A lively sea — hard work to swim in; think twice
Porthpean · 0.9 m · 3 ft · wind NE 8 mph
A read on the sea before you head down for a swim: wave size, wind, and sea temperature for the bay's beaches. The numbers come from open-water weather models at the mouth of the bay — St Austell Bay's beaches are sheltered, so what you find on the sand is often calmer than the reading here, especially when the wind is from the south-west.
No lifeguards on these beaches
The family swimming beach, tucked into the west side of the bay — usually calmer than the open-water reading suggests.
