West Bay, Roatan tide times

West Bay sits at the southwest tip of Roatan, the largest of Honduras’s Bay Islands, where the barrier reef swings closest to shore and the beach is as close to the Caribbean postcard ideal as this island gets. The sand is fine white coral, the water grades from pale turquoise inshore to deep blue at the reef line, and the reef crest is no more than 80–150 m from the beach at low water. This proximity is the defining fact for every activity here.

The tidal regime is microtidal — spring range 0.3–0.5 m above Chart Datum, mixed semidiurnal pattern with two highs and two lows per day, the two highs commonly differing by 5–10 cm. Neap range narrows to 0.1–0.2 m. In practical terms, the tide is a secondary variable at West Bay: the reef is accessible at all tidal stages, and the beach width changes by 8–12 m over a full spring cycle — noticeable but never limiting.

What the tide does control is passage depth between the reef crest and the shore. The inner lagoon averages 0.5–1.2 m at mid-tide. On a spring low, that depth drops to 0.2–0.7 m — thin enough that kayaks and stand-up paddleboards graze the bottom in places and small motorized pangas need to take care on the entry line through the reef pass. On the flood, the passage fills and small-boat transit becomes straightforward. Dive boats and glass-bottom boats use the deeper western pass regardless of tidal state, but the direct, shorter entry through the inner reef is tide-dependent.

For snorkellers, the reef crest at West Bay is one of the most accessible in the Bay Islands group. At high water, even novice swimmers can float over the shallowest sections with 0.6–1.0 m of clearance above the coral heads. The inner side of the reef has buttress formations, sea fans, and a resident population of parrotfish, queen angelfish, and yellowtail snapper. The east-to-west flood current along the reef runs 0.3–0.5 knots on spring tides — enough to carry a snorkeller 100–150 m down the reef in 30 minutes without effort. Dive boats deploy from the beach into 2–5 m of water on the inland side of the reef for pre-dive kitting, then cross the crest into deeper water on the seaward face.

For beach families, West Bay works well on any tide. The inner lagoon stays shallow and calm regardless — the reef absorbs swell energy before it reaches the beach. The water temperature is 27–29 °C year-round. Morning visits (before 10:00) avoid the worst of the midday heat and the tour-boat crowds arriving from Coxen Hole and the cruise ships when a vessel is in port at Mahogany Bay; the beach transitions from quiet to busy between 09:30 and 11:00 on ship days.

Photographers get the best light at West Bay before 09:00 and after 16:30. The beach faces roughly south-southwest, so direct morning light hits the reef from the east; the lagoon reflections are sharpest in the early-low-water window. Late afternoon low water — common in some lunar cycle periods — exposes sand flats between the beach and the reef crest that produce excellent foreground texture for wide-angle shots. The reef’s colour in the upper metre is best shot when the sun is above 30° elevation and the surface is calm.

Sport fishing from West Bay focuses on the reef edge and the drop-off beyond. Mutton snapper and grouper hold on the reef structure at all tides; the drop-off on the seaward face of the reef, where the bottom falls from 5 m to 15 m in 50 horizontal metres, concentrates jack and barracuda on the ebb as water drains from the lagoon. Charter pangas operate from the beach; the 20-minute run to the east end of the island reaches deeper water for pelagic species.

All tide predictions for West Bay come from the Open-Meteo Marine gridded model. Timing accuracy is ±45 minutes; height accuracy is ±0.3 m above Chart Datum. For the small tidal range here, the height uncertainty is a significant fraction of the signal — treat the predictions as orientation data rather than precision timing.
