Windyty -v- Windytv

They are changing the name from Windyty to Windytv because in English speaking countries, users had problems pronouncing and remembering WindyTY. They think that WindyTV is easier to pronounce and to remember.

This shows the forecast NSW swell 24 hours from now:

MHL directional spectra translated

These images show the directional spectra from Manly Hydraulics Laboratory (MHL) and the realsurf.com photo for the same day/time from RealSurf.com

Notes: Good ground swells (long period swells) have strong colour away from the middle, chop is energy towards the middle (short period).
A stripy curve of the same period energy is preferable to a blotch or a range of periods.

Spring surf

31 August 2015 - note the choppiness to the surface, especially out-the-back.
This is the green shading to the top of the graph.

Autumn surf

23 March 2016 - Again there is choppiness to the surface.
Note the difference in the green shading to the Spring graphic above and the different strengths of the various periods.

More on MHL graphic

After using the information at least once a day since January 2013 I can tell you how good this graphic is.
Good!

I can now look at surf and visualise what that surf would look like as a DirSpec (directional spectrum).
More importantly I can do the opposite.
So why not extend its use to forecasting?
Let us know if you find a forecast expressed this way..
