Vestmannaeyjar (Westman Islands) tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

Conditions as of 23:00 local time. Refreshes daily.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Atlantic/Reykjavik local. Folk tradition, not a scientific forecast.

Last spring tide on Mon 04 May (range 2.2m). Next neap on Sun 10 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

The Westman Islands are a volcanic archipelago 10 kilometres off Iceland's south coast — fifteen islands and thirty rock stacks rising from the North Atlantic, inhabited on only one (Heimaey) and formed by the same volcanic activity that created Iceland itself. The most recent major event was in 1973 when Eldfell volcano erupted without warning on Heimaey, covering a third of the town in lava and ash in five months. The eruption expanded the island by 2.5 square kilometres. The lava field from that eruption is still warm in places and has been partly excavated to reveal buried houses — the Pompei of the North exhibition runs tours. Tidal range at Vestmannaeyjar is 3.0 to 4.0 metres at springs. The island group's exposed North Atlantic position receives full tidal exchange, and the channels between the islands create strong tidal currents — understanding them matters for any boat trip between the islands. The harbour at Heimaey is protected and functional year-round; the open-ocean crossing from the mainland (by ferry or small plane) is weather-dependent. The puffin colony on the Westman Islands is the largest in the world: approximately 8 to 10 million Atlantic puffins nest in burrows on the cliff tops and grassy slopes between May and August. The density is extraordinary — from the cliff edge at Stórhöfði you can watch puffins landing, taking off, and queuing at burrow entrances continuously. The birds arrive in May, raise one chick, and leave in August. Local children participate in the puffin rescue (Puffin Patrol) — newly fledged birds disorientated by town lights are collected and released at sea. Seakayaking in the island channels is the premium water activity. The rock stacks and sea caves are accessible in calm conditions, and the marine life around the islands is exceptional: harbour seals, grey seals, porpoises, minke whales, and orca are present in the channels. The current patterns between the stacks require experience — local guiding is the correct approach. Rigid inflatable boat (RIB) tours cover more ground more safely for those without kayaking experience. Heimaey town is small (approximately 4,000 people) and functional. The aquarium and natural history museum document the island's marine environment. The Þjóðhátíð festival in the first weekend of August — a national gathering in the natural amphitheatre of Herjólfsdalur valley — draws 15,000+ people, equivalent to three times the island's population, for bonfires, music, and fireworks that can be seen from the mainland. 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.
