Marine Weather and Tide Forecast for Hutchinson Island South, FL

DISCUSSION
Issued at 240 PM EDT Thu Oct 15 2026

Current-Friday... A moisture gradient exists across east central Florida this afternoon with the deepest moisture (PWATs 1.5"+)
identified from Cape Canaveral and the Orlando metro southward. This area of deeper moisture will favor the best rain chances southward today (20-40%) while areas north of Orlando remain dry. The moisture boundary lifts northward into tomorrow as a broad area of high pressure moves eastward and low-level flow gradually veers south to southwest. Rounds of isolated coastal showers are forecast along the Treasure Coast tonight, expanding northward along much of the coast late tomorrow morning. Increasing coverage of scattered to locally numerous showers and a few storms spreads inland through tomorrow afternoon with steering flow pushing back any activity towards the coast in the evening. Warm and humid conditions are expected tomorrow with above normal high temperatures around 90 degrees and peak index values near 100 degrees.

Saturday-Wednesday... A cold front passes central Florida on Saturday as a large area of high pressure builds over the eastern U.S. The cold front will then stall and linger south of the local area next week. A tightening pressure gradient will set the stage for a period of windy conditions and numerous coastal hazards. On Saturday, gusty northeast winds begin to spread southward across the region behind the front, and Wind Advisories may be needed for portions of the coast. Winds continue to strengthen Sunday, and sustained winds increase to 15-25 mph more areawide (locally higher along the coast). Moderate confidence (40-50% probabilities) exists in wind gusts exceeding 40 mph Sunday, and Wind Advisories will be likely to expand to include most inland locations. Some uncertainty exists within the synoptic pattern through the remainder of the extended forecast period as models suggest low pressure attempting to develop over portions of the western Atlantic. For now, a tight pressure gradient is forecast to persist, keeping breezy to windy conditions potentially into mid next week, especially along the coast. With a prolonged period of increased onshore flow, hazardous coastal conditions are expected. Rough surf, large breaking waves, and a high risk of life-threatening rip currents will be present at all area beaches. Entering the water is highly discouraged! Long period onshore swells will contribute to beach erosion, and Moderate beach erosion is likely, through multiple high tide cycles.

Deep moisture persists areawide early Saturday before a drier airmass begins to filter southward behind the front. Greatest rain chances Saturday are forecast south of Orlando and the Cape (50-70%)
with earlier advection of drier air keeping isolated to scattered coverage across northern areas. Deeper moisture may linger in vicinity of the Treasure Coast and Okeechobee county into early next week as the front stalls. This should keep the greatest chances for scattered to locally numerous showers and a few storms across the south, but moist onshore flow should still allow for rounds of onshore moving showers along much of the coast and through the I-95 corridor into next week. Persistent bands of showers and any storms could lead to locally heavy to excessive rainfall, producing flooding issues, mostly across the Treasure Coast. A Marginal Risk for excessive rainfall (Level 1 of 4) exists across this portion of east central Florida this weekend.

A cooler airmass spreads east central Florida this weekend with highs ranging the the mid 70s to low 80s by Sunday. Some gradual warming is then forecast through the middle of next week, but temperatures mostly in the 80s remain near to below normal.

MARINE
Issued at 240 PM EDT Thu Oct 15 2026

Current-Friday (modified previous)...Favorable boating conditions persist through Friday. High pressure north of the area shifts east through late week, as a cold front moves into the Southeast United States. This will allow onshore winds to continue but weaken, with easterly winds up to 10-15 knots diminishing to 5-10 knots tomorrow.
Seas will remain around 2-3 feet. Isolated to scattered showers will be possible across the waters as will a few storms, mainly south of the Cape through tonight. Coverage of this activity increases across the entire coastal waters into Friday.

Saturday-Tuesday (previous)...Hazardous to dangerous boating conditions are then forecast to rapidly develop behind a passing front into the weekend. N/NE winds increase to 20-30 knots across the waters Saturday and then strengthen to around 25-30 knots across the entire waters on Sunday, with frequent gusts to gale force likely. Winds of this intensity are then expected to continue through early next week keeping dangerous boating conditions in place. These stronger winds will quickly build seas up to 10-14 feet by Saturday night and remain around that height through early next week.

Scattered to numerous showers and isolated to scattered storms will also persist across the waters, with this activity continuing to push toward the coast and onshore, especially south of the Cape.

AVIATION
(00Z TAFs)
Issued at 700 PM EDT Thu Oct 15 2026

Light, isolated onshore-moving showers are anticipated to continue across the Treasure Coast terminals overnight, with a mention of VCSH from VRB southward. Mostly dry elsewhere, with light ESE winds at the terminals overnight. Friday, winds become more variable across the interior while the ECSB causes winds to remain out of the ESE. Increasing chances for VCSH and VCTS at the coastal terminals after 17Z, expanding towards the interior terminals after 18Z. Still too early to determine the need for TEMPOs or PROB30s, but this will continue to be closely assessed.
Activity is anticipated to diminish into the evening hours as showers and storms push offshore tomorrow.
