We like January to get away from the cold at home. Have been just about every Jan since 2002. Weather can be calm, can be windy, can be big swells, can be flat, can get some rain. However it is usually great. Probably on average a little more wind than later in year but not an issue for us when planning. You will need to deal with whatever weather happens no matter what month you go and I doubt anyone can give you a forecast for next year. Go for it and have fun.
