very wrong! The biggest tide of the month, which coincides with the the full moon (as I’m sure most of you already know), always seems to pull in a big swell from somewhere.
This is not to say that this is the only big swell that will arrive every month; far from it. It is just something to bear in mind and usually a guaranteed rise in swell which, in itself, is something to be aware of. It seems to be an extremely reliable measure and peculiar to this part of the world. I have no idea, however, if this is the same for other spots on a similar latitude – I’ll leave you to find that one out!
