Marine Weather and Tide Forecast for Micco, FL

DISCUSSION
Issued at 315 AM EDT Fri Apr 17 2026

Today-Sunday...The advertised warming trend heats up today as high pressure continues to build over the Florida Peninsula this weekend.
Temperatures in the 60s to around 70 degrees this morning set the stage for an efficient warmup into the 80s, nearing 90 degrees in several spots this afternoon. GOES-derived PW indicates really dry air anchored over our area, but some 1"+ values are starting to approach the Treasure Coast. Here, a scattered layer of stratocumulus is streaming northwestward and producing light showers (south of Martin County, for now). The forecast, reflecting recent hi-res guidance, carries a 15-20% chance of showers through midday from Vero Beach southward. Elsewhere, dry and mostly sunny conditions will persist as the east coast breeze develops and moves inland. Tonight, lows settle into the 60s to low 70s areawide with no rain forecast.

H85 temps warm a bit more Saturday and Sunday, solidifying a medium to high chance (50-80%+ NBM prob.) of locations near/west of I-95 reaching the 90-degree mark. There will be a few more clouds Saturday and especially Sunday as the upper column and 850-750mb layer moistens. Model soundings still show a stout dry layer between 700-400mb, working to suppress any precip chances. The east coast breeze should keep highs a few degrees cooler on Saturday, but perhaps less so on Sunday as light westerlies delay the formation of the breeze later into the day. For those spending time outdoors, especially individuals sensitive to warmer temperatures (low 90s), be sure to take breaks in a cool space and stay adequately hydrated.
At area beaches, at least a moderate risk of rip currents is forecast to continue. Swim near a lifeguard and never enter the water alone!

Sunday Night-Thursday...High pressure quickly weakens Sunday evening ahead of an approaching cold front. Winds start to turn northerly just before or around midnight as this front approaches, and breezy conditions look to develop along the coast through daybreak Monday (gusts 20-25 mph, up to 30 mph in Volusia). Lack of forcing and time of day will limit overall precip coverage through sunrise, but with increasing PW along the front on Monday, a 25-40% rain chance is introduced from Cape Canaveral southward. Even across the south where chances are maximized, light QPF is anticipated (generally 0.10" or less). Conditions will be breezy to gusty in the wake of the front on Monday and even into Tuesday. Hazardous beach conditions are likely to start the week as a result, including an increased risk for life-threatening rip currents.

Drier conditions return Tuesday, as high pressure centered over the Mid Atlantic expands south and west. An onshore breeze continues mid to late week, and some guidance tries to indicate embedded light showers forming in the easterly flow. With low confidence and lack of model-to-model consistencies, rain chances generally remain 15% or less at the coast Wed-Fri. Temperatures cool noticeably for the first half of the week, remaining slightly below normal. By mid to late week, though, temps bounce back closer to normal (upper 70s to mid 80s).

MARINE
Issued at 315 AM EDT Fri Apr 17 2026

Favorable boating conditions are forecast through Sunday afternoon with high pressure established over the local waters. Light southerly flow this morning veers easterly late this afternoon, 8-12 kt, behind the developing sea breeze. SSE winds linger overnight and into Saturday, reaching 10-14 kt and veering SSW late Saturday night. This light offshore wind backs SSE Sunday afternoon, just ahead of an approaching cold front arriving Sunday night. A 2-3 ft swell is forecast to persist through Sunday with only a low chance of isolated showers through midday today, mainly south of Sebastian Inlet.

Sunday night into Monday, a cold front is forecast to move south across the waters. Quickly deteriorating conditions result as NNE winds increase 20-30 kt with occasional gusts near or just below gale-force. Seas respond by building rapidly to 7-11 ft Monday and Monday night. Boating conditions gradually improve north to south late Tuesday into Wednesday but may remain poor overall. Small Craft Advisories will be needed beginning Sunday night. Scattered showers and even an isolated lightning storm are possible along/behind the front late Sunday night through Monday.

AVIATION
(06Z TAFs)
Issued at 125 AM EDT Fri Apr 17 2026

Light and variable winds persist at the terminals early this morning along with mostly clear skies. While there continues to be some model guidance hinting at a low chance for some patchy fog development, confidence is not high enough in this to include within the forecast. Winds pick up to around 10 knots out of the east after 16Z along the coast and after 19Z across the interior, becoming light and variable once more late tonight. Mostly dry conditions are forecast near the terminals, though there is a low chance for isolated showers near SUA and possible FPR. Did not include any mention of this within the forecast package, but will monitor and amend as necessary.

FIRE WEATHER
Issued at 315 AM EDT Fri Apr 17 2026

A dry airmass and high pressure will continue to support lower humidity over interior east-central Florida today and Saturday.
Light and variable winds overnight and each morning turn onshore during the day, reaching 10 to 15 mph. Occasional gusts around 20 mph are possible, particularly at the coast as the sea breeze develops and moves inland. By and large, fire sensitive conditions are anticipated. Additionally, an isolated shower or two is possible through midday along the Treasure Coast.
