Swimming in the sea here on the south coast of Devon yesterday under endless
blue sky and hot sun, it seems that the sea has warmed considerably over the
last week or so and the pool of cooler water which was hogging the coastline
from Dartmouth to the Isle of Wight has vanished being replaced by sea temps
at least a couple of degrees warmer.

Regarding that pool of cooler water (~16C), is that normal or just
symptomatic of the summer that we have had so far, i.e., does it occur every
year; anyone cast light on the matter?

Indeed, the sea seems warmer now than anything I have experienced since
swimming in the Aegean in August a couple of years back.
