There's no such thing as bad weather, just the wrong clothing!

We have several popular weather links here for you to choose from and a wind speed conversion table below.

Wind speed conversions

The Beaufort Scale was originally developed in 1805 by Sir Francis Beaufort as a system for estimating wind strengths without the use of instruments. It is currently still in use for this same purpose as well as to tie together various components of weather (wind strength, sea state, observable effects) into a unified picture. The table below provides the Beaufort Scale and conversions to popular units. Following this there is a descriptive chart of the Beaufort Scale.

Beaufort Scale Description

Beaufort ForceDescriptionLand ConditionsSea State
0 Calm Smoke rises vertically Sea like a mirror
1 Very Light Direction of wind shown by smoke drift only Ripples with appearance of scales, no foam crests
2 Light breeze Wind felt on face, leaves rustle, vanes moved by wind Wavelets, small but pronounced. Crests with glassy appearance, but do not break.
3 Gentle breeze Leaves and small twigs in constant motion, wind extends light flag Large wavelets, crests begin to break. Glassy looking foam, occasional white horses.
4 Moderate breeze Raises dust, loose paper, small branches move Small waves becoming longer, frequent white horses.
5 Fresh breeze Small trees in leaf begin to sway Moderate waves of pronounced long form. Many white horses, some spray.
6 Strong breeze Large branches in motion, umbrellas used with difficulty Some large waves, extensive white foam crests, some spray.
7 Near gale Whole trees in motion, inconvenience felt walking against the wind Sea heaped up, white foam from breaking waves blowing in streaks with the wind.
8 Gale Breaks twigs off trees, impedes progress Moderately high and long waves. Crests break into spin drift, blowing foam in well marked streaks.
9 Strong gale Slight structural damage occurs High waves, dense foam streaks in wind, wave crests topple, tumble and roll over. Spray reduces visibility.
10 Storm Trees uprooted, considerable damage occurs Very high waves with long overhanging crests. Dense blowing foam, sea surface appears white. Heavy tumbling of sea, shock-like, poor visibility.
11 Violent storm Widespread damage Exceptionally high waves, sometimes concealing small and medium sized ships. Sea completely covered with long white patches of foam. Edges of wave crests blown into froth. Poor visibility.
12 Hurricane Extreme destruction Air filled with foam and spray, sea white with driving spray, visibility.


Huge Gusts at Kielder

Weather station displaying hurrican conditions

It may not be as windy as it has been before but this is the first time we have recorded Hurricance Force Gusts on the weather staton at the club. On Sunday 23d March 2008 in the wintery conditions we experienced some sudden squalls and strong gusts. On more than one occasion the weather station recorded more than 64 knots (Hurricane force) and on one occassion recorded "HH.HH". We are not sure what that indicated except possibly hurricane force gusts exceeding the station's 5 second sampling rate. A (slightly blurred) picture was taken showing the weather station recording 77+knots of wind at the clubhouse. Good job no one was sailing at the time, the previous race having been abandoned!
