Local conditions and F10

[jimi]

Pondering over a recent post when oodles of peeps experienced some very different conditions within 2 or 3 miles of each other and knowing most of them personally I'd hesitate to call 'em liars but the shout of "well Bramblemet only showed F6 ergo everywhere in the Solent is F6" does actually display a lack of knowledege of local weather effects ie .. never mind convergence, divergence, funneling, acceleration zones or even the thermal effects of big clouds .. so hands up .. how many of us really understand the local effects in our own waters?

Er me.
Definitely.
Malin Head = F5 min wind against tide

good call.
Same area of coastline 4 miles long,south facing, (uk) first mile is undulating golden fields behind grazing land gently reaching the beach, low slow incline inland. second mile & half the fields are freshly ploughed and very dark in colour and same gentle foreshore, last section the govt installed a nuke power plant - big chimneys etc.
now burning hot sunny day, onshore noon breeze kickin in (s.w.) f2 as you begin passin this area heading east, the tide is just on the ebb and slowly making west...................

You complete

A good point Jimi. Have you ever noticed the difference between the Eastern and Western Solent? Often when I get to Egypt point going either way the wind backs/veers, and a F6 at Gilkicker can be a flat calm at Yarmouth or vice versa.... Of course it could well be the fact that it takes a couple of hours to get there but I don't think so.....

I can do it in well under half an hour, but yes, very different conditions can be evident over quite different areas of the Solent in the same time span

Re: Tide is probably biggest factor

In areas of strong tides the tidal effect is probably the biggest factor. Also the unwary running off down channel with20 knot wind a nd 4knot tide with them may get quite a hammering beating back after the tide has changed.

Along the coast between Porlock and Ilfracombe there is some high ground(not cliffs but steep) sloping steeply down to the shoreline. Anyone trying to enjoy a lee there in strong Southerlies may get a shock by the sometimes savage down draughts that occur without warning. In a force 5 they have been known to knock a heavy yacht flat for a minute before calm is restored.

Acceleration of wind around headlands especially if opposing the also accelerated tidal stream.

Sea and land breezes ,I am sure the list is endless I doubt if anyone fully understands all local effects.

Us yesterday (Easter Saturday) enjoying sunshine and sailing breeze(thats me with the hat),apparently the Humber experienced fog...
