I will compile the results and post them hereIf anyone wants to add what it is about the page that's great, for example I like Seabreeze forecast's graphical representation of the wind, the swell and swell period all in the one place.

Why you should use THIS search:
Because any other search includes sites using the mixed metaphor "surfing the web".

Surf forecast and report sites
Two questions:
1. Which surf forecast and reporting sites do you use (all the time)?
2. Which page do you go to (all the time) on these sites?
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.
31 August 2015 - note the choppiness to the surface, especially out-the-back.
This is the green shading to the top of the graph.
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.

Autumn surf

Sydney Surf Report
From new.mhl.nsw.gov.au/data/realtime/wave
MHL, Manly Hydraulics Labs has seven continuously recording buoys off the NSW coast that provide deepwater wave data.
Sydney buoy (no relation to Danny Boy) is moored 10 kilometres due east of Dee Why point in water 100 metres deep.
Remember that these are swells on the ocean not the faces of breaking waves on the beach. This buoy also measures wave direction (others don't).
Its current readings:
Hsig - best represents the average swell height (sig=significant), in metres, of the highest third (33%) of the waves. The sample period is approximately 34 minutes.
Hmax - is the largest individual wave recorded in the 34 minute sampling period.
The biggest swell height. Groundswells (longer period swells, see Tp1) can have "clean-up sets", waves that appear to come out of nowhere.
Direction in degrees where 0 degrees is north (N) and so is 360 degrees. Typically the reading here will be between 90 and 180, or E & S.
Generally, the direction is the direction of Tp1, see below.
Tsig - Significant period = average period of the waves used to define Hsig.
Measures the time between one wave and the next. Close your eyes and imagine a good surf, then imagine a bad surf of the same size. The difference is mostly how far apart the waves are (and the surface chop).
Tp1 - Period of the peak of the energy. The highest reading. There usually is more than one swell being recorded, this reading will give a hint about the best swell.
Still having trouble with degrees & direction?
Think of a clock face with 12 o'clock being N; 3 o'clock is east (E) or 90 degrees; 6 o'clock is south (S) or 180 degrees.
IMPORTANT: This information has been recovered directly from automatic recording equipment and has not been quality controlled by MHL.
This data has been collected under the NSW Coastal Data Network Program managed by Office of Environment and Heritage (OEH).

North Steyne Reports
Surf report for the middle of Manly Beach (Sydney - Australia).
A forecast is what is expected to happen, a report is what is actually happening.
Both can be either numbers that you have to work out what they mean or text that give you interpretation of the raw information. Eventually you will just want the numbers.
Go to yosurfer.com for surf reports they also do forecasts.
Manly Hydraulics Lab. (MHL) give up-to-the-minute reports straight from their wave-rider buoys.
Some sites dress up this raw data and make attractive graphics to show the information.
For example here is some of MHLs simplest data, the current temperature of the water at the Sydney wave-rider buoy.
Note: the sea surface temperature should be the same in both of the above graphics.
This link is to the more complex MHL data for wave height, period and direction:
