50s northwest of I-4.

Wednesday-Saturday...High pressure builds in behind the front and shifts eastward into mid to late week. Northerly winds Wednesday will gradually veer onshore into late week. Dry conditions are forecast to prevail Wednesday through Friday and then another approaching front will lead to a slight increase in rain chances (PoPs ~20-30%) on Saturday. Highs fall back into the 70s most areas on Wednesday and Thursday, and then rise to the upper 70s to low 80s Friday and Saturday. Overnight lows are forecast to range from the 50s to low 60s through the period.

Tonight-Sunday...Poor to hazardous boating conditions continue into this evening as easterly winds of 15-20 knots keep seas elevated.
The Small Craft Advisory will continue for the Treasure Coast waters through 10 PM this evening for seas up to 5-7 feet. Farther north across the Volusia and Brevard County waters, small craft should exercise caution due to the breezy onshore winds and seas 4-6 feet.
Winds will diminish overnight tonight into Sunday, gradually decreasing to 10-15 knots, initially north of the Cape and then across the entire waters into Sunday. Small craft will still need to exercise caution across the Treasure Coast waters overnight tonight into early Sunday morning for lingering seas up to 6 feet. Isolated to scattered showers will continue to be possible across the waters.

Monday-Thursday...Onshore winds around 10-15 knots continue into Monday, with seas 3-5 feet. A cold front will approach and move through the waters late Tuesday into Tuesday night, with boating conditions deteriorating. S/SE winds will increase to 15-20 knots Monday night into early Tuesday, veering to the SW into Tuesday afternoon. This will build seas to 4-6 feet Tuesday. As the front pushes through winds become W/NW initially up to 15-20 knots but quickly decrease to 10-15 knots as they become more northerly late Tuesday night into Wednesday. Winds are then forecast to generally remain around 10 knots out of the N/NE into Thursday. Seas up to 6 feet will continue offshore into Tuesday night/early Wednesday, but then decrease to 3-5 feet into midweek.

Isolated to scattered showers will continue through Monday/Monday night and then a band of showers and potentially a few storms will push through the waters ahead of the front Tuesday into Tuesday evening. Drier conditions are then forecast Wednesday-Thursday.

Increasing low-level moisture is leading to a broken deck of VFR stratus confined mainly to FL035-FL050 that will persist through much of the day into tonight (especially closer to the coast). Otherwise, breezy east winds with peak gusts of 22-25 knots along the coast will subside after sunset, especially over interior terminals where they are also expected to back to the northeast overnight. There is little to no signal for fog overnight at this time, with meager chances confined to terminals north and west of our area.
