Banyuwangi tide times

The Bali Strait narrows to 2.4 km between Ketapang (Banyuwangi) and Gilimanuk (Bali). Tidal currents run 2–3 knots through the strait, reversing direction with each tidal cycle. The current is strongest around mid-tide (peak ebb and peak flood) and approaches slack near high and low water. The ro-ro ferry crossing operates around the clock regardless of current state, but crossing times extend at peak flow. Sailors in smaller vessels should plan to cross near slack water.

BMKG data for Banyuwangi records a mean tidal range of approximately 1.5–2.0 m above Chart Datum, with mixed semidiurnal character. The tidal signal here is driven by the Indian Ocean rather than the Java Sea, so it differs from stations on Java's north coast. Spring tides push the range toward the upper end; neap tides reduce it. The diurnal inequality means the two daily high waters are often different in height.

Yes — Banyuwangi is the standard staging town for the Ijen trek. The crater rim is 50 km northwest of the city centre; most operators run minibus transfers departing around midnight to reach the trailhead by 01:00–02:00, targeting the crater rim at pre-dawn. The blue-flame sulphur combustion is only visible in darkness; once the sky lightens it becomes invisible. A 2–3 day stay in Banyuwangi allows Ijen plus a day on the coast or a Bali Strait crossing, combining both well.

The closest accessible break with consistent quality is Plengkung (G-Land), approximately 70 km south. It's a world-class left-hand reef break, activated by Indian Ocean south-easterly and east swells, best from May through September. Access is by boat charter from the southern coast near Muncar, or by overland track with a Meru Betiri National Park entry permit. The area is remote — accommodation options at G-Land are basic surf camps. Closer to Banyuwangi, Pulau Merah (Red Island) beach offers a more accessible but less powerful option.

Predictions here are modelled from Open-Meteo Marine global tidal data, with typical accuracy of ±45 minutes on timing and ±0.2–0.3 m on height. For navigation through the Bali Strait, ferry scheduling, and any safety-critical use, consult official BMKG (Badan Meteorologi, Klimatologi, dan Geofisika) tidal predictions at bmkg.go.id. Tidal current predictions for the strait require dedicated current tables — tidal height alone is not sufficient for strait navigation planning.
