Reykjavík 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 3.0m). Next neap on Sat 09 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.

Reykjavík sits at 64 degrees north on the shore of Faxaflói bay, which opens west toward the North Atlantic. The city is the northernmost capital in the world and runs entirely on geothermal energy — the hot water that heats every building and fills the Laugardalslaug swimming complex flows from the volcanic geology 2 kilometres below the city. The old harbour (Grandi) and the new lighthouse district (Grótta) give two distinct waterfront experiences: the Grandi side is fish factories, whale-watching boats, and craft breweries converted from industrial units; Grótta is a tidal causeway walk to a lighthouse with views of Mount Esja across the bay. Tidal range at Reykjavík is 3.0 to 4.0 metres at springs — the North Atlantic delivers substantial tidal movement into Faxaflói, and the bay geometry amplifies it. Tidal state matters concretely: the Grótta causeway is passable only around low tide; at high tide it disappears under the sea. The tidal flats exposed at low water in the inner bay attract large numbers of Arctic terns, oystercatchers, purple sandpipers, and eider ducks. Spring tides expose a much larger area than neap tides. The sea temperature at Reykjavík reaches 11–12°C at its July–August peak. Wild swimming exists — Nauthólsvík geothermal beach, a small sheltered inlet south of the old airport, has a geothermal pipe warming a section of the bay to 15–20°C, with a changing facility and access to the cold sea alongside. It is a genuine local institution. The Sundhöll Reykjavíkur (indoor pool, 1937) and Laugardalslaug (outdoor, heated, with hot pots) are the mainstream aquatic infrastructure. Whale watching operates from the old harbour year-round, with the highest success rates May through August when minke whales, humpbacks, and occasionally blue whales feed in Faxaflói. The departure point at Ægisgarður in the old harbour district has several competing operators; most trips run 3 hours and cover the feeding grounds 15–25 kilometres offshore. Puffin colonies on the Lundey and Akurey islands in the bay are visible from city shore in nesting season (May–August) and reachable by RIB boat in 15 minutes. The Hallgrímskirkja church tower is the unambiguous orientation point for the city from the water — the stepped basalt-column architecture visible from the bay. The Harpa concert hall (Henning Larsen, 2011), on the harbourfront, serves as the cultural and event anchor. The domestic food supply runs through Kolaportið flea and fish market on weekends in the old harbour building; the restaurant scene clusters around Laugavegur and the food halls that have converted from the fishing industry infrastructure. 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.
