Very big spring tides the last couple of days, size decreasing now.
Luckily it's not been rough, and the pressure's been reasonably high.
Still not a good idea to park on the Abbey Slip though.

Pleasant enough day yesterday, spells of hazy sunshine raised the
temperature to 15.1C. Might top 16C today, but damp drizzly & misty.
It looks like the temperature will stick near 15C much of the evening
& night. Swell's picked up markedly though www.sennen-cove.com/todaysurf.htm
- makes quite a change.

[OT] but I find this a vaguely depressing time of year. Virtually all
the small boats are out of Penzance harbour & in the harbour car/boat
park now. The baulks go down in the harbour mouth at Mousehole
tomorrow, to stop storm waves surging into the village over the
winter. Although the waves do a pretty goood job at taking the direct
route sometimes. www.easterling.freeserve.co.uk/PzStorm.PDF

Time to get on with all the decorating & maintenance jobs.

We've been in the clouds all day up here in Stithians - 120 metres a.s.l.
Visibility been down to about 100 metres at times with drizzle, mist and
fog.

Graham, I was wondering, are these high tides higher and more regular
nowadays, or just a normal occurance?

Keith,

The largest astronomical tides occur close to the equinox. The highest
predicted tides in Penzance this year being 20/21st March, 28th
September & 26th October.

However, reality often varies quite a bit from predictions, even under
quite benign weather conditions. I've seen the tide still rising 30 or
40 minutes after it was due to turn.

The lower the atmospheric pressure the higher the tide, also,
especially in a bay like Mount's Bay, an onshore wind can raise the
tide. This combined with low pressure, can increase the height of the
tide by a few feet. On top of this you have the wave height to
consider. So what can make a difference is if there has been an
increase in stormy conditions close to the equinox, and I don't really
think there has.

I guess what I was thinking on top of this is are sea levels higher in
general nowadays so spring tides more dangerously high?

Well, Cornwall is actually sinking, and Scilly is sinking quite
steadily. So this does make a rise in sea level more significant.
Flying into Scilly you can see the old field hedges (walls) under the
sea between the Islands. It's certainly giving a few problems at Hugh
Town, where a storm a few years back came disturbingly close to
eroding through the bank between the south facing Porthcressa beach,
and breaking right through to the north facing Town (harbour) beach.

Hi Graham

I thought that it was only the south east of England that was still sinking
and the west of the UK was rising, caused by 'rebound' after the removal of
the weight of glaciers from the last ice-age.

Nick,

Scilly is certainly sinking. I'll try to dig out some info I've got on
it & email it to you.

I would have thought any ice age rebound would have been lower in the
far SW than anywhere else?

I was reading a review of the Birds of Essex and apparently the book
highlights the great loss of saltmarsh in Essex in recent times which is
presumably due to a rise in sea levels. Presumably this is mainly due to
rising sea levels.

Still searching, I've recently moved & still don't know where
everything is. However, 3000 years ago Bryher, Samson, Tresco & St.
Martins were all one island. It is just possible to walk from Tresco
to both St. Martin's & Bryher a handful of days a year at low water
spring tide. (When I say walk, you still have to wade through area
2-3' deep.) As this is only possible by following sand bars, and the
old field boundaries are largely hidden below them, and Spring tides
on Scilly are around 19' the sea must have risen 30' in the last
3000 years, and possibly as much as 50'.
