Current Coastal Rating

Fair · 56

Beta

Conditions are fair, but confidence is reduced because some coastal inputs are partial or prediction-based.

Scores are model-specific and are not directly comparable across water types.

Should I Go?

Trip conditions only. Target-species activity and seasonal fishery patterns are not yet included.

Consider

Trip conditions may be workable, but important cautions or data limitations remain.

Medium confidence The recommendation is usable, but one or more inputs are regional, proxied, stale, or incomplete.

Evaluates trip conditions using weather, tides, currents, waves, daylight, and active alerts.

Fishery Profile

Fishery Overview

Cruz Bay VINP harbor, reef, and flats overlay fishery

A Cruz Bay, St. John harbor, reef, and flats-overlay fishery. Yellowtail, barracuda, tarpon, bonefish, and permit use VINP waters around the island hub. This is not Coral Bay, not Lameshur as a destination pin, and not a Puerto Rico paste.

Fishery type
  • Harbor
  • Reef
  • Flats
Fishing modes
  • Inshore boat
  • Shore

Cruz Bay harbor edges · VINP reef around St. John · Protected flats overlay; Lameshur is a tide source, not this pin

Fishery Targets

Yellowtail snapper and barracuda are year-round. Bonefish, permit, and tarpon are flats/harbor overlays without invented exact month cards. VINP and federal closures are legal, not biological season cards.

Access, Safety and Regulations

Access

Cruz Bay is the St. John hub. Virgin Islands National Park fishing rules apply in park waters. A USVI recreational license is administered through GoOutdoorsUSVI. Confirm current DPNR, VINP, and federal Caribbean rules. Do not claim no license is required.

Primary hazards

Coral, heat, and thunderstorms. Missing waves are not calm.

Fishery considerations

  • Tide is nearby Lameshur Bay 9751381 observation and prediction. Lameshur is not Cruz Bay harbor. Current is unsupported and is not inferred from tide.
  • NWS point forecast is required for scoring. 9751381 wind is nearby contextual observation.

Regulations

Size limits, seasons, and possession rules change. Verify the current official regulations before fishing.

Planning limitation

Coastal conditions can vary over short distances. Predictions and remote observations are planning information, not guarantees of access or safety.

  • Pin is Cruz Bay, St. John. Lameshur Bay NOAA 9751381 is NEARBY_REPRESENTATIVE, not Cruz Bay harbor itself.
  • Do not prefer pred-only NOAA 9751309 Leinster Point over live Lameshur observation evidence.
  • Do not fall back to Puerto Rico buoys 41053, 41056, 41115, or 42085.
  • Current axis is UNSUPPORTED. Missing current is not slack or zero. Do not infer current from tide.
  • Virgin Islands National Park gear and access rules are legal overlays, not biological season cards.
  • Customer Current Coastal Rating publishes only when CARIBBEAN_US_VIRGIN_ISLANDS_COASTAL_RATING_BETA_ENABLED is true. Then it is PUBLIC_BETA_CALIBRATING and capped at Consider. Default-off remains fail-closed unavailable. CARIBBEAN_US_VIRGIN_ISLANDS_V1 is a candidate only. PATH1 remains unauthorized. Coastal Estimated is unauthorized.
