    on the forecasted conditions For example a reasonable swell may be forecast but a strong offshore wind could be flattening the sea state Wind may also either be increased or decreased by local affects not picked up by the forecast model such as sea breezes katabatic winds and venturi affects Forecast time ranges With any forecast as the time increases away from the present the forecast becomes progressively inaccurate As inaccuracies creep in to the generated data models they become more and more exaggerated Therefore as a rule of thumb you should expect that the first 2 3 days of a forecast should be the most accurate according to the day s time frames and details As we move past that the predictions become more of an indication of events than a strict guide Further still near the end of the forecast run the model will be quite experimental Therefore when planning trips using the Beach Search tools bear the above facts in mind and plan for trips no more than 2 3 days in advance Forecast models used by Bigsalty GFS Atmospheric Model The numerical model run by Bigsalty to forecast all atmospheric data is the GFS Global Forecasting System made available by the NOAA This generates data sets of a 0 5 degree resolution covering the entire globe which is equivalent to having forecasted data at points in a grid over the globe with 55km spacing Because we are primarily focused on UK Ireland conditions we subset this data and can interpolate the variables to any given exact location in this region NWW3 Wave Model The model used for Bigsalty s Wave forecast is the NWW3 NOAA s Wave Watch model which covers the majority of the world s oceans It s considered to be one of the

  • Big Salty beach information for windsurfers, kitesurfers and wind sports
    for beginners Note that this is also not forecast related and is based on how a location is expected to perform as a rule of thumb For example a beach rated 5 stars for waves will not be up to much if the forecast isn t cranking Good wind directions This indicates wind directions that the location is known to be sailable in Please note that some beaches in cliff bound regions may be unsailable in certain wind directions and also that a location is not worth windsurfing and not safe to do so in an offshore wind Port starboard tack bias Most locations have a port and starboard tack wind direction so with one direction you may be enjoying starboard tack jumping and the other port tack jumping The same goes for wave riding Generally speaking locations on the South Coast of the UK are predominantly starboard tack however the Bigsalty search engine can hunt out those rare occasions when you can sample some different conditions based on your search criteria Please note that this level of detail may only be visible through the beach search engine where you can search for locations that jump or wave ride in certain tacks therefore this is a tool mainly for intermediate upwards 2 Location forecast Each location listed has a forecast for the next seven days It s important to recognise that all wave data represents offshore wave conditions not those found directly at your beach This is where your skill comes in to interpret the data for your local breaks based on offshore readings The below data is available to Users Wind speed and direction Notice that whatever the wind speed units used the background colour always represents the Beaufort representation of that wind speed Click here to view the Beaufort scale The wind speed is represented for a height of 10 metres above ground level NB The wind speed does not take into consideration any local affects The arrow points in the direction the wind is blowing e g a northwesterly wind comes from the northwest Wave height and direction This represents significant wave height which is the average height from crest to trough of one in three waves The colours used for backgrounds indicate the following size ranges Like wind direction the arrow points in the direction the waves are heading e g a westerly swell comes from the west Wave period This is the peak wave period in seconds of the dominant waves A sea may consist of many swell types with varying periods but this is the dominant one The colours used for backgrounds indicate the following size ranges Rainfall This is the rainfall in mm over the last three hour period Cloud cover This is the highest percentage of cloud cover present in the atmospheric column out of all the atmospheric layers at the given location as a percentage of the visible sky Temperature This represents the temperature at two metres above ground level Sunset

  • Interpreting wave and swell data
    wave data Understanding Wave Data Help settings Bigsalty Weather Forecasting Understanding wave data Swell Height Because the forecast data corresponds to data not actually at the beach but further out to sea under most circumstances the Swell Height forecasted for a location will actually be smaller when it hits your local break Among the main factors that effect the relative size of nearshore waves are the swell direction and period A higher swell period means the average wave height will tend towards a higher height as the swell has more energy Therefore the Swell Height should be seen as an upper bound which is nearer to being reached on a higher period swell Swell Direction It is important to consider that the direction swell is heading in determines how much energy may or may not be dissipated as it hits your beach If the swell has to wrap a wide angle to reach your beach because of the swell direction then you can expect the swell height at the beach to be smaller than if it hits it directly head on The higher the period of a swell the more successfully it can wrap around headlands Usually the more a swell has to wrap the more organised the sets will be Swell Period Swell Period is key You may be able to tell from the previous explanations of the importance of Swell Period to a wave s characteristics as it reaches the beach Swell period is literally the time between successive peaks of a swell A high period swell has the following characteristics over a low period swell wider more spaced out waves a higher energy swell with this the more likely a decent wave will get through to your beach as it overcomes local currents and wind a faster

    you with the option of using either Wind triggers or Custom triggers to fire out your Big Salty alert emails It is totally up to you which you prefer to use and will likely depend on either which watersports you are interested in or how well you know your swell and wind requirements for your location The Wind trigger is based on the Big Salty Wind Rating System You are able to set a minimum alert trigger of either a 2 or 3 star rating for each location on your Watchlist such that if the Wind Star Rating equals or exceeds your minimum set rating for any set locations you will receive an alert For information on how the Big Salty Wind Star Rating rates conditions take a look at the following Wind Star Rating article 2 4 What is the Custom trigger system The Custom trigger system allows you full control over the exact forecast conditions that fire out your weather alert emails For marine locations subject to wind and swell forecast you are able to set configurations for both wind and swell Since every location works best in a different wind or swell direction you are able to set the following Minimum and maximum wind strength for each wind direction you want to track Minimum swell period and swell height for each swell direction that you want to track Note that if you set both swell and wind configurations for a location it will be necessary for at least one of your configurations for both swell and wind to succeed for you to receive an alert email For that reason if you want to just focus on swell or wind leave the other unset 2 5 How do I use the Big Salty email alerts to tell me when it is going off for wind sports There are two ways to do this by using the Wind system or the Custom system The quickest and most effective way is to set up the Wind for the location you are interested in tracking Doing this will only rate wind directions that are sailable at the location which makes locations you are not so familiar with easier to track Click on the following link for documentation on the Wind Star Rating System The other more specific way is to use the Custom system You can really make your local knowledge work for you by selecting the exact wind directions and wind strength you are interested in Simply set a minimum wind speed and max wind speed you are interested in for each wind direction at the location 2 6 How do I get the email alerts to tell me when the surf is going off Firstly set your minimum swell height and swell period for each swell direction that works for your beach You don t get out of bed for anything less than 14 seconds right Then you ll want to factor out strong winds Set the wind speed
