We need a new way to factor wave size.  I think that outside temperature, water temperature and time since last surfed should be factored in.  Obviously the first two would be proportional and the third would be inversely proportional.

Since being cold is just a box you have to tick to surf in Jersey and the UK, we'll give the first 2 slightly less significance.  Let's say water temperature below 15 degrees gets a factor of 1.2, below 10 gets a factor of 1.6 and below 5 gets a factor of 2.  We can use the same scale for outside air temperature as well.

For time since last surfed we would have a minimum factor of 1, being 1 day since last surfed.  For every day not surfed, we could increase the factor by .2.

So let's look at this formula in practice:

Todays wave height was 4 foot, the water temp is 10 degrees and the air temp is 9 degrees so:

• Factored wave height = 4 / 1.2 / 1.5 = 2.23 ft. , not interested

But - I haven't surfed in 2 weeks = 14 days = factor of 3.26 so:

• Factored wave height = 4 / 1.2 /1.5 * 3.26 = 7.24 ft. , on it!

Please use the above formula for quoting wave heights from now on so that I may better plan my day.

Cheers
