The October 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 October, 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.
