Seasonal pattern, where the water is warmer and where to see current temperatures.

Answered at: Checked at:

Short answer

Surface water in Swedish seas ranges from just below freezing to about 25 degrees over the year, according to SMHI, so the temperature in Stockholm depends on the season. SMHI gives no figure for Stockholm itself, and current temperatures at Stockholm's bathing sites are listed by the Swedish Agency for Marine and Water Management.

Why

  1. SMHI says the temperature of the surface water varies with the seasons from just below zero up to 25 degrees.
  2. According to SMHI, summer surface temperature is around 20 degrees in the south and cooler in the north, while in winter it is near freezing in the north and east.
  3. SMHI says the temperature inside the skerries and along shallow shores is usually higher than further out at sea.

Details

The Swedish Agency for Marine and Water Management (HaV) lists 45 registered bathing sites in Stockholm municipality and links to the current bathing temperature in the Stockholm archipelago and the Baltic Sea. For coastal sites there may be forecasts from Copernicus, updated daily around midnight and covering sea bathing sites only.

Tip

Open HaV's page for the bathing site you plan to visit to see the latest information, and remember that sheltered, shallow water is usually warmer than the open sea.

What may differ

The temperature depends on the season and the spot. HaV's current-temperature link covers the archipelago and the Baltic, so it may not include lake sites such as those in Mälaren.
