Annual Water Temperature Trend

Langeland, an elongated Danish island in the Region of Southern Denmark, is bordered by sheltered straits and the Baltic Sea, which gives its coastal waters a moderated seasonal rhythm. Water temperatures around the island vary with exposure, depth and wind, but typical seasonal ranges are clear: in winter surface temperatures commonly sit between 2 °C and 6 °C, spring brings a gradual rise to roughly 6 °C–12 °C, summer months generally warm the seas to about 16 °C–22 °C with July and August often at the upper end, and autumn sees a steady cooling from around 14 °C in early September down to 8 °C–12 °C by October and November. Shallow bays and protected inlets tend to warm earlier in the year and retain heat longer into autumn, while open-coast sites stay cooler and are more affected by passing weather systems.
