The surf forecast has been designed to make it as quick as possible to decide when and where to surf.

It's simple, Go for Green!

  poor

Stormy or messy surf at most beaches

DEEPDIVE will recommend the best sheltered spots.
  flat

Too small to surf

The surf quality is determined from an algorithm that looks at wave height, wave interval, wave direction, wind direction, wind speed and layers on over 30 years of local knowledge surfing in the UK.

Surf Height

There are many ways that people call wave height and it can be confusing. Some measure the wave height as the front of the wave, some the back of the wave. Some surf shop reports change by season. Some forecasts give a huge range of surf height, like "4ft to 8ft".

The Big G scale uses a measure based on average body size, and to keep it simple and useful, we keep it tight with just one number, the height of the set waves.

8ft is double overhead

6ft is head and a half

4ft is head high

3ft is chest high

2ft is waist high

1ft is knee high

There's a lot of variation in how different people judge wave height so to even things out, our surf forecasts are based on an average of thousands of surf reports from many different sources.
