This natural shelter helps create generally calm sea conditions and slightly warmer surface waters during settled weather.

During autumn, the sea often remains around 18–20°C before gradually cooling. Winter temperatures usually sit between 14°C and 16°C, while spring brings a steady rise from roughly 15°C towards 18°C as air temperatures increase and the days become longer.
