Hello again,

Can you believe it is the last Bank Holiday of the summer season? An extra day is tagged onto this forecast covering Monday.

SWIS forecasts will be issued throughout the weekend, and you can view them at www.sailingweather.co.uk. If you can spread the word about these forecasts, and keep your feedback coming, it will help me build a better service. For those of you not covered by SWIS, my apologies, I’m getting to you as fast as I can.

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

I’m also going to try my best to run a weekend forecast Webinar sometime today or this evening, where you can watch me present a live weekend weather forecast and you can join in and ask any questions about the weekend weather.

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

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: 1600 Thursday 26th August 2010

Low pressure to the northeast of Shetland will bring a west to northwest flow to the whole of the country. Troughs will be moving southeast in the flow, mainly affecting Scotland. High pressure remains to the southwest of Ireland, strengthening the west to northwest wind over the British Isles.
It should be a fair day overall for much of southern England and Wales. Good spells of sunshine here and good visibility too. There is a low risk of a shower, especially in more eastern areas.
As you head further north the risk of showers increases. There could be some heavy ones through north Wales and northwest England. Cloudier skies for northern and western Scotland, as well as Northern Ireland where cloud could thicken to give some more persistent outbreaks of rain at times. More eastern parts of Scotland and England also at risk of a heavy shower but tending to miss the worst of them
Winds will be WNW 18-24kt (F5-F6) through Scotland and northern England WNW-NW 14-18kt (F4-F5) for southern parts of England.


A cold front pushes southwards through the northern of England and Northern Ireland toda. As low pressure moves into northern Denmark and the area of high pressure begins to build west of Ireland.
Cloud and showers will merge to more persistent rain along the line of the front as it moves south. Behind it will be broken cloud and some bright or sunny spells, although further showers. Some of these could be heavy on eastern coasts of Scotland and northeast England.
To the south it is going to be remaining breezy and rather cloudy with a scattering of showers, although the threat of these increasing through Wales, the Midlands and East Anglia in the afternoon as the front arrives.
Winds WNW 15-20kt (F5) to the south of the cold front, then becoming NW 18-24kt (F5-F6) behind it, but be prepared for 29-35kt (F7-F8) along eastern coasts of Scotland and northeast England at times, but this increase probably someway behind the front.


The area of high pressure builds to the west of Scotland today as an occluded front scrapes through southeast England, taking outbreaks of rain with it.
Cloud and some showery outbreaks of rain across the southeast of the country at first, this reducing visibility in places. It will be a very windy start to the day here too, with those winds probably not easing until the afternoon.
Showers will be affecting eastern coasts of England and Scotland, most of them fairly well scattered, although there could be an odd heavier one here and there too.
Further west conditions are going to be dry with some good spells of sunshine, the best of them across southwest England.
Winds N-NNW 29-34kt (F7-F8) for parts of East Anglia and southeast England at first (coasts), 22-28kt (F5-F6) inland. Mainly N 10-12kt (F3-F4) in the west of England, Wales and most of Scotland, although NE 4-8kt (F2-F3) for Ireland. NNW 22-28kt (F5-F6) for the coasts of eastern Scotland.
