Rubber Duck and the A01 Buoy both say it’s time to go for a swim!
The 80.1 F is just the seaweed warming up at low tide but that 53.8 F is a sensor three feet down and it’s real. Just Google “A01 Buoy” which is a couple miles off Gloucester Harbor and you get the exact same temp.
What’s it all mean? It means it’s time to go for a swim! It’s time to toss a few poppers because Mrs Striped Bass has arrived. She waits until it is 50 F. What are you waiting for?
