Hello again,

Great to see many of you at the Boat Show earlier in the week, and thanks for such positive SWIS feedback. Please remember to tell your friends about the site and tell them to go to www.sailingweather.co.uk for their forecasts.

For those who may be travelling further afield this winter I have just released a new section of the SWIS website which contains 5-day synoptic and wind charts for the route from Spain/Portugal to the Canaries/Madeira. To view them go to the SWIS site at http://www.sailingweather.co.uk

If you want to know more about the weather and how it works, why not take a look at my books and DVD. You can see sample pages and watch videos online at http://www.weatherweb.net/books.htm Or, if you fancy an enjoyable day immersed in the world of sailing weather, then why not come along to Weather School on 30th October? I have 4-places remaining on this course and it would be good to see you there. For more information see www.weatherschool.co.uk

Onto the weekend forecast, and if you know anyone who’d like to receive this email each week just tell them to send a request to join to

Have a good weekend,

Issued: 1700 Wednesday 15th September 2010

An area of low pressure is going to be west of Scotland at midday on Saturday, drifting eastwards. Fronts associated with the low will be moving into northern and western parts of the country as a ridge of high pressure to the south recedes into the continent..
Saturday morning begins largely fair across England and Wales, although there will be some morning mist patches in the south and east. These clearing to leave sunny spells, light winds and good visibility.
A different story further north and west where cloud will be bringing some outbreaks of rain, this most persistent across the northern half of Ireland and northwest England. Southwest Scotland having some rain and cloud too. The trough to the far northeast of Scotland bringing the threat of rain or more persistent showers here.
Into the afternoon and the rain will be affecting much of northern England, southern Scotland and Wales. Here visibility will be moderate or poor and there will be fog on the hills. Most of eastern and southern England should be drier and brighter with some sunny spells here.
Winds will be mainly SW 7-12kt (F3-F4) through southern England and Wales, although there will be some NE’ly in it at first in the far south. Turning rather cyclonic as you head north and get closer to the low, but always around 8-12kt (F3-F4).


A cold front clears through the Midlands, East Anglia and then southeast England through Saturday night and into Sunday. A weak ridge of high pressure then follows from the west, ahead of an occluded front into the west of Scotland.
There will be some rain in the morning associated with the front over the southeast and central parts of the country. Most of the rain should be light although an odd moderate burst cannot be ruled out. This will be clearing, taking moderate visibility with it, and then broken cloud follows to much of the country. Expect a scattering of showers in the afternoon, but for many it should be dry.
Some thicker cloud in western Scotland where the occluded front is, this bringing some spots of rain to the west. Ireland willhave a scattering of showers through the day.
Winds will be mainly W-SW 6-10kt (F3-F4) but always a fair amount of variability in them wherever you are in the country.
