Marine weather in Estonia – wave height, wind and sea water temperature today
Marine weather in Estonia today
Marine weather in Estonia today gives an up-to-date overview of conditions in the Baltic Sea and Estonian coastal areas. Here you will find information on wind speed and direction, wave height, sea water temperature and sea level. Marine weather often differs from inland weather, as the Baltic Sea strongly affects coastal temperatures and wind conditions.
If you are searching for "marine weather today", "wave height", "sea water temperature" or "wind at sea", this page brings together all the information you need.
Wind at sea
Wind is the most important component of marine weather. In open sea areas, wind speed can be significantly higher than inland.
Important indicators:
- 🌬 Wind speed (m/s)
- 🧭 Wind direction
- 💨 Gusts
Strong wind directly affects wave height and sea state. In autumn and winter, low-pressure systems can bring storm winds, especially on the west and north coast of Estonia. You can also follow wind data from the wind map.
Wave height and sea state
Wave height depends on wind strength, wind duration and extent of open water. On the open sea, wave height can be significantly greater than in sheltered bays. Conditions may differ, for example, in the Gulf of Riga or along the Gulf of Finland.
Wave height is important for:
- sailors
- fishermen
- surfers – detailed info from the surf page
- small craft
With strong wind, wave height can increase quickly, making movement at sea dangerous.
Sea water temperature
Sea water temperature affects swimming conditions, beach weather, fishing and marine ecosystems. In summer, sea water temperature can rise above +20 °C, especially in shallow, sheltered areas like Pärnu Bay. On the open sea, temperature is usually lower.
In spring the sea warms slowly; in autumn the temperature stays higher than air temperature for longer.
For beach weather and swimming conditions, see the beach weather.
Sea level
Sea level is affected by wind direction and strength, air pressure and general Baltic water level variation. With strong northerly wind, water level can rise, especially on the north coast of Estonia. Low air pressure can also raise water level.
Monitoring sea level is important for:
- ports
- coastal residents
- sailors
With strong wind and low air pressure, water level can fluctuate significantly.
Marine weather by region
Gulf of Finland
In the Gulf of Finland, wind can be strong, especially when low-pressure systems move over Scandinavia. Tallinn and Viimsi coast can experience significant gusts.
West Estonia coast and islands
Around Saaremaa and Hiiumaa the sea is more open, meaning wind and wave height can be greater than in mainland bays.
Gulf of Riga
The Gulf of Riga is partly sheltered, but strong wind can still produce high waves. Pärnu coast conditions can differ from mainland inland weather.
Marine weather and surf
Surf conditions depend directly on wind direction, wave height and wave period. For detailed surf forecast, see the /surf/page, which focuses on surf enthusiasts and real-time coastal station data.
Marine weather vs beach weather – what is the difference?
Marine weather focuses on wind at sea, wave height, sea level and the broader marine environment. It is information for sailors, fishermen and everyone working with the sea.
Beach weather focuses on swimming conditions, water temperature on beaches and wind on the coast. It is information for beach visitors and swimmers.
Full beach weather overview see beach weather.
How does marine weather affect Estonian climate?
The Baltic Sea significantly affects Estonian weather:
- In winter the sea keeps coastal areas slightly warmer.
- In spring the sea slows air warming.
- In summer the sea balances heat waves.
- In autumn the sea stays warm longer.
This marine effect makes Estonian climate more moderate compared to inland climate.
Marine safety
Before going to sea, always check wind speed and direction, wave height, warnings and water level.
With strong wind and high waves, going to sea in small craft can be dangerous.
