Actually, it's one of the 5 highest tides of the year at Newquay,
putting it in the top 1% of tides this year. You have to wait until
October for a tide as high as Monday morning's to occur again.
For Portsmouth *there are 105 predicted tides of 4.7m or higher in 2008,
Monday is predicted as 4.7m.
About 710 tides in the year, so I make it about 15 percent.
I can't believe that Newquay is that much different in that aspect of the
I've doubled checked with another set of tidetables, which makes it
the 3rd highest of the year, Newlyn virtually the same. I've also
checked easytide online, which gives 7.3m for Newquay Monday. The
highest for the year is normally about 7.4.
Southampton is a a very abnormal position.
It's not that abnormal tides-wise, apart from the extended high tide
followed by a rapid drop to low water. I live near the mouth of
Southampton Water and at Calshot (on the opposite side from me) high
tide is predicted as 4.8m - one of only 3 in the year (the other two
are in April) so that's in the top half of one percent for the year.
Low tide is predicted as 0.4m and that's one of only 5 in the year
(the other 4 are in April) so that's under the 1% too.
I'm interested in exploring rarely exposed sand and shingle banks at
such times, especially when pressure is high (pity about the
developing low!) but I'm there at high tide too, often trying to
resist getting blown over.
