I hear you Oliver, it's seven degrees and freezing here in Tas today, sleet falling in the car park and I am dreaming of Namotu too!
I think its better that you dont go, it only makes it worse when you have to come home and the reality hits that the only thing left is the itch of the sunburn on your back. Today was my first day back in the office, I was out surfing on my Sup at Namotu left for two beautiful days a week ago. The left is an awesome wave for Sup, turtles popping up in the take off zone, beautiful colored coral to race over on each wave, warm water!! Oh god I want to go back now!
Its going to be a painful wait for summer while I recover from my post Namotu depression. Don't do it to yourself. I keep day dreaming each wave over and over while I am at my desk it's hell.
