Savusavu tide times

Savusavu sits at the head of a deep, sheltered bay on the south coast of Vanua Levu, Fiji's second-largest island. The bay is approximately 8 kilometres long and 3 kilometres wide, oriented roughly east-west, with the town on the northern shore and a backdrop of forested hills rising to 300 metres. The configuration creates one of the better natural harbours in northern Fiji — protected from the southeast trade wind swell by the island mass, with enough depth (10 to 15 metres through the main channel) to accommodate cruising yachts drawing up to 3 metres. The international cruising community has used Savusavu as a waypoint on the South Pacific circuit — the route between New Zealand, Tonga, and Vanuatu — for decades, and the waterfront caters accordingly: a marina, chandlery, fuel dock, provisioning shops, and a customs and immigration office.

The tidal regime at Savusavu is mixed semidiurnal, with a spring range of approximately 1.0 to 1.4 metres. Fiji's tidal regime has a pronounced diurnal inequality — the two daily high waters and two daily low waters differ substantially in height — and this inequality is most pronounced in the northern islands, which are further from the equatorial node than the main island of Viti Levu. On some days in the cycle, one of the two daily highs is so much smaller than the other that the tidal pattern effectively becomes diurnal — one dominant high and one dominant low per day. For the shellfish and reef-flat harvesters in the villages along the bay shore, identifying the day's lowest low water is the relevant prediction, and this requires the full tidal table rather than a simplified high/low summary.

The hot springs in and around Savusavu harbour are the town's most discussed curiosity. Bubbling spots visible near the shoreline and in the harbour shallows indicate hydrothermal activity beneath the bay floor — warm to hot water (50 to 90 degrees Celsius at the vent) emerging from fractures in the volcanic rock. Locals have historically used the hottest vents to cook food directly — wrapping taro or green bananas in banana leaf and submerging the bundle in the vent. The springs do not significantly warm the harbour water overall (the bay volume is too large), but local temperature anomalies of 3 to 5 degrees Celsius above ambient have been measured at individual vent sites.

The bay's inner flats, exposed at low water springs, are a traditional fishing ground for the Savusavu community. Clams, sea cucumbers, and reef fish are harvested on the tidal flat under customary fishing rights (qoliqoli) managed by the local landowning clan. Visitors should be aware that reef fishing without the express permission of the qoliqoli holder is illegal under Fijian law. The Friday market in Savusavu town has fresh produce and seafood from the local community.

For kayakers and small-boat operators, the bay offers protected flat-water paddling at all tide states. The mangroveed creek mouths on the southern shore are accessible by kayak on the rising tide — the creeks become too shallow to navigate on the ebb. The bay exit to the southeast leads into the broader Koro Sea and is suitable for experienced sea kayakers.

Diving in the offshore waters around Vanua Levu, including the Namena Marine Reserve 25 kilometres south, requires a day boat from Savusavu. The Namena barrier reef has wall diving, current-driven soft coral, and aggregations of reef shark that have been documented in scientific surveys. The boat journey (45 minutes to 1 hour) passes through the Koro Sea, which can be rough in strong trade wind conditions.

Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge. The local tide authority is the Fiji Meteorological Service, which publishes tidal predictions for Fiji reference stations.
