Daily ocean conditions for anyone on the water, Space Coast to Key Largo

Issue #17

⚠️ Strong Shower Warning — Atlantic waters Jupiter Inlet to Ocean Reef, shore to 60 nm. Shower with 30-knot winds and possible waterspouts located 13 nm east of Pompano Beach, moving west at 15 knots. Boaters offshore should seek safe harbor immediately.

Seas remain moderate across South Florida this morning with a squall moving into Atlantic waters offshore. Space Coast buoy 41009 (20 nm offshore) reads 4.6 ft at 8-second period — clean swell energy. Treasure Coast and Gold Coast buoys show 4.6 ft and 3.9 ft respectively, both with 5-second periods — shorter wind chop. Upper Keys are calm at 2.6 ft. Water temps uniform: 76–77°F across all regions.

NWS zone AMZ630 issued a strong shower warning this morning for coastal and offshore Atlantic waters from Jupiter Inlet to Ocean Reef, shore to 60 nm. A brief but intense shower capable of 30-knot winds was located 13–14 nm east of Pompano/Lighthouse Point as of 4:09 PM EDT, moving west at 15 knots. Waterspouts are possible. The system is expected to pass quickly — inshore and Gulf-side remain unaffected.

Narcosis Dive (West Palm Beach) confirmed excellent conditions April 1 — 50–60 ft visibility, 77°F, light trickle-north current, hawksbill and green turtles, spotted moray, healthy corals. Rainbow Reef (Key Largo) has not posted a trip report in the last 48 hours. Blue Heron Bridge runs two windows today: morning 8:46–9:46 AM (2.6 ft, good) and evening 9:15–10:15 PM (3.0 ft, fair). East winds at 17.1 kt may add surface turbulence on the evening window.

Waterspout Alert & Offshore Shower Safety A strong shower warning is active in Atlantic waters 20+ nm offshore with potential for waterspouts, 30-knot winds, and lightning. If boating offshore, monitor constantly and seek safe harbor if conditions deteriorate or a waterspout is spotted. Even brief squalls create dangerous wind shear and reduced visibility. Inshore boaters should stay alert for sudden gusts. Verify with your captain or check the Coast Guard forecast before leaving the inlet.
