G'Day, Carol! :-)

Putting extra layers *under* a snug fitting wet-suit may not be possible
without affecting breathing - particularly if the suit is then tight across
the diaphragm.  Not a good thing when breath-hold diving from the surface
with a snorkel!  Wooly jumpers worn on the outside, however, may give a
degree of additional comfort???

Although one of the first to admit to enjoying the warm, pleasant glow of a
whizz in a wet-suit after lots of coffee, it is a short-lived sensation
and - as it cools - stimulates the kidneys and starts a vicious cycle of,
pee-warm-cold; pee-warm-cold; pee- ....!  And even when snorkelling,
dehydration ain't a good thing!  :-)

Because perhaps the major source of loss of body heat occurrs through the
head - where the blood is closest to the surface - a good, thick, hood
that's not too tight around the neck may be the way to go?

But in those temperatures, rather you than me!  :-)
