My wife and I will be on Oahu for four days right after Christmas (our first trip to Hawaii). We will have a rental car (already reserved) and are interested in driving up to Banzai Pipeline one day to see the surfing - we do not surf ourselves, but would enjoy watching other people do it.
I stumbled on surfline.com and am wondering how far in advance they are able to make reasonably accurate predictions about the conditions. Note that I do a lot of boating and SCUBA diving, so I know things can change quickly on the water - just trying to get a feel for how reliable the predictions might be.
We have tried to build as much flexibility into our trip plans as possible to able to make last minutes adjustments as necessary, and I'm definitely not trying to pick a two hour window on a specific date that is over two weeks away. I was just curious if this was something I could check a day or two in advance and make plans based on that, or if it would have to be more of a "morning of" kind of thing.
