Putting the water temperature in context

What is normal over the year

In high summer (July/August) the Bay of Lübeck usually reaches 18 to 22 °C, occasionally more in warm spells. Spring is cool (May often 10–14 °C); in autumn the water holds its warmth longer than the air. In winter it drops towards freezing; iced-over bays are rare but possible.

Why the value swings

On the Baltic, offshore wind turns the water over: with strong west/south-west wind the warm surface water is pushed away and colder water rises – the temperature can drop several degrees within a day. After calm sunny days it climbs back just as quickly.

Measured, not “live”

The value above is a model/forecast reading from the marine API for the bay, not a sensor at the jetty. It is good for the trend and for planning your day – the last degree is decided by the thermometer on the beach. There is no official live measuring station for water temperature on Travemünde’s beach.

Part of the context is the water itself: why the Baltic is only about half as salty as the North Sea has its own page.

Frequently asked questions about the water temperature

How warm is the water in Travemünde today?

Currently around 20.8 °C (Open-Meteo Marine, loaded at build time, with a timestamp at the top of the page). In high summer the Bay of Lübeck usually reaches 18 to 22 °C.

When is the water in Travemünde warmest?

Usually in July and August. The Baltic lags the air a little: the warmest beach month is often August, and even September is usually more pleasant than June.

Why did the water suddenly get colder?

Usually because of offshore wind. Strong west or south-west wind pushes the warm surface water away from the coast and cooler deep water rises (upwelling). The temperature can drop several degrees within a day and rise again after calm weather.

Is the water temperature here a live measurement?

It is a measured forecast value from the Open-Meteo marine API for the Bay of Lübeck, loaded at build time and timestamped – not a sensor on the beach itself. There is no official live station for water temperature in Travemünde.

How good is the water quality in Travemünde?

Both official bathing waters – Kurstrand and Priwall – carry the EU classification “excellent” (period 2022–2025). It is based on official laboratory samples taken roughly monthly in season; there is no live reading for quality.

Are there tides in Travemünde?

Hardly – the Baltic is almost tide-free; the tidal range in the Bay of Lübeck is a few centimetres. Noticeable water level changes are usually caused by wind; the live module above shows the current level.
