NOAA SATELLITE DATA (1991–2020 30-YEAR CLIMATOLOGY)

Slovenia Sea Temperature in November

Historical 30-year sea surface temperatures across 4 coastlines in Slovenia for November. Derived from NOAA 0.25° blended satellite and in-situ marine observations.

Climatology Notice: Temperatures represent the 30-year long-term historical average (1991–2020 normal), not a live single-day sensor forecast.

16.2°C

Bracing / Crispaverage across 4 surveyed coastlines in Slovenia, November

Ranges 16.2°C at Fiesa Beach to 16.2°C at Strunjan Beach.
None of Slovenia’s 4 surveyed coastlines reach the 21°C swim threshold in November.
On the national average, the water is above 21°C from 5 Jun to 30 Sep — about 117 days a year.
9.2°C cooler than Slovenia’s August peak of 25.4°C (see August).

The November Thermal Lag Advantage

Because seawater has a high specific heat capacity, it acts as a massive thermal battery. Southern European and Mediterranean basins absorb solar energy all summer, reaching maximum heat storage by late August. In November, while air temperatures drop, the water releases heat slowly, which creates sea temperatures that are typically 3°C to 5°C warmer than in June.
