IANAWF (I am not a weather forecaster) but it looks to me like the Southern Hemi Storm Train is lining up nicely for the Whiskey Tango Surf Club’s 2007 visit to Playa Guiones, Nosara, Costa Rica
Here’s what it looks like today (from the StormSurf website):

And here’s the forecast for a week from today (again from the StormSurf website):

So, using my magical power patented technique of Predictive Interpolation, I see us getting the tender juicy bits of storm system #2 when we arrive, followed by the long period high energy leading edge of storm system #3 nearer the end of the trip.
To summarize for the layman – the water will be wet and there will be much playing in it.
Pura Vida!
yay!!! I don’t know, if we’re three weeks out, we could be looking at #3 or even #4 forming in the Indian Ocean next week. I don’t know how it all works, but I agree the water will more than likely be wet…
I never get to go to Costa Rica! You guys have fun. I expect pictures!
