Unfortunately I know a Saltburn surfer, whilst discussing who has the right to be there, us or them, she told me that the surfers use Surfcore rather than MSW, apparently much more accurate?
I don't know if she's sending me down the wrong path, but it'll be interesting to find out which one of the two gives the most accurate prediction.
It also gives you the name of the breaking wave, so if you want to look a complete tw@t whilst fishing, telling the lads 'I think that one was a messy waist', you can!!
