I NEVER heard of sharks on the Cape ... ever.
We'd visit Manomet almost every year for a week to vacay with neighbors.
It MIGHT be water temp.
Manomet is ice water .... even in August.
I’m in my 50’s and I have to say seals were never around Cape Cod in my youth...ever.
Times have changed. Commercial fisherman have died off and no longer shoot seals.
The Great Whites and seals are mostly on the south side of the cape. That water is warmed by the gulf stream as always.
It’s the over-fishing of their main food source.
They are coming in closer to shore because they have no great schools of fish to consume..............
Water temp is not a factor for white sharks. They have a very wide range from the 40s up to 80 deg, which is more of a range than most shark species.
The Feds protecting both the whites and their preferred meal the seals has caused this problem.

We had the odd shark move up into Maine waters from time to time- and this was 30+ years ago- and the water in boston is warmer than in Maine- Maine water is very painfully cold-
