Howzit guys
I'm obviously new to your forum - quick intro: I live and surf in South Africa (Cape Town & JBay) - been surfing for 8 years now and its pretty much my entire life - I work in the IT field and do so because of the flexibility around the job - allowing me to surf as often as possible - the reason I'm posting is because I came across this thread whilst doing some search engine optimization for my site - which happens to be called SUSS (you've used the word in this thread a few times)
Just so happens that my site (aptly named SUSS - Search Utility for Surf Spots) does exactly what you're speaking about here -
The concept is pretty simple - as you say - specific breaks work differently in any set of conditions - its up to you as the surfer to learn those conditions and figure out where to go using your local knowledge. The tool I've written turns this into a for more accurate and tangible skill - SUSS monitors the weather bouys in your area (ie: it would query MagicSeaweed hourly and record EXACTLY what the charts are reporting while you're out surfing) - recording what they say on an hourly basis - you then come back after your surf and record what you experienced at the break you were surfing (the actual conditions) - using those 2 sets of data SUSS is then able to map how certain breaks are likely to behave in certain types of conditions.
In a sentence it gives you the following reporting capabilities: 'the last time we had conditions like these you were surfing at Super Tubes in Jbay for 3 hours - it was 5ft - 5 Stars and a light offshore' - obviously its not worded like that, thats just an example of the type of answer SUSS would provide to the typical question of: "SHEESH! I dunno where to surf today?" - it simple draws a surf report for you and suggests where and when you should be surfing at any given time by comparing the conditions that were recorded against your previous sessions to the foretasted conditions on the day you want to surf.
Dont stress about privacy or crowded breaks either - ONLY you have access to your profile and the breaks you surf - there is the ability to join or create your own Crews (a crew,in SUSS, is a group of surfers who surf the same spots on a regular basis - ideally you and your mates) - if you belong to a crew then you can share your session data amongst your mates which is then used along with your personal session data when searching for waves for you - basically you each benefit exponentially from that shared data. On top of that you chose what spots and session data you wantand dont want to share - so yea, dont stress about crowds and all that - I dont want guys at my local break anymore than you do at yours - I build the tool with that very much in mind.
anyway - the url is
http://www.SUSS.co.za - its free and everything- I wrote it for me and my mates to solve the exact issue that was raised on this forum - it started working so well that my mates asked me to put it online for their mates to use - and word has just been spreading - we've got over 300 people in South Africa using it now
I have only hooked it up to Work for South Africa and Indo (a few of my mates do the Mentawis quite often - so they use it to call sessions there as well) - if you guys are keen to use it for your areas then we must chat - I can hook it up for you - would dig to see how it works down your side - its NAILING it in SA - getting a good bit of publicity around here
its not a totally complete system yet- I work on it almost daily - it's been 2 years in the building and its still got lots more coming -
lemme know if you ous are keen - go check some of the photos in the gallery of the kinda waves we've been scoring thanks to SUSS - for Cape Town waves those things are SMOKIN

as I say - if you're keen to try it out - lemme know and I'll hook it up for your area
Lekke guys - hope you scoring some waves!
go well
